While no one can give you a firm remodel cost estimate without seeing your exact situation, it is possible to hazard a few ballpark figures for many of the most desired projects.
House additions range from pre-fabricated sunrooms shipped to you by freight delivery on up to full-scale stick-built house additions that substantially add to your home's resale value.
- Build Full-Scale Addition: $80 to $135 per square foot
- Enclosed Porch: $6,500 to $16,000
- Sunroom (9' by 15'): $12,000 (not including installation)
- Sunroom (24' by 15'): $20,000 (not including installation)
- Drywall Ceiling Over Plaster: $2.50 to $4.00 per square foot
The lowly basement at first appears to be a remodel financial slam-dunk. Ten grand? Maybe twenty? But when you factor in the need to deal with complexities like electrical, plumbing, and HVAC systems, along with the sheer magnitude of all of that drywall and flooring, plus sticky legalities for turning the place into a rental unit, you end up with a project that is basically an entire house addition.
Bathroom remodels are the ultimate DIY project, especially if dealing with a second bathroom.
- Surface Bathroom Remodel: $1,000 to $14,000
- Half Bathroom: $4,500 to $6,000
- Full Bathroom: $18,000
- Bathroom Addition (built onto the side of your house): $42,000
