Our founding principles endure today and are at the heart of our operations.

By avoiding multiple subcontractors, we seamlessly complete projects that require multiple disciplines or facets without delays. Our craftsmen have been trained in the "Green Spaces Way". These sets of standards allow us to stand confidently behind our work with an industry best five-year warranty. Our multiple awards from 425 magazine, Angie's List, Houzz, and local industry groups are testaments to our diligence for the highest quality work and client satisfaction. Our reviews from various sites speak to the service that you should expect when investing in your home's outdoor space. Please contact our design team to learn all about the potential your outdoor space holds.

"The work they did is top notch, I love our patio and couldn't be happier with what they've done with the space. They did a lot of work for us over two months to build a patio and beautiful back yard. We love it. That said, our home is a 70+ year old house in Magnolia with concrete pipes. A year or so after they did the work we had a backup. After the plumbers came out they found that a section of the piping had been crushed by a large rock that had been set while they were regrading the area. The repairs were ~15k all said and done then. I contacted Ryan and he looked into their insurance covering it and they weren't going to do it out of pocket. I value my time more than money and I let it go, and Ryan had some guys come out and fix the area that had to be torn up for free, least they can do. Well after they were done the plumbers spotted another crushed section that lined up and should be 'okay'. Fast forward a year, it wasn't we had another backup. They cleared it and we just had it fixed with another 5k bill. Ryan had said they wouldn't do it for free but 'hours and material'. They didn't give me a quote I shrugged and assumed it would be a mornings worth of work. They came out and spent two days, and they just handed me a bill for another $3200, to clean up after damage they caused and I'm paying for."

FAQs for sunroom or patio enclosure building service projects in Mercer Island, WA

A sunroom is a fully enclosed space with walls of windows or glass. It allows you to enjoy the outdoors from the comfort of the indoors, protected from bugs and weather. It functions as an additional room in your home. A covered patio extends your home's roof over an outdoor area, providing shade and shelter while remaining open to the fresh air. It's a great way to enjoy outdoor living while being protected from sun and rain.

Adding screens to your porch is the most budget-friendly way to enclose it. Screening keeps out insects and debris while letting you enjoy the breeze and outdoor ambiance. It's less expensive than installing full walls or glass enclosures and doesn't usually require permits, making it an efficient way to upgrade your porch.

If you're transforming your porch into a fully enclosed living space like a sunroom, you'll likely need a sturdy foundation, such as a reinforced concrete slab, to support the structure. For a simple screened-in porch, you might be able to use the existing floor and support posts without additional foundation work. It's best to consult a professional to determine what's needed for your project.

An enclosed porch can be considered a living space if it's fully enclosed with solid walls and windows, has a proper roof, and includes heating and cooling systems. It should also have direct access from inside your home. When these criteria are met, the space becomes an extension of your home's livable area.
