Design a deck and get the boards, joists and price off it.
A free 3D deck designer for installers and builders. Set the footprint, the height and the board. Joist centres, board runs, posts and the customer quote come off the design.
Open the designerDrag to spin it. Change a size and watch it update. This is the live tool, not a video.
What comes out of the design
Width, depth and height above ground, freestanding or fixed to the house. The frame follows the size you set.
Beams under joists, or posts straight to the joists — pick the construction, pick the board range, and the frame updates on screen.
Boards, fixings and cuts costed from the design, ex VAT or inc VAT, with your margin on top. Check every line before you send it.
It works where the job is.
What the deck designer works out
Centres and bearer runs worked out from the size and the board.
How many boards, and where they're cut.
Your board cost, your labour, your margin.
Change one number
Change the depth and the whole job recomputes
Move the width, the depth or the board, and the frame, the parts list and the price change with it — not just the picture on screen. Nothing gets worked out on paper twice.
Questions you'll have
Do I need an account?
No. Design it and price it free. You only need an account to save a design or export the quote.
Can I use my own prices?
Yes. Set your board cost, labour rate and margin, and the quote prices off your numbers, not ours.
What board ranges does it cover?
Timber and composite (WPC), picked from the Materials tab. The range you pick sets the price and the cutting list.
Does it handle a raised deck?
Yes. Set the height above ground and choose beams under joists or posts straight to the joists — the frame follows.
