A single-contract design-build delivery model that collapses architecture, interior design, and construction management into one deliverable defines Keith Roberti Design, Build, Project Management, operating from a Fifth Avenue studio in Hillcrest with LGBTQ+ and transgender safe-space attributes logged on its Google Business profile. Whole-home renovations and custom kitchens anchor the residential scope, with mechanical rough-in, panel upgrades, and subpanel relocations on century-old lath-and-plaster construction worked out alongside Eaton Electric for existing-wall rewires that can't be surface-mounted without losing the historic-review approval. Interior scopes cover cabinetry specification, tile layout, lighting design, and millwork detailing handled in-studio rather than farmed to a separate designer. Zoned ductless mini-split retrofits solve the whole-home climate problem for Uptown bungalows with no existing ductwork, a specific retrofit path where the refrigerant-line and condensate-routing scope of Elite HVAC Repair San Diego ties into the same ceiling cavities being opened for the rewire. The Sagebrush Residence in La Jolla is one of the studio's ground-up single-family builds, managed end to end from conceptual design through final finishes. The flagship project is the 2nd Avenue renovation in Bankers Hill, a historic single-family Victorian converted to a multi-unit residence while preserving period millwork, fenestration, and historic-review facade details.
