Out of space? Do not move. Improve. A Kaminskiy addition starts with how you live and what your lot allows: build out, or build up.

Room additions in Poway
More house, where you already live.
A room addition is the way to fix the one thing a good San Diego home gets wrong: it ran out of space. An extra bedroom, a second bathroom, a bigger kitchen, a family room, a suite for a parent, a second story over a one-story house, built to look as if it was always part of the original structure.
Kaminskiy designs and builds room and home additions across San Diego County, from a single bedroom to a second story, permitted and built on one contract. Bathrooms, casitas and guest houses, home theaters, man caves and studies, pool houses and cabanas: we have built every kind of addition to San Diego homes, by building out on the ground floor or building up with a second story. Our designers, architectural drafters and project managers take it from the first sketch to the final walkthrough on one contract, with one fixed price before the first footing is poured. Founded in San Diego by Sergei Kaminskiy, and still founder-led.
Poway's ranch homes on half-acre lots, Green Valley and Old Poway give room for additions, outdoor living and the kind of whole-home remodel families plan to grow old in. Permits for room additions in Poway are issued by the City of Poway. Our design and architectural team drafts the construction documents, a licensed structural engineer stamps them where the scope calls for it, and we submit them and manage the whole process for you.

Room additions in Poway: the lot has room; the plan decides where.
A Poway half acre makes the ground-floor addition the natural choice: a great room, a primary suite, a second living room for a multigenerational household, or a poolside room like our Poway poolside addition in the gallery. The two local checks are the septic system's capacity, where the house is on septic, and the fire zone's construction rules in the hills.
Setbacks and the lot's coverage limit are generous on most Poway lots, so the addition goes where the plan wants it: off the family room toward the pool, or off the hall as a new suite. The City of Poway issues the permit, and no coastal rules apply. Our structural engineer ties the new roof into the old one so the addition reads as original.

In Green Valley, Old Coach and parts of Old Poway the house is on septic, and an addition that adds bedrooms has to fit the system's capacity. We check it before design; when the system needs upgrading, it is a line in the budget from the start.
In Cal Fire's higher fire hazard severity zones the addition is built to the ignition-resistant rules: vents, eaves, windows and roofing, with defensible space around it. We design to them from the first sketch rather than fixing them at plan check.
Families adding a great room or a suite, households bringing a parent in with a room of their own, and owners who want the house to meet the pool. The first meeting is at your home, with the lot's rules in hand.
Finishes are chosen at our Design Center in Rancho Bernardo, about 12 minutes away; the first appointment is a walk through your house with the designer.

How a room addition goes in Poway.
Toward the yard and the view, tied into the existing roof, with the setbacks and coverage confirmed before we draw.
Septic capacity for added bedrooms; ignition-resistant construction in the fire zones. Both are settled before design.
Roof pitch, siding or stucco, eaves and windows matched so the addition looks like 1975 did it better.
A City of Poway building permit and six to ten months from the first visit to completion. If what you need is a separate unit, an ADU may be the better path on a Poway lot.

We do. Permits for room additions in Poway are issued by the City of Poway. Our design and architectural team drafts the construction documents, a licensed structural engineer stamps them where the scope calls for it, and we submit them and manage the whole process for you.
On most half-acre lots the setbacks and coverage limits leave room for a substantial ground-floor addition. We confirm the numbers for your lot at the first visit.

No. It sets the construction rules: ember-resistant vents, protected eaves, tempered windows, a Class A roof and defensible space. We design to them from the start.
With the number of variables in a project like this, it is not easy to estimate without knowing what you want. Where you live, the size of the addition, the age of your home and what the new room holds all change the number. In San Diego County home additions typically run from $350 to $650 per square foot, so a basic addition costs around $100,000 and bump-outs start at about that figure. What we promise is a fixed price in writing before the first footing is poured: at the design and bid presentation you see every line of the scope, the contract and the schedule together. The complimentary in-home consultation is where that number starts.
It depends on the room you add. A great room, kitchen or living room addition may add around 70 percent of its cost to your property value; something smaller, like an extra bedroom, office or bathroom, may add around 15 percent. The size and scope of the project, and the budget you put into it, decide how much the value moves. The bigger return is daily: a home that fits the family in it, and one you did not have to leave.
Building out adds a room on the ground level and is the most common kind of addition. It grows the house's footprint, so a new foundation is poured and some yard space goes to the new room. Building up adds a room, or a whole floor, to the second story, or adds a second story to a one-story house. It keeps your yard, usually needs no new foundation (the existing one may be strengthened to carry the weight) and needs a staircase inside, and your area's rules on house size and height apply. Your designer walks the lot with you and tells you which one the house and the property line allow.
A room addition, also called a bump-out, is usually a single-room structure built onto the house: a bigger kitchen, another bathroom or bedroom, a larger primary suite, a personal office. Added rooms are often built for one purpose, but not always: a combination office and guest room, or a sunroom that doubles as a second living room. It is less expensive than a whole home remodel and adds new life to an older home.
Yes. In-law suites, also called granny flats or accessory dwelling units, can be attached to the house or detached in the yard, and recent changes to state and local legislation have made them easier and less expensive to build on San Diego properties. They add square footage and substantial property value, give parents or guests a private place to stay, and are built with aging in place in mind from the start. Our ADU page covers the types, the rules and what we have built.
