Luxury additions & ADUs
The construction on most additions is straightforward. What decides the result is what your parcel legally allows, what your existing systems can carry, and how carefully old meets new.
What this covers.
- 01Casitas and detached ADUs
- 02Primary suite and living space additions
- 03Garage bays and workshop space
- 04Covered outdoor rooms and ramadas
- 05Service, panel and HVAC upgrades
- 06Roof, plaster and trim matched to the house
Nobody should be able to tell.
What the parcel allows
Setbacks, lot coverage, height limits and separation between structures set your envelope before anyone draws a line. For a second dwelling the rules differ by jurisdiction and have been revised in recent years.
We confirm what applies to your address with the authority that governs it, rather than working from what was true on a previous job or in another city.
Whether the house can carry it
An addition draws on systems sized for the original house. Electrical service, panel capacity, HVAC tonnage and duct static, water supply, drainage, sometimes the sewer connection. A casita with its own kitchen and laundry is a real load.
Where capacity falls short, upgrading is routine. You want to know while it is a line in an estimate rather than a change order in month four.
Tying into what stands
How new framing engages existing, how roof planes meet without forming a valley that traps water, how foundations of different ages sit beside each other without telegraphing the join.
Done properly none of it shows. Done casually it shows as a line in the roof, a step in the parapet, or a crack that comes back every year in the same place.
The finish gives additions away
Plaster texture and colour, roof tile weathered twenty years, window proportion, base and casing matching a profile milled long ago. None of it structural, all of it what a visitor notices.
The short version.
