QCB5 Retreat
The QCB5 Retreat is our QCB5 garden office shell finished with a flyover roof and matching front decking — included as part of the build rather than bolted on after. The flyover gives genuine rain protection over the entry and front windows, summer shade to keep the room cooler, and a real sense of arrival from the garden. Decking sits on the same adjustable concrete feet as the building (no concrete base or groundworks needed), and downlights can be set into the flyover for evening use. Underneath all that it's the full QCB5 spec: zero-maintenance cladding, A-rated double glazing, 90mm Ecotherm insulation, pre-wiring for electrics, and the 25-year structural guarantee. Configure depth, decking and air conditioning in the picker — the price recomputes as you compose your build. Free delivery and installation in mainland England, and a £100 deposit reserves your installation date.

And, like every Booths building
A zero-maintenance exterior
Built from steel and UPVC — no external timber. It never needs painting or staining, so you are never left maintaining a building, and it keeps its just-installed look for the full 25 years.
The UK’s only 25-year guarantee
A 25-year structural guarantee on the building itself — not a one or two-year warranty. It is built, and warranted, to be used for decades rather than treated as a temporary garden room.
Portable — and still an asset
Every building is 100% portable. If your circumstances change it can be lifted out and relocated, or sold on, so it stays a resaleable asset rather than money sunk irreversibly into the house.
Customer Stories
Customers with the QCB5 Retreat
QCB5 Retreat — your questions
Listed building or AONB — can I still have an annexe?
Contact your council and emphasise the low carbon output — some planners have approved installations. Material samples are available on request.
Will I need planning permission for my annexe?
Annexes for a family member comply with the Caravan Act and qualify as permitted development, avoiding planning permission. See the Planning Permission page for the full conditions.
We want an art studio — is it suitable?
Yes — many customers use the studios for art and comment on the light, airy feel. Windows on two sides are common; a three-side window option is available.
Can I attach a studio or annexe to my house?
No — studios, offices and annexes cannot be attached to existing properties, though they can be positioned within about 2 inches of one.
Is the base strong enough?
Yes — a decoupled floor accommodates movement (helpful for treadmills/ cross-trainers). Non-moving heavy items (bookshelves, pool tables, printing machinery) are easily handled; discuss heavy moving gym equipment with us.
Can you supply a more bespoke garden office design?
Yes — half windows, high "fan light" windows, decoupled treadmill flooring, external downlights, internal partitions/sliding doors, extra decking, colour options, light oak walls, French doors, flyover roofs, floor and outside sockets, internal storage or toilet cubicles. Contact us for option pricing.
Do you supply bi-fold doors?
No. Bi-fold doors have fine tolerances; very hot weather expands them, making closing or locking difficult or impossible.
Do you supply blinds?
Recessed blinds are included as standard in QCB5 and QC8 layouts.
