Ways to save in Springfield

  • Build up or bump out rather than adding a new foundation footprint.
  • Keep plumbing on the existing wet wall — moving water and waste lines is the costliest change.
  • Convert existing space (garage, attic, basement) at half the per-square-foot cost.
  • Keep the roofline simple; complex tie-ins add framing labor and leak risk.
  • Lock the design before demolition — change orders during construction carry the biggest premiums.
