Katharine, Other/Just Looking in Boston, MA

My husband and I want to add a family room. What can we expect to pay per square foot?

Asked by Katharine, Boston, MA Thu Jan 1, 2009

We won't be adding any pipes so don't need to calculate any plumbing and we live in the Boston area.

Hello Katherine- Have you built your addition yet? How much did it cost you to do? I see this post is about 5 months old.
I've built a lot of additions, and homes. It all depends of course, but assuming you'll need a new frost wall foundation, and that you don't need any baths or sinks there, I would say $150/ sf is a decent budget #. But it could get up to $200 pretty easily. If you need any further help, please let me know. Thanks and good luck,

Hello I am an assistant designer for a small design/build firm in Boston RuedaHumbert partners. I would disagree with the estimate of 300-400 dollars per sqf for a nice space. If you aren't adding any plumbing, your high price items are going to be windows and doors, then you could look at details you might want such as a fireplace, built ins, and trim and molding details. I would look at 150 - 200 sqf as a rough estimate, but we try not to do our estimates that way because it can be quite inaccurate. It's better to come up with the design, really look at the specific items and materials you'll be including, and estimate from there. If you have further questions you can email me at a.baker@ruedahumbert.com

Nationally, the average for new construction is about $100. In New England, it's more like $200/square foot, and definitely higher in urban areas or upscale suburbs. Remember that even at $200/square foot, the quality of finish details will likely not be to your standards. Shortcuts like hollow-core doors, vinyl windows and low-grade light fixtures are built into the lower cost per square foot price. If you want something like you see in a remodeling magazine, figure on $300-$400 per square foot and up. Aspects of home building that were once standard are now considered luxury so prepare yourself to pay more than you expected or be willing to compromise. Since you are in Hingham, this may not be an issue.

One reason that the price per square foot of additions is so high is because, unlike building a house from scratch where the cost is spread out over a much larger footprint, an addition tends to require a lot of work for a relatively small finished product. Again, remember that you will get what you pay for, so go with the most reputable builder you can find (and add 30% to the estimate and double the timeframe)

Well, that's pretty hard number to pin down accurately, but for sake of discussion, I'd go with 150/SF.
