Additions That Respect Presidio Heights and the Way You Live
Presidio Heights is one of San Francisco's most considered neighborhoods, a quiet grid of tree-lined streets above the Presidio where grand Edwardians, storybook Tudors, and red-tile Mediterranean estates stand shoulder to shoulder. Most were built between roughly 1910 and 1930, which means a home addition here is never a blank-slate project. It is an exercise in matching original millwork, bay window rhythms, and proportion while adding the square footage a modern family actually uses. New Key Construction is a Bay Area design-build firm, so one team handles both the design and the construction of your addition, gives you priced options up front, and shows you photoreal 3D renderings before any permit is pulled.
Whether you are expanding a kitchen into a rear yard, adding a primary suite over a garage, or excavating down for lower-level living space, our process is built around the realities of a Presidio Heights lot. These parcels are narrow, deep, and tightly bordered by neighbors, in a city that scrutinizes exterior changes closely. We design to that reality from the first sketch, not after the fact.
One Team, One Set of Drawings, One Point of Contact
The most common way an addition goes sideways is the handoff. An architect draws something beautiful, a separate contractor prices it months later, and the homeowner discovers the design and the budget were never reconciled. We remove that gap. Our designers and builders sit at the same table, so the addition you fall in love with is the one we can actually build, on a number you saw before we started.
That integration matters more in a home like yours than almost anywhere else. Period Presidio Heights homes hide surprises behind their plaster: balloon framing, knob-and-tube wiring, settled foundations, and original details worth preserving. When the people designing your new primary suite are the same people who will open the walls, decisions get made with full knowledge of what is there. You get priced options up front, a clear scope, and white-glove project management for the months we are on site.
Designed for the San Francisco Permit Reality
Home additions in San Francisco run through the Planning Department before a building permit is issued, and any project that changes the exterior or expands the footprint is reviewed against the Residential Design Guidelines. In the RH-1 and RH-2 districts that cover much of Presidio Heights, that review looks hard at scale, light to neighbors, rear-yard setbacks, and whether an addition reads as a natural extension of the original architecture. Many projects also trigger 311 neighborhood notification, giving adjacent owners a window to respond before approval.
We design for that on purpose. By producing photoreal 3D renderings before any permit is pulled, we let you see exactly how a third-floor or rear addition will sit against your Edwardian bay windows, and we use the same renderings to make the case to Planning and to neighbors. Massing that respects the streetscape, period-matched materials, and a footprint that honors setbacks are how we keep your project moving through review without expensive redesigns. We coordinate the full submittal, from Planning approval through the building permit, so you are not chasing the Permit Center yourself.
Built for the Bay Area Estate Lifestyle
The goal of an addition here is rarely just more space. It is a kitchen that opens to the garden, a primary suite with hard-won light and privacy, a lower level that becomes a media room, or a top-floor study with a glimpse toward the Golden Gate. Because we carry the project from concept through finish, the cabinetry, stone, lighting, and built-ins are designed as one composition. The result feels original to the house, not bolted on.
Frequently Asked Questions
Do I need Planning approval for a home addition in Presidio Heights?
Yes. Almost any addition that expands your footprint or changes the exterior requires Planning approval before a building permit, reviewed against San Francisco's Residential Design Guidelines. Depending on scope, it may also trigger 311 neighborhood notification. We handle the full submittal and design to these rules from the start.
How long does a Presidio Heights addition take from design to move-in?
Most additions run several months of design and permitting followed by several months of construction, and San Francisco's review timeline is a real factor. Larger vertical or below-grade additions on period homes take longer. We give you a realistic schedule with your priced options up front so there are no surprises.
Can you match the architecture of an Edwardian or Mediterranean-style home?
Yes, and on these homes it is essential. We match original millwork profiles, window rhythms, rooflines, and materials so the addition reads as part of the original building, not an obvious add-on. Our 3D renderings let you confirm the match before we pull a permit.
Why choose a design-build firm instead of an architect and a separate contractor?
With one team, the design and the construction budget are reconciled before you commit, removing the costly gap where a beautiful drawing meets a number you never agreed to. It also means the people who designed your addition are the ones opening the walls of your period home. You get one point of contact and white-glove management throughout.
What kinds of additions work best on Presidio Heights lots?
Because these lots are narrow and deep with close neighbors, rear kitchen expansions, third-floor primary suites, and below-grade lower levels tend to add the most usable space while respecting setbacks and the streetscape. The right approach depends on your home's structure and the Planning constraints, which we map out together at the start.
