Definition
The design phase is the planning period where architectural designs, materials, and systems are finalized before construction. It includes site analysis, architectural drawings, structural engineering, and MEP design. Design changes cost significantly less during this phase than during construction.

Design phase includes site analysis, architectural drawings, structural engineering, MEP (mechanical, electrical, plumbing) design, and specifications. Multiple design iterations are common as clients provide feedback. Detailed plans become construction documents and permit applications. Design phase typically takes 8-16 weeks for custom homes. Design costs include architect and engineer fees but prevent costly construction changes.
Pro Tip
Invest in thorough design. Changes during construction cost 2-3x more than design changes.
Example
A design phase includes site plans, floor plans, elevations, sections, building specifications, and detailed mechanical/electrical/plumbing plans.
