Cost of adding a two storey bathroom addition to the side

8 years ago

So, here is the house. We need to remove a toilet from the kitchen and get a proper ground floor powder room with room for a large coat closet. We're thinking of adding another bathroom on top of that which would be accessible from the office. I'll try to draw a rough plan of the floor layout if I can't get one from the town and share it tomorrow.

Any idea what that might cost? It would be between the deck on the side and where the bush on the side is.

Trying to get an idea of how ok or not the aesthetics would be as well but mostly driven by - we really need these!

I'd put openers at $100k .

Two questions for you:

What do YOU think it will cost?

What would you really like to spend on such a project ???

For a two story addition in this area, we figure $250 sq/ft plus a minimum of $12,000 for each bathroom. It could go much higher depending on our choices in materials, fixtures, etc., but this is probably the minimum.

What is "this area" in both cases? OP, where do you live? StarCraft, where are you located? In my area (Bay Area) it's probably closer to $400 PDF plus the bathroom finishing.

I would think you'd need to contact a local contractor, as well as a structural engineer, in order to receive even a ballpark quote on this sort of job. Maybe talk to your neighbors who have done this, and ask them what they paid, how involved the process is, etc. I could tell you what it would cost to do this where I live, but I can almost 100% guarantee you it would be drastically different from what you would pay there. You would also probably need to contact your city government with regard to pulling permits to see if this is allowed - and if you're in a historic district, you would need the historic preservation group's OK, too.

Thanks so much for the "to do" list. I actually have a friend who is an architect, so that might help us out. It's a rowhouse, so it's not as though we can do any complicated curves or other designs on the structural walls. We want to do as much of the work ourselves as we can, but neither of us is willing to work with electricity. We're OK with plumbing, but given that the house was owner-rehabbed before and not done very well, I'd rather pay a professional to get it straight. We were hoping that we could move the tub into the house before the extension is built because we want a nice clawfoot, which will be impossible to get down the stairs. But all the interior design we can take care of. I'm an artist and have many plans for the interior.

Cost of a second story addition

I can tell you what we're doing in Central Pennsylvania. We are removing one side of our home which is a single story and rebuilding it as a two-story. We're also replacing the whole house roof and siding and adding two windows. This is a three-room addition, with a family room on the first floor and a master bedroom and bathroom on the second floor. Our total cost will be around $90,000. One thing that frustrated me was getting the estimates. It was SO hard to compare apples to apples because every company had different ideas about how to do things, what needed to be done and what they'd include. We went with the company that had the best word of mouth and where the contractor cared enough about details like our electric panel and our heating/cooling systems to look at them before making the estimate.

I'm assuming from what the OP said that they don't want or need hall access to a bathroom that one of the bedrooms isn't going to be used as a bedroom. I also LOL at how home builders are so overspecific in naming the rooms on their floorplans. Like everyone wants a game room in the middle of all the bedrooms and home office, just the thing to ensure a good night's rest or undistracted working at a desk. One small item I find really irksome in this floorplan: the door to the master bathroom toilet room is ideally positioned to (a) block the entry from the bedroom when open, which it assumedly would be when not in use, and (b) whack the person using the sink when unexpectedly opened from inside. Also, that door to the upper left bedroom is a weird one. Perhaps to keep it from blocking access to the J&J bathroom when open, it's hinged on what would otherwise be the wrong side. As it is, especially since the bedroom closet extends further than the door opening, the door must be opened an awkward 180 degrees to enter the bedroom from the hallway. Another reason that favors making the upper right and lower left bedrooms the two en suites. This post was edited by lee676 on Wed, Jan 21, 15 at 15:32

An addition is a whole lot more than just the bath labor/fixtures. Blueprints, foundation, roof, framing, insulation, extending/routing ductwork, electrical, and plumbing can be quite pricey. The only way to know the cost for certain is to start with an architect or home builder/contractor and flesh it out.

I'm in Massachusetts. Its a bump out addition to the existing house.

We have no idea what we'd like to spend. We're pricing out about half a dozen things that 'need' to be done and a few nice to haves.

Currently there is only one full bathroom in the house and a toilet in the kitchen which we really really want to get rid of because we don't like the location, and also need the space. However, we do need at least a powder room on the ground floor and another full bathroom above it to serve the first and second floors.

Knowing the cost would help us decide if we can really get rid of the kitchen toilet and have hope of getting a replacement either now or in the spring.

Really? $400 s/f. Don't want to live there, whereever you are.

LA area, also $400/sq.ft for a high end master bath gut/remodel. The cost of no winter, no summer humidity and sunshine year round! It could be done for less, but I paid top labor rates to a great GC and chose pricy tiles and fixtures.
