Most Projects Start Like This

Who to call first?

A builder won’t quote without plans. An Architect won’t price the build. You’re stuck in the middle.

Inconsistent Quotes

No detailed drawings = assumptions. Assumptions = different prices.

Designs without Costs

Great design is pointless if it doesn’t match your budget.

Spiraling Budgets

Problems found on site cost far more than problems solved on paper.

ClearPlan fixes this — before the build starts.

Clear Costs. No Guesswork.

Our fixed fee is often similar to the cost of architectural drawings alone — but includes surveys, building regulations, structural calculations and clear cost breakdowns, giving homeowners far more clarity and control before they build.
