We want to enlarge our master bedroom (13' side wall x 11' back wall) and add a bath w/ shower. We have a 30 yr old, 24' x 44' bi-level house, cinder block foundation. We would like to build out the back wall 10 ft and across the back of the house 22 ft. the opening on the house itself will be 11' The houses foundation 3 ft underground in the back and the floor of the br is about 8 ft off the ground. I would rather not have to put in a whole foundation for tax and cost reasons. i see some neighbors put there additions on stilts (iron?). Is this a good way to go ? We live in lower NY State. Thanks for your help.

PS: Also instead of a roof I want to put a sundeck on the top of the addition, accessible from outside deck. That might cut down on the weight, don't you think?

It is generally best to build the addition on the same type of foundation that you currently have. a different foundation is prone to moving differently that the house and cause problems with leaks, trim joints, and cracks in wall finishes. If it moves too much, doors and windows will fail to operate.

With plumbing in this addition, you need to isolate it from weather so a full foundation wall is wise there.

A flat roof with walking deck is just as likely to add to the weight load if it is done right

Excellence is its own reward!

In addition when considering a flat roof in New York you must take into account the snow loads during the winter months which is quite a bit.

I have a pear and beam home built around 1947 and was considering a tilt addition in back but what I just read might kick my pipe dream out of the water. Was wanting to add a second story somehow someway and save space in the back yard.
