Self-contained timber accommodation cabins for holiday lets, farm diversification, guest accommodation and annexe-style use.

These are more involved than standard garden rooms. A proper accommodation cabin needs a practical layout, sleeping space, bathroom facilities, kitchen provision, heating, ventilation, services and a durable finish for long-term use.

Holiday Cabins & Annexes

Backyard of a modern house with a curved roof, large sliding glass doors, a small deck, a hot tub, and surrounding trees and greenery.
Cozy kitchen with wooden walls, a small dining table set with bowls, glasses, and a coffee pot, black bar stools, and a wood stove. Two windows display a backyard with trees and a garden, and a door opens to an outdoor space with a wooden fence.

Starting Points

Most accommodation projects fall into one of two routes: a self-contained chassis-built holiday cabin, or a larger premium lodge / annexe-style build.

Self - Contained Holiday Cabin

Typical size: approx. 7.0m x 2.55m upwards

Self-contained holiday accommodation needs to be approached as a proper build, not as an oversized garden room.

Bathrooms, kitchens, services, chassis design, insulation, glazing and site access all have a major effect on cost.

As a broad guide, realistic self-contained holiday cabin projects such as The Island Hideaway Malvern, usually start from around £70,000–£90,000+.

VAT treatment depends on the final specification and build route.

Premium Holiday Lodge /

Annexe - Style Cabin

Larger self-contained cabins, holiday lodges and annexe-style buildings require a much higher level of specification than a garden room.

Bedrooms, bathrooms, kitchens, services, heating, glazing, decking, outdoor bathing areas and site access can all have a major effect on the final cost.

As a guide, a larger lodge-style build similar in ambition to Malvern Hills Lodge could sit around £125,000–£150,000+, depending on size, specification, access, services and VAT treatment. These projects make most sense where the building has a clear commercial return or long-term use — for example holiday-let income, family accommodation, or a premium guest space.

What a self-contained cabin typically includes

A self-contained holiday cabin usually includes a sleeping area, shower room, toilet, kitchen or kitchenette, living space, heating, ventilation, lighting, electrical fittings and a finished interior.

Depending on the layout and budget, it can also include fitted storage, built-in furniture, aluminium glazing, timber cladding, decking, a covered entrance, outdoor seating or an outdoor bathing area.

The aim is to create a cabin that works properly for guests, changeovers, maintenance and long-term use — not just a shell with services added afterwards.

Chassis-built accommodation route

For self-contained holiday accommodation, we usually favour a chassis-built, transportable cabin where the site and access allow it.

A typical holiday accommodation cabin can be designed over 7m long and/or over 2.55m wide, with sleeping space, shower room, toilet and kitchen facilities. This allows the cabin to be supplied as a self-contained caravan-style accommodation unit rather than a conventional fixed building.

Where the cabin is designed as a transportable unit and kept within the legal caravan dimensions, including the 3.05m maximum internal height, the cabin itself is not normally treated as a conventional building for Building Regulations purposes.

This route can also allow qualifying self-contained accommodation cabins to benefit from reduced-rate VAT.

The site planning position, access and services still need to be checked, but for many holiday accommodation projects this can be a practical and cost-effective build route.

Experience from our own holiday accommodation

We understand holiday accommodation from both sides: building the space and operating it.

Malvern Hills Lodge is our own self-contained holiday accommodation project near the Malvern Hills, which opened its doors in June 2019.

This experience is useful when designing accommodation for clients. A successful holiday cabin has to do more than look good. It needs a practical layout, durable finishes, easy cleaning, sensible servicing, strong guest appeal and a setting that feels worthy of booking.

It is closer to a small house than a simple garden cabin, and a project of this scale would sit in a higher budget bracket than a standard chassis-built holiday unit.
