Will it fit your block?

The Sebastian measures 10.99 m wide × 20.79 m deep on the plan. Ideal Homes describes it as suited to a 12.5 m wide block. Your block needs to fit that footprint plus the side setbacks, rear setback and any side access your estate requires. Depth decides your outdoor space, orientation decides where the living areas face, slope decides the siteworks, and estate design guidelines can add facade rules.

If you already have a block, send us the lot plan and we will check the fit before you fall in love with a plan. If you do not, we can work out your budget and area first, so the design you choose fits.
