Process
From first sketch to final walkthrough.
01 / 07
Pre-construction Consultation
We plan ahead — setting goals, identifying challenges, and laying the foundation for a successful build before a single permit is pulled.
02 / 07
Architectural & Structural Design
Our engineers and architects work directly with you to translate vision into measurable, build-ready plans tailored to your site and budget.
03 / 07
Material + finish selections
Cabinetry, stone, tile, paint, fixtures, appliances picked against a written allowance log so the bid doesn't drift during construction.
04 / 07
Financing
Our financing partners lend against the project rather than a salary, with terms that can run up to 30 years and a clear path to refinance once construction wraps. How much of the cost they will carry is set deal by deal, so we introduce you and you get the number from them.
05 / 07
Permitting
We handle the city, the paperwork, and the engineering review — every project goes through compliance before a single trade arrives on site.
06 / 07
Construction
We build it, weekly progress reports. Every trade runs on a timeline, every milestone shows up on your dashboard.
07 / 07
Post-construction Relationship
Avorino values long-term partnerships over one-time transactions. Tiered warranty, walk-throughs, and the same point of accountability after move-in.
