Engineering-led design-build
Rethink the whole home,
not just one room.
Our Contemporary San Mateo Remodel shows what a coordinated renovation can achieve: four bedrooms, three bathrooms, renewed building systems, and finishes considered throughout the home.
When the kitchen, bedrooms, bathrooms, and building systems all need attention, individual projects can leave a home feeling pieced together. Planning the full renovation creates an opportunity to improve circulation, natural light, storage, and comfort as one coherent design.
With California engineering and contractor licenses, BG brings structural evaluation and construction planning into the layout discussion. We consider how walls, openings, foundations, and service routes affect the spaces you want to create.
Local planning considerations
Begin with the existing home
and its specific setting.
Define what stays and what changes
A whole-home renovation needs a clear distinction between retained work, replacement, and additions. Existing plans, a site visit, and targeted investigation help identify structural and building-system assumptions. This is particularly useful when a house has been altered in stages.
Match the scope to the planning process
San Mateo has a single-family design-review process and project-specific submittal requirements. Exterior changes, additions, and new construction should be discussed with Planning early. The City’s checklist also identifies circumstances that may require historic-resource evaluation, tree documentation, or neighborhood-meeting materials.
Coordinate site and infrastructure work
A hillside property and a flatter parcel near the Bay can raise different questions about drainage, access, and existing foundations. We identify the conditions relevant to your address and coordinate any needed survey or specialist input. Utility upgrades and service work should be considered before construction scheduling is fixed.

From structural changes to the final finish.
We coordinate expanded kitchens and living rooms, redesigned bedroom wings, primary suites, home additions, and complete interior renovations. Cabinetry, lighting, windows, flooring, and mechanical systems are considered together so the finished home feels consistent rather than assembled from separate projects.

Contemporary San Mateo Remodel
We completely remodeled this four-bedroom, three-bathroom San Mateo residence, coordinating architectural design, engineering, construction documents, and the build. New plumbing and electrical systems, contemporary kitchen and bathroom finishes, and a recessed wood dining-room ceiling connect the home.

A realistic plan for scope, selections, and disruption.
Renovation budgets depend on what is being rebuilt as well as the size of the house. Structural changes, service upgrades, concealed conditions, finish selections, and temporary living arrangements all deserve a place in the planning conversation. We clarify allowances and exclusions so you can understand the overall investment.
From first ideas to the final walkthrough
One coordinated process.
Understand & plan
Discuss your goals, review the property, and establish the scope, feasibility questions, and budget priorities.
Design & coordinate
Develop architectural and structural drawings, coordinate needed consultants, and prepare the project for the applicable permit reviews.
Build & finish
Coordinate trades, materials, inspections, and decisions through construction, with a consistent point of contact.
Before you begin
Questions worth asking.
Is a whole-home renovation different from several room remodels?
It gives the layout, structural work, building systems, and finishes one coordinated plan. That can help avoid completing one room only to reopen it for a later phase. We can also discuss a planned sequence if the work needs to be phased.
Do older homes need a historic-resource review?
Age alone does not establish that a house is a historic resource. San Mateo’s single-family checklist identifies situations where an evaluation may be required, including substantial demolition of some older structures. Confirm the requirement for the particular property and scope before finalizing demolition plans.
Can you start if we only have ideas?
Yes. An initial conversation can begin with the property address, your priorities, a rough scope, and any existing plans or photos. We then discuss the design and investigation needed to develop the project.
