I need to have an 11 X 25 ' room addition added to the back of my house. ... how much per square foot should i expect to pay?

Asked by Kevin, Irving, TX Fri May 25, 2012

there is an existing concrete patio slab that is approx 10X22 the room addition will be built over

It will end up being 3 rooms (an extension of an existing closet, an 8X11 utility room with w/d connections and an 11X11 sun room/breakfast nook) with all tile floors and sheetrock walls - one exterior door (move existing) and prob 3 windows in breakfast nook - maybe one small one in utility room

Hi Kevin. I am an interior designer as well as a real estate broker and I design home additions, new builds, etc. as well as sell them so I can really help you with this question.

If you want to email me and let me know the address of the home I can help you out. Also, if you're planning to stay in the home forever, overbuilding for the neighborhood is not always a bad thing. It can raise property values around you if others follow suit and typically, eventually, you will recoup your investment if you stay in your neighborhood long enough. It just depends on the neighborhood.

Hope to hear from you.

Contact me and I will pull comps to make sure your addition doesn't outdo the neighborhood making it sometimes impossible to recover investment upon resale.

Depends on quality and materials used labor should be pretty close but the price will vary so much. For example you can build a cheap addition with textured wood siding (cheap in cost but more in maintenance), a step up is a Hardy cement siding product that lasts longer, then brick and stone etc... You can see the picture. I can recommend contractors used in the past by clients.
I look forward to helping in any way I can. Please do not hesitate to call, text or email with any questions you may have.

Best Regards,

Thank you - i will actually be matching the existing vinyl siding (in fact, will be able to re-use some that will be removed from the old exterior wall)

You need to confer with a contractor to obtain that information. No professional can render an opinion UNLESS they are the company doing the work

That is hard to say. I would speak with several contractors and get bids and descriptions of the work they will be doing. You also want to get references and see examples of completed projects. That can be photos or actually going out and seeing the actual work.

It does not always pay to go the cheapest route so make sure you know what you are getting and best of luck to you.

Hi, depending upon the extent of the addition and quality of the addition. I would suggest you get a few bids from contractors with specifications that you want i.e. type of doors, windows, sheetrock, paint finish, flooring - wood or tile, insulation, duct work, ac, etc. The more information you can give the contractor the closer to the cost they will bid. Also, you may want to take suggestions from a contractor that has experience to get an idea of floorplan, etc.

Call me if you wish to get names of contractors.

Good luck with the addition.

Suggest you get a couple of quoates from contractors. The link is to a list of contracts that our company has put together that would be a good starting point for your search.


No matter who you use make sure you get the proper permits from the City of Irving. When it comes time to sell your home in the future you do not want an addition done without permits and construction not to code because it could cause you big problems.

Best of luck in you home addition ... Bruce

Building extension is about 125-200 per sq ft. It depends on the qualify of the flooring and exterior of the matterial.

Make sure you at least get 3 bids prior to making a decision.
