I’m about to convert my old riverside boathouse into a small art gallery, and the first drafts already show some tricky conflicts — ducts crossing historic beams, tight plumbing routes, and hidden wiring near old joists. Has anyone worked with a custom home builder that really takes the time to vet plans thoroughly before construction starts? I’m hoping to find a team that catches these problems on paper first, like the approach I’ve heard some boutique builders use, to avoid expensive surprises down the line.
