Home board recommendations

I’m planning on building a homeboard, I have room for a board that’s 7 feet across and I have ceilings that are 9’3. Planning on building either a 30 or 35 degree overhanging wall and throwing on as many wooden holds as possible. I want something that’s easy enough to climb now (currently plateaued at v5 indoors and around v2+ outdoors) as well as longevity for the future as I progress. I’m hoping to mount it to the walls as a more permanent structure but may have to resort to freestanding. Wondering what people’s thoughts are and if this is to small of a space. Thanks! 

Why not an adjustable angle board?
