Pricing · Samantha Grace Architecture
Published pricing.
Set before you sign.
Every project starts with Pre-Design. The design fee is fixed when you sign and changes only when the scope does. Here is how each fee is set.
01 · Pre-Design
$5,000
Fixed, due at booking. Three meetings and a written report: what your property or space will allow, what it will take, and what it will cost before you commit to design. No drawings or design concepts are produced.
If you continue, the $5,000 is credited in full to your design fee.

| New construction | 11.5% of construction budget |
| Major renovation + addition | 14% of construction budget |
| Full gut renovation | 13% of construction budget |
| Minimum design fee | $25,000 |
Calculated on the construction budget developed in your Pre-Design report. The fee is fixed when you sign the design agreement.
