My house is a pre-war semi and the rooms are decent sizes. my living room was extended 5 years ago and now measure 24 x 14 feet. the kitchen was small, but we decided years ago that a south facing pantry wasn't aa lot of use and knocked down the walls and also incorporated the storm porch entry , thus adding about 3 more square yards. i also have my study, which is the original dining room.
I'll wear off a few calories tomorrow. I'm starting turning out the study. I have many books which are out-off-date and no longer very useful
