Our Bangor, Maine, home is a typical two-story saltbox with an attached one-story 22' x 22' garage. We'd like to extend the second floor out over the garage as a recreation area with an 8' x 16' hobby room. We have an asphalt shingle roof. The house is older, so framing is 2" x 4". Heating is by a fairly new boiler system. What type of heating do you recommend, and what's a ballpark price per square foot for these room additions?
We are expecting our first baby in a few months and would like to create a "green" nursery. We live in an old Maine house with plaster walls but, luckily, no lead paint. Would it be better to tear down the walls and start from scratch to make the room green? Or can we work with the existing structure and make other adjustments, such as painting or flooring materials, to make it green for our new baby?
