I'm still looking to build at some point in the next year or two but haven't quite found the plan I want. This one seems pretty close.
Some changes I'd make: I'd want the walls to be concrete masonry units and not wood.
I'd like to reduce the number of doors leading to the back patio (replace them with windows) - I don't like having multiple points of entry from the back. I don't really want exterior doors in the master bedroom either. I'd like a pool.
I took the advice from the previous thread and looked for a plan with a non-front-facing garage, a decent amount (but not too much) of space for a single 40-something guy and a cat to live in for (hopefully) the rest of his life (with the option of adding a partner in the future should one present himself). No Jack-and-Jill bedrooms. Windows on all sides of the house.
There'd be one guest bedroom and another one I can use for a home gym. The only thing I'm not sure about is the dining room - I don't really need it but I suppose it could be repurposed if I really wanted to, or perhaps I could put a piano in it. I don't plan on throwing parties or having many people over. It's all for me.
I like the straightforward layout of the house. No stairs, three car garage (Useful for storage and hobbies), and I like the shade of the front and back porches.
