❓Below are many of the Frequently asked questions we get about our range of Pent Sloping Roof Interlocking Log Cabins & Summerhouses. Use the down arrows to the right to reveal the answers
A pent roof cabin offers a sleek, modern look with a lower profile that’s ideal near boundaries. Its single‑slope roof provides efficient rainwater runoff and allows for EPDM rubber roofing, which is long‑lasting, low‑maintenance, and leak‑free — making it a practical and contemporary choice.
EPDM rubber roofing is highly durable, long‑lasting, and weather‑resistant. It has no joins, which means it won’t leak, and it provides a clean, modern finish ideal for pent roof designs.
EPDM roofing can last 40–50 years with minimal maintenance, significantly longer than felt shingles. Cedar shingles offer a natural look but require more upkeep, while EPDM is virtually maintenance‑free.
Pent roof cabins are specifically designed for EPDM roofing, which we strongly recommend. Alternative roofing materials are not generally advised due to performance and design considerations.
Yes, pent roof cabins are a popular choice for garden offices and studios. Their modern design, efficient roofing, and insulation options make them ideal for year‑round use. They also give the internal appearance of larger space compared with a similar footprint Apex model.
Absolutely. Pent roofs are built with a slight slope to ensure effective rainwater runoff, preventing pooling and protecting the structure. Linked with our guttering options a Pent model only requires guttering at the back of the building.
Pent roof cabins are designed with a single slope roof, which naturally directs rainwater to one side. Adding guttering is optional but recommended if you want to:
- Protect the base and walls by channelling water away from the structure.
- Reduce dirt splashback and tidelines caused by rain hitting the ground near the cabin.
- Harvest rainwater for garden use, as guttering makes collection simple.
Because the roof falls in one direction, guttering is only required along that single edge.
Yes, insulation is available for floors and roofs as standard upgrades. We can also provide thicker insulation or wall insulation if required.
Yes, wall insulation and additional interior cladding can be added as our best and highest upgrade. Whilst this will significantly increase the cost of the building it will provide additional warmth. The downside to internal wall insulation is you lose the look of a timber building unless you opt for timber cladding.
Pent roof cabins are often chosen for their sleek, contemporary look. They complement modern gardens and urban spaces, whereas apex and hipped roofs offer a more traditional aesthetic.
Pent roofs provide a lower external profile, which can be useful near boundaries, while still offering generous internal headroom.
Yes, the lower height of pent roof cabins often makes them more suitable for boundary placement, helping to comply with planning regulations.
Our cabins are available in a variety of log thicknesses to suit different needs. Thicker logs provide greater strength, insulation, and durability, while thinner logs are ideal for budget‑friendly summerhouses. The thickness of the logs is shown in the individual product specifications, but we have models that have 28mm, 40mm, 44mm 68mm and 70mm interlocking logs. If you need thicker logs, please contact us as we can product buildings using a bespoke service.
You can select from full‑length windows, ¾ height windows, or ½ height windows depending on the model. Each style offers a different balance of light, privacy, and aesthetics.
Most of our cabins are supplied with premium sealed double glazing for excellent insulation and energy efficiency. Budget models may come with single glazing, which is clearly listed under the specifications tab.
Standard options include single solid doors, single half‑glazed doors, double doors, wooden bifold doors, and sliding doors. On selected models, you can upgrade to UPVC doors and windows for enhanced security and low maintenance.
Optional Insulation is available on most pent, apex, and hipped models unless otherwise stated. We also offer upgrades to thicker insulation or wall insulation if you require year‑round comfort.
As everyone has difference budgets and requirements, we have asked customers how they prefer to see the breakdown of the prices and we feel this is the most transparent way. Customers can select the individual components to build their own package which is priced individually so you know what you are getting. Nothing hidden.
All cabins come with a manufacturer’s warranty covering structural integrity and materials. Full details are provided with each product.
In most cases, summerhouses fall under permitted development rights and do not require planning permission. However, this depends on size, height, and placement, as well as your location, so we recommend checking with your local authority.
Delivery times vary depending on the model and your location. Installation can typically be completed within a few days once the base is prepared. If you need a building urgently then please contact us and we may be able to recommend a model available for immediate shipment.
Yes, many models allow customization. Speak to our team about adding extra doors, windows, or other upgrades.
We recommend treating the timber with a high‑quality timber treatment and we recommend Sadolin for its quality, ease of application and longevity. Regular re-application of timber treatment and checks on roofing and glazing will help maintain performance.
Many customers choose to assemble their cabins themselves using the provided instructions. We also offer professional installation services with our own employed installation team if you prefer a hassle‑free experience. Many customers prefer us to install their building especially as they may not have the technical ability, experience or tools required. Our teams are very experienced and offer a very high quality of service backed with years of many exceptional reviews. If you are using a third-party fitter, then take care to ensure they have the correct experience. As our fitters are all directly employed by Cabins Unlimited, we are best placed to install your building. Check if your cabins supplier has their own team as many outsource with negative consequences should something go wrong. Not something you will experience with Cabins Unlimited!
A solid and perfectly level base is essential for any interlocking summerhouse or log cabin. We recommend our Eco-Base Plastic Grid System called Probase owing to it allowing water to drain away from the base of the building but other alternatives including concrete pads, paving slabs, or a timber frame foundation to ensure stability and longevity.
All doors and windows are fitted with quality locks. UPVC upgrades provide additional security and peace of mind.
Yes, with insulation upgrades and a suitable heating source, your cabin can be enjoyed comfortably throughout the year. Please talk to us about our range of air conditioning options that are perfect and cost-effective ways of heating and cooling your building throughout the year.
We offer flexible payment options on many models. Please check the product page or contact our team for details.

Whether you're creating a garden office, hobby room, home gym or relaxing retreat, these upgrades can significantly improve your enjoyment of the building from day one.

Use the dropdowns below to read about why we recommend each of the Optional Extras
Sit Back and Let the Experts Build It
Whilst many customers are happy to purchase their building on a supply-only basis, having your cabin professionally installed provides valuable reassurance that your investment is being assembled correctly from day one.
A log cabin is far more than a flat-pack garden building. Correct installation is crucial to the performance, appearance and longevity of the structure. Doors and windows must be adjusted correctly, roofing systems installed properly, and the building assembled using the manufacturer's recommended methods.
That's why many customers choose to add our professional installation service to their order.
Why Choose Cabins Unlimited Installation?
Unlike many online retailers who rely on subcontractors or don't offer any form of installation service, our installation teams work directly for Cabins Unlimited and specialise in timber buildings. Our experienced fitters install log cabins, summerhouses, garden rooms and other timber structures on a daily basis, ensuring a consistent level of workmanship and customer care.
The Benefits of Professional Installation
✔ Experienced timber building specialists
✔ Employed installation teams rather than third-party subcontractors
✔ Correct assembly using manufacturer-approved methods
✔ Professional adjustment of doors and windows
✔ Faster installation and reduced stress
✔ Peace of mind that the building has been assembled correctly
✔ Reduced risk of common DIY installation mistakes
✔ Support from a team who understand the product inside and out
✔ Proven track record with 15 years of reviews on Trustpilot and Google
For many customers, the installation service is one of the most worthwhile upgrades available, allowing them to enjoy their new building immediately without the time, effort and challenges involved in self-assembly.
Protect Your Investment
Your log cabin is a significant purchase and is designed to provide years of enjoyment. Professional installation helps ensure that the building performs as intended from the very beginning.
Our teams understand the natural movement of timber buildings, how to correctly fit roofing systems, and how to achieve the best possible finish. This experience can make a significant difference to both the appearance and long-term performance of your cabin.
Whether you're purchasing a garden office, workshop, leisure room, home gym or family entertaining space, professional installation helps ensure everything starts off on the right foot.
Already Purchased a Building Elsewhere?
We don't just install Cabins Unlimited buildings.
Our experienced fitting teams are regularly asked to install cabins, summerhouses and garden buildings supplied by other manufacturers and retailers. In fact, many companies selling timber buildings online do not operate their own specialist installation teams, so customers often come to us for a professional fitting service.
If you've already purchased a cabin from another supplier, we'd still be happy to provide a quotation for installation. Our team can assess your requirements and advise on the options available. Click here to request a quote:
Installation Available Throughout the UK
Our specialist fitting teams install buildings across the UK and can provide a tailored quotation based on your chosen model, location and requirements.
Let Us Take Care of Everything
Many customers spend months choosing the perfect building. Professional installation ensures the final stage of the project receives the same level of care and attention.
Whether you're buying one of our cabins or have already purchased a building elsewhere, our experienced team can help turn a delivery of timber components into a beautiful finished building ready to enjoy.
Contact our team today for a personalised installation quotation and discover why so many customers choose Cabins Unlimited to install their timber building professionally.
The Foundation Thousands of Customers Trust
A log cabin is only as good as the base it sits on. That's why the ProBase Foundation System has become one of our most popular upgrades.
Unlike traditional concrete or paving slab bases where water can sit beneath the building and the concrete is porous, a ProBase system is designed to raise your cabin above ground level. Combined with 10mm drainage shingle, rainwater naturally drains away, helping to reduce the risk of moisture build-up beneath the structure.
Why Choose ProBase?
✔ Excellent drainage beneath your cabin
✔ Helps prolong the life of your building
✔ Raised ventilation system
✔ Cleaner, tidier installation
✔ No large concrete slab required
✔ One of our most popular customer upgrades
Many customers also choose to add timber sleeper edging, creating a smart and attractive finish that blends perfectly into the garden landscape.
Is ProBase Right For Me?
If you're looking for a long-lasting foundation with excellent drainage and a professional finish, ProBase is the solution we recommend most often.
Protect Your Investment for Decades
Your roof is your cabin's first line of defence against the British weather.
We only supply high-quality roofing systems designed to provide exceptional performance through heavy rain, strong winds, harsh winters and hot summer months.
Depending on your building design, you'll benefit from either our premium Roofing Shingles or our heavy-duty EPDM Rubber Roofing System.
Premium Roofing Shingles
Traditional Appearance with Modern Performance
Our roofing shingles aren't the basic felt products often supplied with lower-cost cabins.
Manufactured using premium bitumen technology and featuring a self-adhesive backing, they offer exceptional durability, weather resistance and a lifespan of approximately 30 years.
Benefits
✔ Long-lasting weather protection
✔ Premium self-bonding construction
✔ Attractive appearance
✔ Available in multiple colours and styles
✔ Suitable for all apex roof designs
Choose from a range of finishes to perfectly complement both your cabin and garden.
These Shingles can be a little tricky to fit but we are happy to give advice and we have videos on our YouTube Channel to help. If you have not considered getting us to install your cabin then we can take the hassle out of the build and ensure your investment is installed correctly.
EPDM Rubber Roofing System
The Ultimate Flat Roof Solution
If you've chosen a pent roof cabin, our EPDM roofing system provides one of the most durable roofing solutions available.
This is the same type of roofing technology commonly used on modern home extensions and commercial buildings.
Unlike many standard kits supplied elsewhere, our system includes finishing details that make a huge difference to both longevity and appearance.
What's Included?
✔ Heavy-duty 1.2mm EPDM membrane
✔ Premium UPVC fascia trims
✔ Protection for roof edges and fascia boards
✔ Professional finished appearance
✔ Designed to accommodate guttering
✔ Expected lifespan of up to 45 years
The result is a modern roofing system built to protect your investment for decades to come.
Turn Your Cabin into a True All-Year-Round Space
One of the most common comments we hear from customers is:
"I wish I'd insulated it from the beginning."
If you intend to use your cabin as an office, studio, gym, hobby room or relaxation space throughout the year, insulation is one of the best investments you can make.
Its best to do this before the roof covering and floorboards are installed as can be tricky to do it later so we recommend taking the insulation kits with the cabin.
Enjoy Your Cabin in Every Season
During winter, insulation helps retain heat generated by heaters and radiators.
During summer, it helps reduce heat transfer through the roof, creating a more comfortable environment.
It can also assist in reducing condensation issues that naturally occur when warm air meets cold surfaces.
Benefits of Adding Insulation
✔ More comfortable all year round
✔ Helps reduce condensation
✔ Improved energy efficiency and reduced bills
✔ Better heat retention
✔ Cooler during warmer weather
✔ Enhances office and garden room use
Our roof and floor insulation system has been carefully developed specifically for log cabin construction and contains everything needed for professional installation.
For customers planning regular use throughout the year, this is one upgrade we strongly recommend. Whilst our 25mm Insulation kits are perfectly suitable some customers want even better insulation and we are able to provide a cost for most buildings to offer a further upgraded and thicker option. Please call us to discuss on 01603 327345.
Protect Your Cabin and Surrounding Areas
Guttering is often overlooked until after a building has been installed.
However, directing rainwater away from your cabin can play a significant role in protecting both the building and the surrounding area.
Our upgraded 116mm Deepflow Gutter System is designed to handle high rainfall volumes while maintaining a neat and professional appearance.
We also offer to supply a waterbutt option if guttering is selected.
Benefits
✔ Directs water away from your cabin
✔ Helps prevent splashback against walls
✔ Ideal for buildings close to fences or boundaries
✔ Reduces moisture build-up around the cabin
✔ Premium quality domestic-grade materials
✔ Includes downpipes as standard
✔ Order with the cabin to save time and hassle - we will even fit it if you have selected us to install your building.
Apex roof models include two downpipes for maximum drainage performance.
Available in:
- Black
- Anthracite Grey
- White
- Brown
A Small Upgrade That Makes a Big Difference
Customers often see guttering as an accessory, but it's actually one of the simplest ways to help keep your cabin and garden looking their best for years to come.
Protect Your Investment and Keep Your Cabin Looking Its Best
A log cabin is a natural timber building, and like any premium timber product, it requires the correct protection to keep it looking beautiful and performing at its best for many years to come.
At Cabins Unlimited, we've spent years testing and using a wide range of timber treatments. We only recommend products that have consistently proven themselves through real-world use on thousands of timber buildings.
Whether you want a contemporary painted finish, wish to showcase the natural beauty of the wood, or would prefer us to do the work for you, we can supply the products, provide advice, or offer a complete professional painting service.
Exterior Protection – Our Recommended Paint System
Sadolin Superdec Opaque Wood Protection
For customers looking for a modern painted appearance combined with exceptional durability, our preferred product is Sadolin Superdec.
This premium water-based treatment is a self-priming, microporous wood protection system that provides outstanding long-term performance while allowing the timber to breathe naturally.
Unlike traditional paints that can trap moisture, Superdec penetrates and protects while maintaining flexibility, helping to reduce cracking and peeling over time.
Why We Recommend Sadolin Superdec
✔ Available in almost any colour - ask us to colour match!
✔ Attractive solid-colour painted finish
✔ Water-based and environmentally friendly
✔ Microporous formulation allows timber to breathe
✔ Self-priming on most applications
✔ Up to 10 years of protection when applied correctly with three coats
✔ One of the most proven timber protection systems available
Many customers choose Superdec to match existing garden buildings, fencing, windows, doors, or even their home's colour scheme, creating a truly bespoke finish.
We can supply the paint mixed to almost any colour requirement, and most of our building listings include guidance on the number of litres typically required to complete the job.

Prefer the Natural Timber Look?
Sadolin Classic Wood Stain
Not everyone wants to hide the natural beauty of timber.
If you'd prefer to see the grain, character, and texture of the wood while still providing excellent protection, we recommend Sadolin Classic Wood Stain.
This translucent wood stain allows the natural appearance of the timber to remain visible while enhancing its beauty and providing excellent weather protection.
Why Customers Choose Sadolin Classic
✔ Enhances the natural grain of the timber
✔ Attractive translucent finish
✔ Protects against weathering
✔ Ideal for traditional garden buildings
✔ Available in a range of natural wood shades
✔ Proven performance from a trusted brand
For customers who have specifically chosen a timber building because they love the natural look of wood, Sadolin Classic is often the perfect choice.

Internal Timber Protection – A Manufacturer's Warranty Requirement
Protect the Inside as Well as the Outside
One of the most commonly overlooked aspects of timber building maintenance is the treatment of the internal timber surfaces.
To comply with the manufacturer's warranty requirements, the internal timber must also be protected.
Many customers assume that because the interior is sheltered from the weather, treatment isn't necessary. However, moisture in the air can still affect untreated timber over time.
For internal protection, we recommend Sadolin Polyurethane Extra Durable Varnish.
Benefits of Internal Treatment
✔ Helps prevent grey mould caused by airborne moisture
✔ Protects timber surfaces from everyday wear
✔ Reduces staining from dirty hands and fingerprints
✔ Creates a surface that can be wiped clean
✔ Preserves the appearance of the timber
✔ Helps meet manufacturer warranty requirements
Our Recommended Application
To achieve the best protection, we typically recommend:
- 3 coats on floorboards
- 2 coats on internal walls
- 1 coat on ceilings
This provides excellent long-term protection while maintaining the natural beauty of the timber.
Customers who prefer a painted interior can still choose an opaque finish, while those wishing to retain the cabin's natural timber appearance often favour the clear polyurethane treatment.
View Sadolin Polyurethane Varnish:Sadolin Polyurethane Extra Durable Varnish
Our Recommendation
If there's one optional extra that protects every other part of your investment, it's proper timber treatment. Whether you choose to apply it yourself or use our professional painting service, protecting your cabin from the outset will help preserve its appearance, maintain your warranty, and ensure years of enjoyment from your new garden building.
Let Us Do the Hard Work
- Painting a log cabin properly takes time, care, and attention to detail.
- Many customers enjoy carrying out this work themselves, but others would rather spend their time enjoying their new cabin instead of painting it.
- That's why we offer a professional painting service.
- Our experienced team can fully paint and protect both the exterior and depending on postcode the interior of your building using proven products and application methods that maximise protection and ensure an attractive, long-lasting finish.
Why Choose Our Painting Service?
✔ Protects your investment from day one
✔ Helps maximise the lifespan of your building
✔ Enhances the beauty and appearance of the timber
✔ Assists with compliance with manufacturer warranty requirements
✔ Saves significant time and effort
✔ Ideal for customers who don't have the equipment, experience, or desire to paint themselves
✔ Professionally applied using products we know and trust
Whether you're looking for a modern colour-matched garden room, a traditional timber finish, or complete internal and external protection, our team can help.
Ask Us for a Personalised Quote
Because every building is different, painting costs vary depending on the model, size, location, and specification.
