London Design Build
Basement Conversion Professionals in Seattle, WA
Average rating: 5 out of 5 stars30 December 2025
“London Design Build (LDB) did a fantastic job on a full basement remodel of our 100+yo house in Seattle. Our previous basement was old, damp, poorly layed out with low ceilings. The remodel by LDB was a complete transformation into a modern, luxurious and functional design consisting of 2-bedrooms, lounge, bathroom wet bar, laundry and storage, all with 8ft ceilings. Ben at LDB was very creative, thoughtful and effective in his design decisions and problem solving giving us a feeling of spaciousness, and comfort and adding enormous utility to our house. The LDB crew were great throughout the project - professional, personable and responsive. A great experience all round and we strongly recommend LDB.”
Better Builders
Basement Conversion Professionals in Seattle, WA
Average rating: 5 out of 5 stars8 December 2025
“We had a very good experience with Better Builders on a full basement remodel including the addition of a new bathroom with shower. They were very open, honest, and personable from the start. They were very helpful in challenging our choices and decisions on our project - ultimately making the outcome even better and more to our liking. We had a very basic basement with 70s style paneled walls, concrete floor, and open ceiling. We used Better Builders to add a wine closet, nice family room, a workout room, a pantry, utility room, and a new bathroom. They worked well with our designer to get to our plans finalized including a spec sheet. They were outstanding at managing their subcontractors, permits, inspections, and general contracting work. Their communication throughout the whole process was excellent - their use of recurring weekly updates was very beneficial. The final product is outstanding and quality is exceptional. We would not hesitate to hire them for any future projects.”
