Before you begin
Start with the space you need and how you want it to connect to your home. An early property review helps identify design possibilities, site constraints and the scope of planning required.
Yes, these can be explored as part of the project. Plumbing, utilities, structural conditions and the connection to existing rooms need to be planned together.
We consider rooflines, exterior materials, window proportions, flooring and the transition between spaces. Architectural planning helps the new work feel connected rather than added as an afterthought.
We coordinate the architectural plans, engineering needs and permit preparation required for your proposed scope with SQFT Creation. The specific requirements are reviewed for your property.
The size, structural work, access, site conditions and material selections shape the scope. We discuss the project-specific budget and stages before construction, including dependencies outside the construction team’s control.
