LEAD TIMES FOR KEY BUILDING MATERIALS

Ready-mix concrete: 1 week (this is pretty much available on demand, but a week’s notice will certainly be helpful in busy times)

Blocks: 2 weeks (but lightweight blocks might take longer due to shortages of raw material – allow a month for these)

Bricks: 4 weeks (but it depends what you’re after – handmade bricks could take much longer, so always check with the supplier)

Timber frame house shell: 6-12 weeks

Truss roof: 2-3 weeks

Standard roof tiles: 2 weeks

Standard windows & doors: 4-5 weeks
