Home addition planning questions
Before a quote is useful, the most important step is getting clear about the purpose of the addition and the practical constraints around it.
- What problem should the new space solve?
- How should the addition connect to the existing home?
- Will the project affect kitchens, baths, utilities, or structural walls?
- Do you already have drawings, or do you need design/build help first?
- What timing, budget, or phasing constraints should be considered?
Those answers help shape a more useful conversation than a one-size-fits-all estimate.
