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.
