We are trying to plan some options with our house and want to know approx cost for an addition as follows:

2 storey, 150 square feet both levels.

Will be bedroom/office space - no plumbing required.

We do not have a basement so it will be on a slab.

Please let me know approx cost.

Hi Sarah, the approximate costs will be $150 - $300 per square foot, depending on the level of finishes you want.

Good Luck with it!

Hi Sarah,

To provide a good answer for the approximate cost of an addition is difficult as there are many variable that need to be known before discussing a budgetary number.

But based on the information provided, you should expect to be in the $60,000-$100,000.

A more accurate budgetary number/range can be given after a performing a site visit and obtaining additional information from you.

Thank you

This is a vague question as there are many variable involved.

Roughly 50 - 80K sounds reasonable for a 300 SQFT addition. This would include drawings, permits, engineering, construction, finish.

Hope this helps,
