Design Your Own Garden Office
National Drylining Building Kits
Design your garden building — shed, office, gym, or workshop — from a fully SFS-framed kit. Set your dimensions, choose your roof and foundation, add doors and windows, and see a live 3D view. Then get a full materials breakdown and step-by-step build guide.
Building Type
Dimensions
Along the ridge / longest side
Across the span / shortest side
Wall height to top of wall frame
Auto-set for apex and mono-pitch
Planning check: Within typical permitted development limits for a garden building of this size.
Roof
Typical for garden buildings: 15° to 40°. Lower pitch will need a waterproof membrane or EPDM.
Listed for reference — customer to source.
Foundation
All National Drylining kits assume a flat, level base — either concrete slab or ground screws.
Select the SFS stud width for the frame. Larger sizes give more rigidity and can span further, but cost more.
Cladding
Choose the colour for the boarded view of your building.
Openings
Add doors and windows. Each can go on any wall, at any position along that wall.
