for first-time self builders
Where do we even start, and what should this cost?
We asked ourselves the same thing. Self Build Budget turns a floor area into a budget you can adjust, then keeps it honest as real quotes and payments arrive.
Free to start. No credit card required.

"We've never managed a budget this big."
"We don't know what a build like ours should cost."
"We don't know what to include, or where to begin."
None of that is a flaw. Nobody shows first-time self builders how to budget a build. That is the gap Self Build Budget fills.

from one first-timer to another
We worked out what we could afford on a crude cost per square metre. Then we realised one square metre in a kitchen doesn't cost what one in a bedroom does. We were going in quite blind.
