From our job sites

It starts below grade.

Whatever we build on top depends on the concrete and framing underneath. It's in our motto for a reason: strong foundations first.

How we work

Six steps, no surprises.

Every project follows the same path, whether it's a bathroom or a basement suite. You always know what happens next.

  1. Consultation

    A conversation about what you want to change, how you use the space and when you'd like it done.

  2. DesignOptional

    For interior renovations: work directly with our design team, in your home, to plan the space around your needs and wants. About our design service

  3. Free on-site estimate

  4. Detailed proposal

Design service, for interior renovations

Not sure what you want yet? Design it with us.

Work directly with our design team before anything is built. We come into your space, learn how you live in it, and design the room around your needs and wants, down to the finishes.

  • In your homeWe start in the space itself, with you, not from a catalogue.
  • Layout and space planningHow the room flows, where everything goes, and what's possible.
  • Materials, finishes and fixturesCabinets, counters, tile, lighting and hardware, chosen together.
  • A design that's ready to buildThen the same team builds it, so nothing gets lost between design and construction.

Estimates are always free. Design is a dedicated, paid service, offered separately from your renovation. Ask us about it and choose "Design Service" in the question form.
