Structurally engineered SIPs or a traditional timber stud frame, designed by architects and engineers and built to Timber Development UK (previously TRADA) standards.

Dark grey aluminium doors and windows, triple glazed as standard, with black handles.
Monobloc smart air conditioning: cooling, heating and dehumidifying. Platinum can have an Adax NEO panel heater instead.
Recessed LED spotlights, switches and double sockets, all pre-wired. Platinum adds an external consumer unit and dimmer switching.
SPC floor and redwood cladding on Premium; engineered oak floor and Thermowood cladding on Platinum.
Single-piece EPDM rubber roof, supplied in one piece to eliminate the risk of leaks.
A Redwood-framed external seating area with balustrades and composite decking, plus a fixed tall aluminium window, on every Buckingham.
