Design services

Design decided by the people who build it.

Every finish we specify, we also price, buy, and install. Designing in-house means the building looks the way it was drawn and costs what it was budgeted.

Process

How a building comes together.

  1. I

    Design & Budget

    Design and budget develop together. We price the drawings line by line and set a schedule the lender can underwrite.

  2. II

    Site & Permits

    Neighbor access, protection plans, DOB filings, and utility applications begin before the fence goes up.

  3. III

    Build

    Daily supervision, weekly owner meetings, and monthly requisitions with full backup and lien waivers.

  4. IV

    Close Out

    Punch list, sign-offs, retainage release, and the certificate of occupancy, with as-builts and warranties.
