Hiring an Architect for New Construction vs. Renovation: What Is Different?
Working with an architect feels different depending on whether you are building from scratch or renovating an existing home. Understanding those differences helps you prepare for the process and set realistic expectations.
New Construction: Starting from a Blank Page
New construction projects give the architect maximum creative freedom — there is no existing structure to work around. The process typically involves:
- Site analysis: views, solar, topography, access, utilities
- Full design from scratch: floor plan, massing, exterior, systems
- Complete permit drawings without reference to existing conditions
- More predictable construction cost because there are no unknowns inside existing walls
Architect fee: Typically 10-15% of construction cost for full residential service
Total timeline: 18-30 months from design to move-in
Renovation: Designing Within Constraints
Renovation projects require understanding the existing building before designing. This adds steps:
- Existing conditions survey: measuring and documenting the existing home
- Structural investigation: understanding what can and cannot be changed
- Integration: making new work connect seamlessly with old
- Discovery risk: existing conditions may not match expectations once walls are opened
Architect fee: Often higher percentage (12-18%) because renovation design is more complex per square foot
Total timeline: 12-20 months depending on scope
The Key Difference
New construction is about opportunity — you can do anything the site and zoning allow. Renovation is about problem-solving — how to get from what exists to what you want. Both require an experienced architect, but the design process is fundamentally different.
