When your garden, your vision, or your requirements don't fit a standard product — bespoke is the answer. We design and build completely custom garden structures from scratch: any shape, any footprint, any combination of materials. Whether it's an L-shaped office, a soundproofed music studio, a garden gym, or something entirely unique, we start with a blank page and build around you.
Any Shape, Any Size
L-shaped, T-shaped, curved rooflines, awkward plots — if it can be designed, we can build it. Nothing is off the table.
Every Detail Your Choice
Size, structure, roof style, cladding, doors, windows, interior finish, electrics, climate control — all specified to your requirements.
Premium Materials Only
FSC and PEFC certified timber, 30+ year cladding options, A-rated glazing, EPDM or metal roofing. No compromises.
SIPs Construction Throughout
Every bespoke build uses structural insulated panels — the same system that gives our standard range its performance.
