Timber frame kits, roof trusses, floor joists and garden rooms
We manufacture the structural timber package for new homes — supplied as a full kit or as individual components — plus garden room kits.
Internal timber frame kits
Most new homes in Scotland are built with a structural timber frame inner leaf, finished externally with a cladding such as render on blockwork, brick or timber. Our open panel internal timber frame kits are manufactured off site in Dalry to your house type drawings and delivered to site, ready for your own erector, builder or joiner to put up.
- Open panel timber frame system
- Manufactured to your architect's drawings and your engineer's approved building warrant design
- Suitable for single plots and multi-plot developments
- Coordinated with roof trusses and mid-floor joists
What a kit includes

Roof trusses
We manufacture timber roof trusses to suit your roof design, supplied as part of a full timber frame package or on their own for builders using other wall construction.
- Truss layouts and truss calculations supplied with your trusses

- Available with a frame kit or as a standalone supply

Mid-floor joists
Mid-floor joists for two-storey and storey-and-a-half homes, coordinated with the timber frame so the floor zone, spans and openings are worked out before anything reaches site.

- Coordinated with the frame and roof design
- Supplied with a frame kit or separately
