Questions About Room Additions

We want to add a second story to our house, how do I know if my foundation can hold the extra weight?

We have a house that has a daylight basement. The basement walls are cement blocks and we're wondering if it is strong enough to hold a full second story or if we have to go through the hassle of raising the house and putting in a new foundation like I have been told I will have to do by two different contractors. They have never answered my questions about if I can test the strength of it.

How much does it cost to build a garage apartment?

I live in Cleveland, Ohio, and would like build a two-car garage with a small apartment above it behind my house (there's already a driveway in place) for my mother to live in. I'm imagining a garage of about 22' x 20' with approximately 400 sq. feet of living space on top. My partner and I had a well-regarded garage contractor (Angie's List) give us a guesstimate of $80,000. Another contractor would not give us an estimate, but insisted we needed an architect in addition for the apartment design and suggested we ask him how much it would cost. Doing casual internet searches I've found that $80,000 is on the high end of normal. Without going too cheap or cutting corners, what is your estimate for the least we can spend to build?

Floors and Home Additions

Having completed plans for a small bath addition in Philadelphia, I'm a little worried that the floors won't meet properly. Do I have to cut down to the subfloor on the existing part of the home to find the height for the connection? I need help finding the right level for the foundation.

Calculating Square Footage for Home Additions

I'm trying to get a reliable estimate for a home addition at the back of my existing house in Phoenix. Because of setback requirements, it's going to be a narrow room, much wider than long. Should I call in a contractor to measure the size first or will they measure it as part of writing an estimate?

Looking into expanding our garage. Where do I start?

We want to add on a large area for the RV and convert our 2 car garage into a deeper one with a shop at the back. Our garage is attached to the house by the roof only. We have lots of space to add on to the left side of it, but can't picture how the roof will fit in being taller for the RV. Where do I begin with this project?

Which Room to Choose for Home Additions

The 30-year-old home we bought in Columbus two years ago is too small for us now. I want to know which is a better investment on a home addition, a finished basement or a new bedroom? I'm not aware of any structural problems, which is good, but I don't want to open a can of trouble with a basement unless there's a good return in terms of home value. Any suggestions?

Removing Concrete Stains for a San Diego Home Addition

I want to remodel the garage into an extra bedroom. I think we'll cover the concrete with laminate, but until we get the money for that, I want to get out the oil stains. There all kinds of detergents including TSP, but I was told there's a motorized deep cleaner that you can rent for the job. Do you know about them?

Dryer Vent Backdraft Dampers

We're doing a home addition to gain a laundry room in Orlando. I'm worried about moisture and plan on putting in a decent backdraft damper. How much should I budget for the duct work and damper unit? Are booster exhaust fans really necessary to make sure the damper opens properly?

Putting in a Dormer

This spring and summer I'm finally converting the attic and putting in new kitchen cabinets. The big project is the dormer. From what I've gathered online, the framing and rafters are covered the same way you'd do your roof, with plywood, felt, shingles, and flashing. How do you dry-in the room, insulate it, and still maintain adequate ventilation?

Safety During a Kansas City Home Addition

I have two small children and wonder if there are ways to keep them safe during our home addition. We're adding a bedroom downstairs and my boys are too young for school. Is there a way to protect them from the work and dust without getting in the way of the contractors? We have allergies. Is there something to suggest to the builders?
