Gardena Sunrooms and Patios serves Manhattan Beach homeowners with four season sunrooms, patio enclosures, and sunroom additions - and we have been working in the South Bay since 2020. We know the tight lots of the Sand Section, the stucco cottages near the Pier, and the custom builds on the Hill, and we pull every permit through the City of Manhattan Beach.

Manhattan Beach sits right on the Pacific, and the daily cycle of marine layer humidity in the morning followed by intense afternoon sun demands a room that can handle both. A four season sunroom with insulated walls, low-emissivity glass, and a mini-split system stays comfortable year-round without putting constant strain on your air conditioner - and the marine-grade materials we use resist salt-air corrosion for the long term.
Many Manhattan Beach homes - particularly the custom builds on the Hill and in the Tree Section - have yards and rear setbacks that are underused because there is no weatherproofed connection between inside and outside. A new sunroom addition designed around your existing roofline and stucco exterior gives you that room without looking like an afterthought from the street.
Enclosing an existing concrete slab patio is often the fastest and most cost-effective path to a new room in Manhattan Beach, where small lots leave limited space for ground-up additions. We assess the slab condition first - older patios near the water can show salt-related concrete degradation that needs to be addressed before we build on top of it.
Manhattan Beach homes are high-value properties with distinct architectural styles - a prefabricated kit room rarely fits the character of a Sand Section cottage or a Hill Section custom build. We design around your specific setbacks, lot dimensions, and existing exterior materials so the finished room looks like it was always part of the house.
Manhattan Beach's mild climate means a well-built three season sunroom is genuinely usable for most of the year - roughly nine to ten months without supplemental heating or cooling. If your priority is capturing more of that coastal air and natural light without the cost of a fully conditioned space, a three season room is a practical option for many properties here.
If you want to enjoy the coastal breeze without insects and blowing debris, a screen room is a lower-cost alternative to a full enclosure. It is also a simpler permitted project - which keeps both the timeline and the budget more manageable for Manhattan Beach homeowners who want an outdoor living upgrade on a smaller footprint.
Manhattan Beach is one of the most expensive housing markets in Los Angeles County, and the homes here range from original 1920s beach cottages in the Sand Section to large three-story custom builds on 27-foot-wide lots. That mix creates real variation in what a sunroom project involves. An older cottage may need foundation assessment and updated framing before a new room can be attached. A newer custom build may have specific architectural details - flat roofs with rooftop decks, stucco exteriors, tight side yards - that require careful design to avoid compromising the existing structure or appearance. A contractor who has not worked in this specific city will not naturally account for those differences.
The coastal environment is the other major factor. Salt air off the Pacific accelerates corrosion on metal components - flashing, fasteners, gutters, and window hardware - at a rate that inland homeowners simply do not experience. The marine layer keeps humidity elevated for hours every morning, which puts stress on caulking, paint, and any exterior wood that is not properly sealed. Then the afternoon sun arrives and the heat load on an under-insulated room can push temperatures to uncomfortable levels. A sunroom built without attention to these two forces - morning moisture and afternoon heat - will create maintenance problems within a few years. Getting the materials and detailing right from the start is the only way to avoid that.
Our crew works throughout Manhattan Beach regularly, and we pull permits through the Manhattan Beach Building and Safety Division on every permitted project. That familiarity with the city's plan check process and inspection stages keeps projects on schedule - knowing what the reviewers look for at each step prevents the back-and-forth delays that slow down contractors working in an unfamiliar municipality.
Manhattan Beach covers under 4 square miles, but the three main neighborhoods - the Sand Section closest to the water, the Tree Section in the middle with its tree-lined streets, and the Hill Section inland with larger lots - are genuinely different to work in. Sand Section lots can be as narrow as 27 feet, which changes how a crew stages materials and accesses the rear of the property. The Hill Section has more space but more architectural variation. Whether your home is a block from the Manhattan Beach Pier or up on the Hill, our crew plans the job around the actual conditions on your specific lot.
We also serve the cities that border Manhattan Beach. Homeowners in Hermosa Beach to the south and El Segundo to the north get the same crew and the same process.
Reach out by phone or through the contact form and describe what you have in mind. We reply within one business day and schedule a site visit at a time that works for you - you do not need to have all the details figured out before reaching out.
We visit your Manhattan Beach property, measure the space, and assess the existing slab or foundation condition. Cost is discussed here - before any contract is signed - so you have a clear picture of what the project involves. The homeowner should be present for this visit; it is where most of the important questions get answered.
We submit plans to the Manhattan Beach Building and Safety Division and manage the full permit process. Once approved - typically two to four weeks for plan check - construction begins. Most rooms take four to eight weeks to build. The crew works in your backyard or at the exterior of your home; the interior stays largely undisturbed throughout.
After construction, the city inspector signs off on the completed work. We then do a walkthrough with you to review every finish detail, explain any maintenance considerations specific to the coastal environment, and confirm the room is exactly what was agreed. You receive copies of the approved permit documents for your records.
We serve all of Manhattan Beach - the Sand Section, the Tree Section, and the Hill. Call us or send a message and we will reply within one business day.
(213) 659-0398Manhattan Beach is a small coastal city in the South Bay area of Los Angeles County, covering just under 4 square miles along the Pacific Ocean. The city has about 35,000 residents and is organized into three distinct neighborhoods: the Sand Section, which sits closest to the water and has the tightest lots and densest mix of original cottages and large new builds; the Tree Section in the middle, known for its tree-lined streets and mix of housing styles; and the Hill Section to the east, with larger lots and more architectural variety. Most homes are single-family and owner-occupied, and the housing stock spans from original 1920s beach bungalows to three-story custom homes completed in the last decade. For more on the history and layout of Manhattan Beach, the city's Wikipedia article has a solid overview.
The Manhattan Beach Pier is the city's most recognized landmark, sitting at the foot of Manhattan Beach Boulevard at the water. The Strand - the paved beachfront path that runs the length of the city - is a daily gathering spot and the address of some of the highest-value homes in the county. The city also hosts the AVP Manhattan Beach Open, one of the most well-known professional beach volleyball tournaments in the country, drawing visitors to the beach every summer. Our crew works throughout all of Manhattan Beach and serves neighboring communities as well. Homeowners in Hermosa Beach to the south will find the same team ready to help with sunroom and enclosure projects.
