3.0m x 3.0m / 10x10 Log Cabins
What is a Log Cabin?
A log cabin (or garden cabin) is a garden building made from thick, solid timber — the logs interlock at the corners to form the walls themselves, rather than being clad over a frame. They're robust buildings that add extra living space and functionality to your home, with multipurpose designs that suit a range of uses.
Log cabins come in all shapes and sizes, with a variety of features to choose from. They make ideal home offices, studios and workshops — but are equally good as a place to unwind. With insulated models letting you use them all year round, a cabin can add an extra dimension to your home. Alongside traditional log cabins, this range also includes our panel-built insulated garden rooms — engineered for proper year-round use.
Do You Need Planning Permission for a Log Cabin?
Our log cabins fall under 'permitted development' and won't normally need planning permission, as long as they:
- Are single-storey
- Aren't intended for permanent residential use
- Have a maximum eaves height of 2.5m
- Don't exceed 4m overall (dual-pitched roof, e.g. apex or reverse apex) or 3m (any other roof, e.g. pent) — when sited more than 2m from a boundary
- Don't exceed 2.5m overall if any part is within 2m of a boundary
- Don't cover more than 50% of your garden
- Aren't built forward of the front wall of your house
Every product page lists the building's ridge height, so check it against the limits above for the spot you have in mind. Bear in mind the base counts towards total height, so a raised base can tip a building over the threshold. Tighter rules apply to listed properties and in conservation areas, and the rules differ outside England — see our log cabin planning permission guide for the full picture.
Log Cabin Insulation for a Comfortable Garden Room
Our thicker log cabins already offer a good level of thermal insulation from the outset. A 44mm cabin, for example, uses the timber’s natural heat-retaining qualities to keep it comfortable inside for more of the year, giving you a comfortable garden room without any extra work.
Some owners choose to add their own insulation as a DIY project. It's a common modification, but it's not something we can recommend: altering the structure this way voids your guarantee, and the results vary widely depending on how it's done. If you want a fully insulated cabin, the reliable route is to choose one built for it from the start.
That's where our insulated range comes in. The BillyOh Outpost, for example, comes with EcoQuilt insulation in the roof, floor and walls plus thick double glazing — a proper year-round garden room, guaranteed, with none of the hassle or risk of insulating it yourself.
How Much is a Log Cabin?
The cost of a garden log cabin depends on a number of variables. The size of the building, the thickness of the logs, the features it has and the need for any extras all affect the cost. Small cabins sit at the affordable end of the range, with log cabin sheds cheaper still, while larger models and pre-insulated garden rooms sit at the top. Use the price filter above to set your budget.
Extra costs to expect would be the need to prepare a base, annual treatment as part of its routine maintenance, and any furniture you wish to add.
FAQs
The size of your log cabin depends on the space you have available in your garden and how you plan to use it. Here’s how to think about it:
- Available Space: Make sure the cabin fits comfortably in your garden, and leave at least 30–60 cm around all four sides for airflow and easy access for maintenance.
- Planning Rules: To stay within permitted development rights, outdoor buildings (including your cabin) should take up no more than 50% of your original outdoor space.
- Intended Use: Pick a size that suits what you’ll do in the cabin. For example:
- Home office: ~10×8 ft (3×2.5 m) is a good starting point
- Garden gym: ~12×10 ft (3.6×3 m) gives room for equipment
- Storage or entertaining: Larger layouts (e.g., 14×10 ft / 4.2×3 m) offer extra flexibility

Unfortunately, since the COVID-19 pandemic, we do not have a showroom open to the public.
Our log cabins are designed as garden rooms, not residential living quarters. So, if you're looking for a holiday log cabin or an annexe for guests to sleep in, this is not the right place!
While there is nothing to prevent customers from modifying these buildings to have plumbing and other house facilities (although this would void the guarantee), a building used as a domicile would require planning permission and Building Regulations approval. It would also need to meet health and safety standards for living quarters, which these cabins are not designed for.
