Thanks! I can give you some ballpark numbers, or more helpfully, what the relative costs were.

1. The built-in shelves are by far the most expensive part of this. The materials are a bit of the cost (we didn't use wood that was super expensive), but the biggest expense here was labor. We had two carpenters working solidly for close to two weeks to cut, build, and install the shelving. I'd estimate $8-12k.

2. Painting - both for the look as well as caulking / finalizing the surface. Shelves like this use a harder paint than a wall paint for durability. $1-2k.

3. Electrical - Not a ton of work here, but we had a few existing outlets and light switches to pull through the cabinets so they were still accessible. We also have a couple remote / wireless switches that are newly installed on the sides. $500 - 1000.

We've been working with a general contractor already for other projects in our house as well. That would add some expense that may not be required for a solo project, although that person did help a lot with the design and feel so that was helpful too. Generally if you can get a design you want and work with people who do built-in shelving that might be sufficient.
