Frame and truss supplier for the Blue Mountains
Wall frames, roof trusses and floor systems for Blue Mountains homes, from Glenbrook to Katoomba and Blackheath, designed for bushfire ratings and mountain weather and delivered from West Gosford.
Building in the Mountains
Blue Mountains blocks are steep, bushy and often tight, and almost every one carries a BAL rating. We design the frames and trusses to the BAL rating, wind classification and any snow load on your plans, detailed in Pryda software before anything is made.
Many Mountains jobs are rebuilds, extensions and second storeys on older cottages as well as new homes. Send the plans and the engineer's drawings and we'll price exactly what they show.
Steep sites and suspended floors
On a sloping block the house usually sits on a suspended timber floor rather than a slab. We supply floor trusses or I-joists and the flooring with the wall frames and roof trusses, so the whole structure is detailed together.

Every job is designed to the wind classification, BAL rating and any snow load on your plans. Here's what tends to come up in the Blue Mountains. See how the ratings change your frames and trusses.
Bushfire everywhere
The Blue Mountains are surrounded by national park, and most lots are mapped as bushfire prone. Higher BAL ratings change the cladding, windows, sarking and subfloor, and those change the loads the frames and trusses carry.
Snow in the upper Mountains
Katoomba, Leura, Blackheath and Mount Victoria sit around 1,000 metres above sea level, high enough that the engineer may need to allow for snow on the roof. If a snow load is on your plans, the trusses are designed to it.
Ridge-top wind
Houses along the ridge and on escarpment edges catch the westerlies, so the wind classification can be higher than in sheltered gullies and the lower Mountains.

Floor trusses and I-joists for suspended floors on sloping blocks.
Timber and beams
Pine in MGP10 and MGP12, LVL, and glulam beams for anything cut on site.
Blue Mountains questions
Can you supply frames for BAL-rated sites?
Yes. We design to the BAL rating on your plans and the engineer's drawings, as well as the wind classification and any snow load.
Do I need a snow load for Katoomba or Blackheath?
It depends on the site's altitude and the engineer's assessment. If your plans or engineer specify a snow load, we design the trusses to it. If you're not sure, ask your engineer before you send the plans.
Can you supply an extension on an older cottage?
Yes. Send the plans and the engineer's drawings for the new work and we'll price the frames, trusses and any floor system. For anything cut on site to fit the old house, we supply the framing timber.
