Solid-Roof Patio Rooms on Your Existing Slab
A patio room is built around an insulated roof panel rather than overhead glass. That solid roof shades the whole space and slows heat transfer, while window walls on the sides keep it bright. For Pasadena families who want a TV room, a place for the kids, or a quiet reading room they can use on a warm September afternoon, it's often the most practical option.
Many Pasadena homes, from East Pasadena ranch houses to older homes near Lake Avenue, already have a poured patio behind the house. If that slab is in good condition, we build directly on it, which saves the cost of new foundation work. A design consultant inspects the slab during your free visit, and we submit plans to the Pasadena Permit Center and handle the inspections. Full-size patio rooms are on display at our Buena Park showroom.

PATIO ROOMS WE BUILD
Patio Room Choices for Pasadena Homes
Mix roof, wall, and finish options to suit how you'll use the room. Prefer an open-air space? See our patio covers.
Insulated Roof Panels
EPS foam-core panels span the room with fewer posts and keep the roof from radiating heat down onto you, the main thing that separates a comfortable patio room from a hot one.
Year-Round Patio Rooms
Insulated walls, insulated roof, and high-performance glass let you add heating and cooling and use the room as a true everyday living space.
Operable Window Walls
Open the windows on a mild spring evening and close them when the Santa Ana winds blow ash and leaves through the foothill neighborhoods.
Roof Skylights
Add skylight panels over the center of the room to bring in daylight, a good choice when mature trees already shade the windows.
Walls for an Existing Cover
Already have a patio cover you like? Our enclose your back patio in Pasadena page explains how we turn it into a room.
Electrical & Finishing Touches
Recessed lights, fans, outlets, and French or sliding doors make the patio room feel like part of the house instead of an outbuilding.
WHY PASADENA HOMEOWNERS CHOOSE US
Patio Rooms Built Around Your Slab and Your House
The slab, the roof, and the look from the street all shape a good Pasadena patio room.
Slab Evaluated Up Front
Pasadena patios were poured over many decades to varying standards. We measure thickness and look at footings during the site check so you know early whether the slab can be reused.
Shade Without the Glare
A solid insulated roof blocks the overhead sun while side windows keep views of the garden, which makes the room usable at midday, not just in the morning.
Compatible With Older Architecture
Patio rooms usually sit at the back of the house. We match roof pitch and frame color to your home, and if you're in a landmark district we check whether the room would be visible from the street.
Warranty That Transfers
C-Thru and Duralum patio room systems are manufactured in California and backed by a lifetime manufacturer warranty that passes to the next owner.

PASADENA PATIO ROOM FAQs
Common Patio Room Questions in Pasadena
Three-season patio rooms in Pasadena typically start around $15,000-$25,000. Fully insulated four-season patio rooms usually fall between $25,000 and $50,000+, depending on size, roof, glass, and finish level. Reusing a sound existing slab keeps the cost well under a traditional addition.
A patio room has an insulated solid roof and window walls, so it's shaded and holds temperature well. A sunroom uses more glass for maximum light and views. If you want a room you'll use in the heat of the afternoon, a patio room is usually the better match.
Usually. We check slab thickness, condition, and footings during the free site visit. If it passes, we build on it directly. If it doesn't, we explain the repair or replacement options and costs before you commit to anything.
Yes. An enclosed patio room needs a building permit through the Pasadena Permit Center. We prepare the engineering and plans, submit them, and coordinate each inspection.
It can. In Pasadena's landmark districts, exterior work visible from the street requires a Certificate of Appropriateness, while changes not visible from the street are exempt from that review. Most patio rooms are behind the house, but we verify visibility and your property's designation before submitting.
Expect a few months from contract to completion, mainly for design, engineering, and permitting. After the permit is issued, the on-site build is usually days to a couple of weeks.
