From first visit to final walkthrough

One team for every stage.

Assessment

We survey the house as it stands: the structure, the services, and what the lot and zoning allow.

Design and permits

The new layout is drawn over the existing one, and approvals are in place before work starts.

Strip-out

What is worn out comes off. What is sound is protected and kept.

Rebuild

New framing, wiring, plumbing and walls, built to the new layout.

Envelope and interiors

New windows and doors outside. New kitchens, bathrooms, stairs and floors inside.

Handover

A final walkthrough, a complete set of documents, and a home that feels new.

Renovated living room with oak floors and a garden window
