Here at Best Homes, our company is based on the belief that our customers' satisfaction is of the utmost importance. Our team is driven to meet your needs with professionalism, creativity, and efficiency. Established 2005. Owner: Jonathan Perez Office Manager: Paige Marie Campbell Project Manager: Jefry Perez
"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

"Terrible experience. We contracted with Prime Custom (Kamil) to do a full bathroom and kitchen remodel in 2021 and we have had tons of issues. Their license # 2705166476 that they were operating under has been REVOKED as of May 2024. You can check this for yourself by going to the Virginia state website [*** Link removed ***] and entering the License # 2705166476. Yes, the name on the VA state website is different but they were operating externally as Prime Custom. As proof, I have attached a picture of the contract which shows the above License # , and Prime Custom's name. They are now operating under a different license # 2705173804 which I find highly unethical. I have already filed a complaint with the Virginia Department of Professional and Occupational Regulation and they will investigate if any laws were broken. Before considering doing business with Prime Custom, or any other contractor, please ensure that you look up their license number on the above Virginia State website. Summary of my experience: - Bathroom: The shower has developed a major leak which is going through the bathroom floor into the lower level. See pictures. I am contracting with another company to fix, which is going to cost thousands of dollars. Kitchen - It failed gas and safety inspections multiple times. To this day, I am concerned about the structural integrity of the load bearing wall in the kitchen and am contracting with another company to fix. Hopefully, this review can save others from the extremely frustrating experience that I have gone through."

KBA Kitchen and Bath: Transforming Homes with Excellence for Over 25 Years. Proudly Serving Fairfax County and Fauquier County.
"We would like to say thank you to KBA Kitchen & Bath Design & Build for a great job remodeling our two upstairs bathrooms. The two bathrooms were completely renovated in 5 weeks, but it could have been finished even sooner if we hadn’t selected a premium option for our shower glass enclosure. The entire project was started and finished between January 21, 2025 until February 28, 2025, which included the crew working two Saturdays, which shows their dedication in getting the job done. We were very impressed with KBA over the entire project! Specifically, we were impressed at how smooth and efficient the entire process was. It was seamless – from the initial consultation to the execution of the job. The designer, Anna, was very thorough and helpful in sketching the designs of new bathrooms and offering advice on recommended materials for the bathroom, to include going above and beyond in helping us choose just the right paint colors to perfectly blend with our newly installed bathroom accessories. Anna and Ervin both made after hour visits to provide their insight on color schemes and where bathroom accessories should be installed and look best. The lead project manager, Ervin, was always there to answer our questions, and he went out of his way to always ensure we were happy customers! Ervin also visited on many occasions to give us updates on project progress and keeping his crew updated on any changes. The installation team always showed up on time, left the work area clean, and went above and beyond to make our design a reality. Anna, Ervin and the crew were always very friendly, professional, and helpful throughout this project. We couldn’t be happier with the outcome as we absolutely love our bathrooms! We highly recommend choosing KBA for your next home project!"

Guest house building services FAQs
In most states, yes—you can build a guest house, but every city or county sets its own zoning rules and building codes. Before breaking ground, check local ordinances, confirm lot setbacks, and secure the right permits. A local contractor or design-build firm can walk you through the paperwork and site requirements so your project starts on solid legal footing.
Yes—homeowners often tap a few different financing tools. A home-equity line of credit (HELOC) lets you borrow against your equity as you need funds. If you prefer a lump sum tied directly to the project, a short-term construction loan can roll into a second mortgage once the build is complete. Cash-out refinancing is another option: you replace your current mortgage with a larger one and use the difference to cover construction costs.
When you build a guest house, you’re creating a separate structure for hosting visitors without the full amenities needed for permanent living. An accessory dwelling unit, however, includes a complete kitchen and bathroom, meeting building codes for a long-term residence. This key difference makes an ADU ideal for long-term occupancy or rental income, adding enduring value to your property.
How many rooms you need depends on how you plan to use the space. Aim for one bedroom per every one or two occupants to make sure everyone has enough privacy and comfort. Added living and dining areas give you extra functionality, especially for rental use or long-term stays.
Most homeowners pick somewhere between 600 and 1,500 square feet to fit all the essentials. Make sure your design supports one to two occupants per bedroom and includes enough common areas for comfortable daily living. A well-proportioned layout boosts both functionality and property value.
No—a guest house isn’t just a bump-out on your main home. A bump-out is a small extension within an existing room for extra seating or storage. In contrast, you build a guest house as a standalone building with its own foundation and amenities, giving you a fully separate living area that can boost your property’s versatility and value.
