Amy Mason Design

Designers in Brewster don't pull permits — the contractor does, through the Brewster Building Department. Furnishing and finish selection need no permit; kitchen and bath remodels trigger building, plumbing, and electrical permits, with gas work needing a separate gas permit. The Old King's Highway Regional Historic District covers the Route 6A corridor and reviews exterior changes only — interior selections proceed without commission review. Older bayside cottages often have settled foundations, dated wiring, and salt-air corrosion that complicates hardware and window work, so a designer specifying for a coastal property will usually have the GC walk the envelope first. Wetlands and conservation review can touch additions but rarely intersects with interior scope.

Brewster interior designer fees sit in the Cape coastal range — above mainland mid-tier but generally below the very top Cape estate markets. Hourly rates from established Cape firms commonly run $175 to $350, with principal designers at higher-end practices charging $375 to $600. Flat-fee single-room scopes typically run $5,000 to $12,000. Kitchen-bath selection packages commonly land at $6,500 to $14,000. Whole-house seasonal furnishing engagements are usually priced at 15 to 25 percent of combined construction-and-furnishings budget. Cost-plus procurement markups run 20 to 35 percent over trade. Turnkey seasonal furnishing — handling everything down to linens and tableware — is a common premium scope here.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential interior design work; ask for the registration number and check it before paying a deposit.
