A 70mm timber garden cabin is a substantial garden building designed for customers who want greater wall mass, strength and stability than lighter timber buildings. The 70mm interlocking wall boards create a solid structure well suited to regular use as a garden office, hobby room, studio, games room, gym, entertaining space or comfortable garden retreat.
As a garden building retailer, one of the first things we advise customers to consider is how often they intend to use the building. If it will be occupied regularly rather than occasionally, the structure, floor, glazing, roof, base and overall specification become just as important as its appearance. A heavier 70mm wall construction is particularly worth considering when the building is intended to become a genuine extension of how you use your home and garden.
What Does 70mm Wall Thickness Mean?
The 70mm measurement refers to the nominal thickness of the interlocking timber wall boards used to form the main walls of the building. Increasing wall thickness gives the structure greater timber mass and rigidity and can improve the overall feeling of solidity inside the building.
Wall thickness should not, however, be viewed in isolation. A good garden building is a complete system. Glazing, floor construction, roof specification, weather protection, ventilation, the supporting base and the quality of assembly all contribute to how comfortable and durable the finished building will be.
Who Is a 70mm Garden Cabin Best Suited To?
A 70mm building is particularly suitable when the garden room will be used frequently, furnished properly or fitted out for a specific purpose. Typical uses include home working, creative studios, music rooms, exercise spaces, reading rooms, teenage retreats, games rooms and garden entertaining areas.
It can also make sense for larger garden buildings where buyers want a reassuringly substantial timber structure. Before choosing a model, think about furniture positions, storage, electrical equipment, door opening space and how people will move around inside. Buying purely from the external dimensions is one of the easiest ways to end up with a building that feels smaller than expected.
70mm Garden Cabin Specification: What Should You Compare?
Don’t assume every 70mm log cabin is the same. The wall thickness is only part of the story. We’ve seen plenty of buildings that look similar on paper but are very different once you start comparing the details.
When you’re looking at quotes, check exactly what’s included. One supplier may include proper double glazing, a heavy-duty roof, quality flooring and all the fixings. At the same time, another keeps the price down by leaving those items out or using lighter materials. It’s worth looking beyond the headline price to see what you’re actually getting for your money.
Wall Construction
Check the stated wallboard thickness, timber specification, interlocking profile and how the building corners are constructed. Precision machining is important because the boards need to interlock consistently throughout the structure.
Windows and Doors
Glazing has a significant effect on comfort, security and everyday usability. The 70mm buildings shown in this category are offered with double glazing as standard, so when comparing alternatives, check whether equivalent glazing is actually included or appears as a chargeable upgrade.
Floor Construction
The floor is easy to overlook because it is less visible in photographs, but it carries everything placed inside the building. Check whether a proper timber floor is included, what supports it underneath and whether the specification is appropriate for desks, furniture, gym equipment or other intended loads.
Roof Construction
Look beyond the external roof covering and ask what the roof structure itself consists of. The roof must cope with its own weight, weather exposure and the long-term demands placed on the building. Ask what roof covering is included and whether alternative finishes are available.
Base Requirements
A substantial timber building needs a firm, flat and level supporting base. Even an excellent building can develop problems if it is installed on an unsuitable foundation. Doors that bind, uneven gaps and movement through the structure can often be traced back to poor base preparation rather than the building itself. Details of available groundwork and supporting services can be found on our garden building services page.
Assembly and Installation
Establish whether the quoted price is supply only or includes assembly. Professional installation can be particularly worthwhile with a larger, heavier building because correct positioning, squaring and assembly all influence how well doors, windows and wall sections perform.
70mm Cabin Comparison Guide
Occasional garden use: If the building will mainly be used during warmer weekends, your priorities may be appearance, internal space, glazing and convenient access rather than maximum specification.
Home office or studio: Prioritise natural light, double glazing, electrical planning, floor quality, sensible window positioning and sufficient space behind the desk or work area.
Garden gym: Check floor capacity, ventilation, internal headroom, equipment clearance and how doors open around larger machines or free-weight areas.
Games or entertainment room: Allow considerably more internal space than the furniture dimensions alone suggest. Pool tables, seating, televisions, bars and games equipment all need circulation space around them.
Frequent year-round use: Consider the complete thermal envelope rather than wall thickness alone. Roof, floor and glazing performance can have as much influence on comfort as the timber walls, and heating requirements should be planned before installation.
70mm Walls Versus Lighter Timber Construction
The main reason for choosing 70mm walls is usually the desire for a more substantial structure. More timber in the wall produces greater mass and rigidity, which is particularly attractive for larger buildings or rooms intended for frequent occupation.
A lighter building may still be entirely appropriate for occasional leisure use or where budget is the main consideration. The better choice depends on intended use rather than simply choosing the thickest available wall. If you expect to furnish, heat and regularly occupy the room, investing in the underlying construction generally makes more sense than spending most of the budget on decorative extras.
Planning Your Internal Layout Before Ordering
Before selecting a size, mark the proposed internal dimensions on the ground and position temporary boxes or garden furniture where desks, sofas, gym equipment or storage will eventually stand. This simple exercise gives a much better impression of usable space than dimensions on a screen.
Take a close look at where the doors and windows sit before anything is made. A window directly behind a computer screen can make it difficult to work because of glare, and a poorly positioned door can leave you with far less usable wall space than you expected. If something doesn’t look quite right, it’s always better to make changes at the planning stage. Moving a door or altering a window on paper is straightforward; doing it once everything has been built and delivered is a very different story.
The Importance of a Proper Garden Building Base
The base is one of the most important parts of the entire project. It must provide continuous, level support and remain stable over time. A building installed on an uneven foundation can twist as it settles, affecting doors, windows and the way the interlocking wall boards sit together.
Prepare the base before the building arrives and confirm its required dimensions from the final specification rather than estimating them from the advertised nominal size. If you are uncertain about groundwork, ask for advice before construction begins. Our additional garden building services provide further information about available base-building and installation support.
Common Mistakes When Buying a 70mm Garden Cabin
Choosing the Building Before Deciding Its Purpose
Start with what you want to do inside the building. A home office, gym and entertainment room can require very different window positions, electrical layouts, floor space and ventilation. Choosing the appearance first and trying to adapt the room afterwards can create unnecessary compromises.
Don’t Compare Prices Until You’re Comparing Like for Like
It’s easy to be drawn to the lowest price, but it doesn’t always work out to be the best deal. Before you decide, make sure each quote includes the same things. Check the floor, glazing, roof covering, delivery and installation, and see whether any extras have been priced in. A quick comparison now can save you from unexpected costs later.
Assuming Thick Walls Solve Every Thermal Issue
Wall thickness is only one part of the building envelope. Customers intending to use their garden room extensively during colder months should also consider the floor, roof, glazing, ventilation and heating strategy.
Underestimating the Importance of the Base
Trying to save money by installing a substantial timber building on an inadequate foundation can be an expensive false economy. The building needs a flat, stable and correctly sized support from the outset.
Buying a Building That Only Just Fits
Allow working room around the building for installation and future maintenance. Timber walls should remain accessible for inspection and treatment, so squeezing the building tightly against fences, walls or dense planting can create avoidable maintenance problems.
Ignoring Delivery Access
Consider how the components will travel from the delivery vehicle to the prepared base. Narrow side passages, gateways, steps, changes in level and restricted parking should be identified before delivery rather than on the day the building arrives.
Forgetting Electrics Until After Installation
If you expect to use computers, lighting, televisions, heaters, gym equipment or powered tools, decide where sockets and lighting will be required before furnishing the room. A suitably qualified person should always carry out electrical work.
Not Allowing for Timber Movement
Timber is a natural material and responds to changing moisture levels and seasons. Components should not be modified or fixed in ways that prevent the building from behaving as its design requires. Follow the manufacturer’s guidance when adding shelves, internal linings, cabling or other fittings.
Treatment and Ongoing Maintenance
Timber garden buildings need appropriate exterior protection and periodic maintenance. Pay particular attention to end grain, joints and areas exposed to persistent weather. Regular inspection allows small maintenance jobs to be dealt with before they develop into larger repairs.
Keep vegetation away from the walls, prevent soil or landscaping materials from bridging any protective base detail and ensure rainwater can drain away from the building. Maintaining airflow around the exterior helps the timber dry naturally after wet weather.
Can I See the Buildings Before Buying?
Seeing full-size garden buildings before ordering can be extremely useful because photographs rarely communicate wall thickness, door quality, glazing, internal headroom or the overall feeling of space. Customers can find details of our Surrey display locations on the garden building display sites page.
Walking inside several different sizes is often the quickest way to decide whether you need more floor area, additional windows or a different door arrangement. It also allows you to inspect materials and construction details rather than making the decision entirely from photographs.
Questions to Ask Before Requesting a Quote
Before requesting a final quotation, establish the external size you can accommodate, the approximate internal space required, intended use, preferred roof style, door and window requirements, base condition, access route and whether you require assembly or additional services. Providing this information early makes it much easier to compare suitable specifications rather than simply comparing prices.

Frequently Asked Questions About 70mm Garden Cabins
What does 70mm mean on a timber garden cabin?
It refers to the nominal thickness of the interlocking timber boards forming the main wall structure. It is an important specification, but buyers should also compare the floor, roof, glazing, base and assembly requirements.
Are 70mm walls suitable for a garden office?
They can be an excellent starting point for a regularly used garden office because the heavier timber construction provides a substantial structure. For frequent cold-weather use, also consider glazing, floor and roof performance, heating, electrics and ventilation.
Do these buildings include double glazing?
The buildings displayed in this category are offered with double glazing as standard. Check the individual product specification when configuring your chosen model because bespoke choices and optional specifications can vary.
Is a timber floor included?
The current 70mm range is displayed with wooden floors included. Always check the final written specification before ordering so that you know precisely what forms part of your chosen configuration.
Do I need a concrete base?
Not necessarily. The important requirement is a suitable base system capable of providing firm, flat and level support for the complete building. The most appropriate solution depends on the site, ground conditions and building specification.
Can the building be professionally installed?
Installation options are available. This is worth discussing when requesting a quotation, particularly for larger buildings where component handling, accurate assembly and access need to be considered in advance.
Can windows and doors be changed?
Bespoke options are available on suitable models, so discuss preferred door positions, window locations and other changes before the building goes into manufacture. Planning the internal furniture layout first makes these decisions considerably easier.
Can electrics be added?
Electrical services can be planned for garden buildings, and information about available support is provided on our garden building services page. Electrical installations should be designed and completed by an appropriately qualified professional.
How much space should I leave around the outside?
Leave enough access for construction, inspection, treatment and future maintenance. The exact clearance depends on the building and site, but positioning timber walls where they can never be reached makes future maintenance unnecessarily difficult.
Can I use the building throughout the year?
A 70mm timber structure provides a strong basis for frequent use, but year-round comfort depends on the whole specification and how the room is used. Roof and floor performance, glazing, ventilation, heating, orientation and exposure to the weather should all be considered.
Should I choose the largest building that fits my garden?
Not necessarily. It’s tempting to go as big as you can, but it’s worth thinking about how you’ll use the space around it too. Leave yourself enough room to walk around the building, carry out any maintenance and make the garden feel balanced. In our experience, a well-proportioned garden building is usually far more practical than one that’s been squeezed into every inch of available space.
Can I view examples before ordering?
Yes. Visiting a display site allows you to compare construction, glazing, doors and internal proportions in person. See our garden building display sites for current location information.
Choosing the Right 70mm Building
The best 70mm garden cabin is not simply the biggest or most expensive model. It is the one whose dimensions, glazing, access, floor, roof and overall specification match how you intend to use the space. Decide the room’s purpose first, prepare the site properly and compare complete specifications rather than headline prices.
If possible, view examples before making the final decision and discuss any unusual access, base or layout requirements before ordering. A little extra planning at this stage can make the difference between a garden building that merely fits and one that remains genuinely useful for many years.
