Choose the new space and how it connects
Describe what the added room must do and how you will reach it from the existing home. Review doorways, floor levels, rooflines and the effect on adjoining rooms. Include any work needed to restore walls, floors or exterior finishes where the addition connects.
Check what the property can support
An addition needs enough suitable space and a design for its connection to the home. Share surveys, existing plans, utility information and property restrictions. Have the responsible professionals review site limits, structure and the capacity of existing services before relying on a proposed size or layout.
Plan the connection work around the household
Discuss construction access, weather protection, temporary separations and any loss of use of existing rooms. Identify the periods when the new and existing work must connect, and include interior repairs, exterior finishing and cleanup in the written scope.
What to compare in a written proposal
