Design Consideration
Cadaxx’s design process began with a detailed site assessment and zoning review to determine the best layout for the second floor.
Multiple concept options were developed and refined with client input, balancing space, light, and proportion.
Final permit drawings integrated structure, finishes, and City feedback for smooth approval and construction.

Construction
The construction process began with demolition and foundation reinforcement, followed by framing the new second floor and roof structure. Mechanical, electrical, and plumbing systems were installed before insulation and drywall.
Exterior cladding and interior finishes completed the transformation, resulting in a solid, efficient, and beautifully executed home addition ready for occupancy.
