Architectural timber cabins, studios and guest lodges, designed and built by one team, wired and certified by our own electricians.
Price your cabinWe design each one around the garden it sits in: the light, the trees, the view back to the house. Then we build it properly, with the same care you would expect of the house itself.
Proportions, glazing and materials chosen for your plot, not picked from a catalogue.
Groundworks, carpentry, electrics and plumbing under one roof and one fixed price.
C24 structural timber, high-performance insulation and a certified electrical installation.
Each design is a starting point. Choose the closest, then tailor every detail in the price builder.
Images show illustrative designs. Every Valley Forge cabin is built to order for its garden.
Six claddings, each fixed with stainless steel over a ventilated cavity so the timber can breathe.
The comfort of a cabin is mostly the part you never see. This is our standard build, outside to in.
Every choice updates the price and the drawing. Figures include VAT. Your fixed price follows a private consultation at your home.
Measured on the outside of the frame. Most garden offices sit between 3 × 3 m and 5 × 4 m.
What the cabin sits on, and how easily we can get materials into your garden.
Every cabin is fully insulated in the floor, walls and roof, so it’s usable all year.
Double-glazed, toughened glass throughout, in anthracite grey.
Walls and ceiling lined, floor finished, skirting and trims fitted. Ready to move in.
A new armoured supply from your house, its own consumer unit, and a certificate when we finish.
A water feed runs in the same trench as the power. Connecting waste to your drains depends on where they are, so we price that after the site visit.
We walk the garden with you: light, levels, access, drains and the route back to the house.
Drawings and an itemised fixed price. Nothing changes unless you change it.
Screws or slab, then the insulated floor, walls and roof. Watertight within days.
Cladding, glazing, lining and floors, with electrics and plumbing running behind.
Testing, certification and a spotless site. Your cabin, ready for the first evening.
From our base in Tring: north to Milton Keynes, west to Oxford, east to Stevenage and down through South London.
Usually not. A garden building is normally permitted development if it’s single storey, used for something incidental to the house (a study, gym or studio, not a bedroom), and no taller than 2.5 m within 2 m of a boundary. Listed buildings, conservation areas and front gardens have tighter rules. We check on the consultation and manage any application.
Under 15 m² with no sleeping accommodation is generally exempt. Between 15 and 30 m² it’s usually exempt if at least 1 m from the boundary or built from non-combustible materials. Anything with a bedroom, or over 30 m², needs approval. The electrical work is always notified and certified.
Ground screws go in within a day, leave no concrete and suit most lawns and slopes. A slab suits soft ground and larger lodges. We recommend one after seeing your soil and levels.
Most cabins take one to two weeks on site. The price builder shows an estimate as you change size and specification. Glazing lead times usually set the start date.
Yes. Floor, walls and roof are insulated as standard, glazing is double-glazed and toughened, and you can choose panel heating or air conditioning that heats and cools.
A garden building used as a bedroom or guest annexe isn’t permitted development, so it normally needs planning permission and full Building Regulations approval. We prepare the drawings and manage both applications; fees are added to your fixed price after the consultation.
40% when you place the order, 30% once the frame and first-fix services are in, 25% after second fix, and the final 5% once everything is tested and handed over.
Our workmanship is guaranteed for 12 months from handover, and the doors, windows, heaters and other products carry their manufacturers’ warranties. The electrical installation is certified and notified as an NICEIC approved contractor.
It’s built from the same rates we quote with, so it’s close, but it can’t see your garden. Access, ground conditions, the distance back to the house and where your drains run can all move it. Your fixed price follows the consultation.
Tell us a little about what you have in mind. If you’ve tailored a cabin above, we’ll bring it with us.
We’ll call you within one working day to arrange your consultation. If it’s urgent, ring 01442 601383.
