This house came with a front porch all the way across the front. It was already on a full foundation. Just an open 26 foot long by 7 foot deep. Maybe 7 1/2 foot?? I always liked to stand out there in the sun in winter. BUT it was really too cold for standing very long. I ended up actually having one half of the front porch enclosed. 5 windows around and insulated walls and floor. then opened it up to my house. It was horribly expensive. I am sure I got screwed over big time having it built. But oh well. I love the space.. No extra heat needed for such a small addition and the 6 inch insulated walls. I love your space. I am sure you and dogs will enjoy it too.
