My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.
Is this addition technically cantilevered? Not sure how much of it is an addition, but the breakfast nook is a fantistic use of space, and probably cost-efficient if no foundation was needed?
