addition cost?

[Anonymous]

Thinking about adding an addition to our home. the addition would be 2 floors, where we add about a 100sq ft per floor. Also adding a primary bathroom, and reconfiguring windows and closets in the main bedroom, and each of the two adjoining bedrooms due to the placement of the addition. how much do you think this would cost? i assume more than $100k? but how much more.... before i start bringing people in for estimates, would like to get a rough feel of whether we would move forward with this. thanks!

That sounds like a $250K job at least.

I doubt you can get any builder to give you much of an estimate without seeing the plans. We underwent a similar process in the last two years, and the permits, plans, and additional waterlines would cost over 100K. 300-600K, depending on finishes, was the best we could get from GCs.

Hard to say, but definitely more than $100k.

Depends on which walls you bump out, what sort of plumbing is needed and roof work.

I'd get an architect (who will provide drawings and a structural engineer). They will then put the project out to bid and you can get a fixed-cost bid. We found this was the most affordable process and also allowed us the greatest insight and say in the process.

A 2 story, 200 Sq ft addition is not going to be economical. If you're trying to add square footage to existing rooms rather than add new rooms, that's going to drive up the price a lot.

additions aren't worth it, better to just sell and buy a more suitable house. I've done both and always regret additions. Even better is to build a new house.

This isn't really true, particularly when you have a low interest rate mortgage.

$250 at least, and probably more. Not worth it.

How much (ballpark) does an architect for this type thing cost?

100 sq ft or a 1000 sq ft? It’s not worth adding 100 sq ft onto a house.

Yeah, I’m confused by the 100 sq. feet. Are you bumping out existing space on each floor or adding new rooms? And then the bathroom is in addition to that?

Building a new house is the least economical option. The reason home builders make money is scale and experience with what corners can be cut to be the bare minimum marketable at a certain price point.

Additions are often a good idea if your house is among the smallest in the neighborhood.

I am not sure a 2 story 10x10 addition makes much sense. You should consider going bigger, if possible.

But if it’s simply 2 boxes on top of each other connected to the existing structure in a straightforward way and roof lines will be simple to sort out, and you don’t have to do a ton of rearranging inside the existing structure, it could be relatively straightforward. But that’s not what you described, you are rearranging the bedrooms, adding a bathroom in addition to the addition, etc.

It’s definitely over 100k just for the addition construction mostly driven by contractor profit expectations and the price/availability of labor. Going cost plus could be an option to share risk with the GC, but you should have experience in this department before exploring that option. With everything you listed, I think you’d easily be at 300k.

Consider trimming scope. Or paying now for a set of plans but make it clear you want to do it in phases and do a phase now with what you’re going to do later in mind.

a small bump out to expand a room can be done economically sometimes. An addition where you are adding whole rooms, but at that small scale, is going to be very expensive. There are a lot of costs that add up but are similar whether you add 100 or 700 sq. ft. Sometimes the "economy of scale" really factors in.

thanks all. lots of good feedback. for those interested, it would be 100sq ft per floor - so approx 200 sq ft total added. this would add a small office/guest room to the lower level and on the top level would expand the primary bedroom which would allow us to add a bathroom. the new bathroom isn't in the bump out area, but we would reconfigure the room where the bed would end up in the new added part, and a new closet and bathroom would be in part of the original room.
