Home Addition Design Plan

Design plan · $397

A floor-plan concept and contractor brief, before the expensive part.

A designer turns your addition idea into a floor-plan concept, mood board, specification list and a brief you can hand to a builder or architect.

What you get

A concept-level design plan for a home addition: a floor-plan concept showing how the new space connects to the house, a mood board for the look, a specification list for windows, doors, finishes and fixtures, and a written contractor brief. Concept design, not permit drawings.

Deliverables

  • Floor-plan concept for the addition and its connection to the house
  • Mood board: exterior and interior direction
  • Specification list: windows, doors, flooring, finishes, fixtures
  • Contractor brief with program, must-haves and open questions
