We work closely with our clients to understand everything from their needs to their design preferences. Then we go to work helping them exceed their goals. www.johnsoncustombuilders.com Our process is completely transparent. Our estimates are designed to provide realistic expectations not best-case scenarios. For us, communication is key and we keep you completely informed every step of the way communicating in a way that helps you anticipate and act to effectively engineer the best possible solutions every step of the way. At Johnson Custom Builders our approach is never just about managing timelines and budgets its about delivering on promises and helping you realize dreams. One look at a Johnson Custom build and you'll immediately understand why so many discriminating customers recommend us to their friends looking for a higher level of customized home building. It's not just about the attention to detail or use of the highest-quality materials or even the custom-crafted details. It's about the personalization. Personalization that comes from a builder that not only knows how to listen but also how to anticipate, communicate and most of all deliver on a promise. A native of Kirkland, Washington, founder Ryan Johnson shares the same core values as the community he has always called home: Integrity, Honesty and Originality. He's been actively designing, building and remodeling homes in the area for over 25 years. And in that time, he has earned a stellar reputation for providing outstanding results crafted with uncompromising integrity and quality. Hes also earned a reputation for delivering on his promises. A+ rating on the Better Business Bureau (BBB) !

"Ryan and his crew did a great job building out Car Port. From the first time we talked to a completed project was about 6 or 7 weeks. He and his crew were very professional and, came on time, and exceeded my expectations with respect to the quality, time to finish, etc. Ryan also collaborated with another team of professionals that were contracted to place Solar Pannels onto the Car Port that was just completed. He made sure that all of their requirements and spec were addressed while building the Car Port. THANK YOU Ryan and Co!"

Sunrooms and Patios questions, answered by experts

Sunrooms can add value to your home, offering a return on investment (ROI) of 20% for a screen room to 50% for a three- or four-season room. Sunrooms may be a more worthwhile investment in warmer climates, where many potential buyers are looking for this feature. In colder areas, a sunroom may be seen as more of a “nice-to-have” rather than a “must-have” and may not be as sought after.

Screened-in porches add value to your home, and you can expect an ROI of up to 70% to 80% if you live in a moderate or warm climate. In colder areas, potential buyers won’t see as much value in the home addition since the unconditioned space will be unusable for much of the year. The quality and size of the screened-in porch will also affect the return you’ll see.

When designing an attached greenhouse, several factors should be considered. These include the orientation and positioning of the greenhouse to maximize sunlight exposure, the structural integrity of the connection to the house, sufficient insulation to regulate temperature, proper ventilation for airflow, and adequate space for plants and pathways. If you’re restricted because of your budget, go with a simpler design to maximize the use of your money.

A professional can design and construct sunrooms or patio enclosures that meet structural standards, optimize environmental conditions, and integrate seamlessly with existing architecture. This ensures the project enhances home value and provides long-term enjoyment.

Yes, it can be worth screening a porch if you live in an area with beautiful weather, since it allows you to enjoy your outdoor space longer in the spring and summer. The additional protected space may even attract more prospective buyers if you intend to sell—especially if you add seasonal features, like a ceiling fan for summer or a heater to winterize your screened porch.
