We don’t use allowances.

You are looking at a 200 square foot kitchen, signature finish.
●
About twenty minutes, on the phone, at a time you pick
●
We ask about the house, the constraints, and what has to be true when it is done
●
You get a straight read on scope, sequence and what actually drives your cost
●
No charge, no obligation, and nobody shows up at your door unless you ask
