Residential estimating

Residential construction estimating

Single-family builds, custom villas, multi-family blocks, remodels, conversions and interior fit-out.

How we approach it

Homes, villas & apartments

Two houses of identical square footage can differ by thirty per cent once the finish schedule is priced properly. So finishes get measured room by room and level by level, not smoothed into a rate per square foot.

On remodels, demolition, temporary protection and making-good are separate lines. Those three are the most common omissions in a cheap estimate and the most common change orders afterwards.

Common omissions we look for

Averaged finishes, missing demolition, waste factors applied inconsistently between trades, and tight urban sites priced as if access were free.

Residential questions

What contractors ask us first

Yes, and remodels get demolition, temporary protection and making-good as explicit lines rather than folded into a rate. Those three are the most common omissions in a cheap remodel estimate and the most common change orders afterwards.

Yes. The same estimate can be reported against a draw schedule so each stage carries its own value, which is what a lender needs to release funds.

Room by room against the finish schedule. Two houses of identical square footage can differ by thirty per cent once finishes are priced properly, so averaging across the floor area hides most of the money.
