Log Cabin Kit Contents: What’s In The Box And What Isn’t

A log cabin kit usually gives you the main parts of the building: the log walls, the roof timbers, and the doors and windows. Everything else depends on the cabin and the package you pick. Floors, roof covering, insulation, the base and the interior finish are where kits differ most. So the best thing you can do is read the “what’s included” list on each cabin before you order. Here’s how to read it, in plain words.

TL;DR

• A basic kit (often called a shell package) normally includes log walls, roof joists, and doors and windows.
• Floors, insulation and interior finishing are often extra, so check the list for each cabin.
• Your base, electrics and any heating are usually planned and paid for separately.
• Size, layout and planning rules matter as much as the parts list, so think about them early.
• With a bespoke cabin, you can ask us to build in the extras you want from the start.

What a log cabin kit usually includes

Think of a kit as a flat-pack building made of solid timber. It arrives in pieces, and you (or an installer) put it together on your prepared base.

According to Tiny Society, as standard, log cabin kits come with log walls, roofing joists, and windows and doors. That’s commonly called a shell package. It’s the cheapest way in, but you’ll still need to buy the flooring, sometimes insulation for the floor and roof, and all the interior finishings.

That’s a good starting point. It’s from a US writer, so treat it as a general guide. Details vary from one UK cabin to the next, which is why the product page matters.

Here’s a simple checklist of the parts you’ll normally find described in a kit:

• Wall logs. Pre-cut timber boards that slot together at the corners. The thickness changes how sturdy and how warm the cabin feels.
• Roof timbers. Joists, purlins or rafters that hold up the roof. On an apex roof cabin these form the classic pitched shape.
• Roof boards. The timber layer that sits under the roof covering.
• Doors. Single or double, usually timber. Custom door styles are possible with a bespoke build.
• Windows. Fixed or opening. Some cabins offer double glazing as an option.
• Fixings and instructions. The screws, nails or brackets needed for assembly, plus a guide to follow. Always check what’s supplied for the cabin you like.

A couple of things sit in a grey area. The floor is one. The roof covering (felt or shingles) is another. Some cabins include them and some don’t, so look for them by name on the listing.

Floor, roof covering, doors and windows: what to look for

These are the four items people ask about most. Here’s what to check for each one.

The floor

A shell package may not include a floor at all. If it does, ask whether it’s floor boards, a full floor with joists, or just the boards. Floor insulation is often a separate item.

If you plan to use your cabin all year, as an office or hobby room, a proper insulated floor makes a real difference to comfort. It’s worth building into the plan from day one.

The roof covering

The roof structure and the roof covering are not always the same thing. The timber boards form the roof, and then felt, shingles or another covering goes on top to keep the rain out. Check that the listing names the covering, and check whether it’s included.

The doors

Most cabins come with a door set. Look at the size, the style and whether it’s single or double. If you want wide glazed doors to open onto the lawn, that’s a perfect job for a bespoke design.

The windows

Check the number, size and glazing type. Single glazing is fine for a summer retreat. For a cabin you’ll use in winter, double glazing is a popular upgrade. We can build in double glazing on our cabins as an option.

Shell package or complete kit?

It’s tempting to pick the lowest price and move on. But the cheapest kit isn’t always the cheapest cabin once it’s finished.

David Woods of Tiny Society points out that it’s really important to know exactly what’s included before you commit, because makers offer different levels of finish. He also notes that a shell can sometimes work out more expensive than a complete kit, because you have to source all your own materials.

Here’s a simple way to compare the two:

Neither is “better”. It’s a personal choice. A shell suits a hands-on owner with time. A fuller kit suits someone who wants less to organise.

What you’ll usually buy separately

Some costs sit outside the kit itself. It’s much nicer to know about them now than to find out halfway through.

1. The base. Your cabin needs a flat, firm surface to sit on.
2. Floor and insulation, if they’re not in the kit.
3. Roof covering, if it’s not included.
4. Wood treatment or paint, unless your cabin has a factory-painted exterior.
5. Electrics, lighting and heating.
6. Interior finishing, such as lining, flooring and decoration.
7. Furniture and fittings.

The list looks long, but you won’t need every item. A simple summer house might need only a base and a coat of treatment. A year-round office needs more.

Get the base right first

The base is the part people forget until the cabin is on its way. It shouldn’t be an afterthought.

Checkatrade’s planning guide says a stable, level base is an important part of planning. The right option depends on the cabin, its size and weight, the ground and the manufacturer’s requirements. Concrete, paving and purpose-designed foundation systems are all possible. Their advice is not to order a cabin and assume the base can be sorted out later. The two need planning together.

In practice, that means:

• Measure the cabin’s footprint, then ask what base size it needs.
• Check the ground. Soft, sloping or uneven areas need more work.
• Book the base before the cabin arrives, so it’s ready and settled.

If you’d like help with the build itself, take a look at our professional installation service.

Power, water and heating

What you need here depends on how you’ll use the cabin. Checkatrade explains that a simple summer house might need little more than lighting. A year-round office or hobby room could need several sockets, heating and a reliable internet connection.

They also suggest planning services before the base and cabin go in where you can. Running a power supply across the garden is much easier before paths, landscaping and the finished cabin are in the way.

A few questions to ask yourself:

• Will I use it in winter?
• How many sockets will I need?
• Do I need internet in there?
• Where will the power cable run from?

For a closer look at heating, our guide on calculating electric heating for your cabin is a handy next read. Any mains electrical work should be done by a qualified electrician.

Planning permission and building regulations

The size of your cabin, and what you use it for, can change the rules. It’s worth a quick check before you order.

According to St Albans City and District Council, building regulations typically don’t apply if the internal floor area is no more than 15 square metres and there’s no sleeping accommodation. They also typically don’t apply for 15 to 30 square metres with no sleeping accommodation, if the building is at least one metre from any boundary.

The council also says the use must be incidental to the main house. That doesn’t cover normal residential uses, such as separate self-contained accommodation or a bedroom, bathroom or kitchen for primary living.

This is England-specific advice, and rules can differ in Wales, Scotland and Northern Ireland. Local conditions matter too, so your own council is the best place to confirm for your garden. For more on this, read our guides on planning permission for log cabins and whether log cabins need planning permission.

Wall thickness, layout and size: the choices behind the parts list

The contents list is only half the story. The choices you make about the cabin change what goes in the box.

Wall thickness. Thicker logs generally give you a sturdier, more comfortable cabin. If you want year-round use, ask about thicker walls.

Layout. A single room is simple. If you want more space, such as an office plus a seating area, look at our multi-room log cabins.

Roof style. A pitched roof gives extra head height. Have a look at our apex roof cabins to see what’s possible.

Purpose. A relaxed garden room might suit a summer house. An open, fully enclosed space might suit a garden pavilion. A cabin for all-year living space is best browsed in our garden log cabins range.

Questions to ask before you order

Keep this list handy while you browse. It saves a lot of back and forth.

1. Is the floor included? If so, what type?
2. Is the roof covering included?
3. What wall thickness is the cabin?
4. Are the windows single or double glazed?
5. What fixings are supplied?
6. Are assembly instructions included?
7. What size base does it need?
8. Is the exterior treated or painted?
9. Can I change the doors, windows or layout?

If an answer isn’t clear on the listing, just ask us. We’re happy to talk it through.

Our view on kit contents

We’ve talked to a lot of people who started out trawling through pages of cabins, trying to compare one parts list against another. It can feel like a chore, and it doesn’t need to be.

Here’s how we see it. Most people don’t want a standard box. They want a cabin that fits their garden and the way they live. That’s why we put so much into bespoke and adjusted builds. Different sizes, wall thicknesses, door and window layouts, multi-room plans, insulation, double glazing and factory-painted exteriors can all be part of the design.

When you tell us what you want the cabin for, we can shape the contents around that, rather than leaving you to piece the extras together afterwards. Our aim is durable, quality timber and a cabin built to your specification.

So don’t worry about getting the list perfect on your own. Tell us how you’ll use the space, and we’ll help you work out what it needs.

FAQ

What is included in a log cabin kit?

Usually the log walls, roof joists, and doors and windows. This is often called a shell package. Floors, insulation and interior finishing can be extra, so check the list for each cabin.

Does a log cabin kit include the floor?

Not always. Some kits include floor boards and others leave the floor out completely. Look for it by name on the cabin listing, and ask us if it isn’t clear.

What do I need to buy separately?

Typically the base, and often insulation, interior finishing and electrics. Roof covering and wood treatment may also be extra, depending on the cabin. A bespoke build lets you include more of these from the start.

Do I need planning permission for a log cabin?

Often not, but it depends on size, height, position and use. Council guidance says building regulations typically don’t apply under 15 square metres with no sleeping accommodation. Check with your local council for your own garden.

Can I change what comes with the cabin?

Yes, on our bespoke builds. You can choose sizes, wall thickness, layouts, door and window styles, and features like insulation and double glazing. Get in touch for a tailored quote.
