BLC remodeled our primary and guest bathrooms several years ago. It was a large project and the entire team was outstanding in their planning and execution of the work. Recently our primary bath shower was showing a bit of wear in a few places that needed some additional grout. I contacted Bogden, and he was able to work my small job into his busy schedule. His team member who came to do the job was great, complete the work in just a couple of hours and the results were amazing.
Two of our neighbors were so impressed with results of our 2020 bathroom remodels, they both hired BLC and were similarly pleased with outstanding results on their respective bathroom remodels.

Frequently asked questions
Adding an addition to your existing home is generally more cost-effective than building a new house. Home additions make use of existing infrastructure and utilities, which can significantly reduce costs. However, the total expense will depend on the size and complexity of the addition, as well as the materials used.
The cheapest type of home addition is typically a single-room extension, such as a sunroom or a small bedroom. These additions require less structural work and fewer materials compared to multi-room additions or second-story expansions. Costs can be further minimized by choosing cost-effective materials and designs.
The timeline for home additions varies depending on the project’s scope and complexity. On average, a small addition like a single room can take 3-4 months, while larger projects, such as adding a second story, can take 6-9 months. Detailed planning and efficient project management are crucial to staying on schedule.
In Medina, WA, ADUs can be either attached or detached from the primary residential structure. Key requirements include:
- Size: ADUs must be no larger than 1,000 sq. ft. or 40% of the principal dwelling’s floor area, whichever is smaller.
- Parking: One off-street parking space is required.
- Compliance: Must adhere to all construction codes, including building, electrical, fire, and plumbing.
