That required redesigning the whole deck, it was not rectangular, and has 7 posts.

See if you can squeeze in a modern dual vanity with rectangular under mount sinks that will match your existing tile and wainscot.

Cost for a small 2/1 could look like this$2800 to 3500 for furnace and duct, it depends if you want it sealed, spiral, rectangular,  unit efficiency, etc.$300 for electrical run$50 for CO/smoke detector$300 for gas$600 to build new closet for furnace door, framing, drywall, etc.$800 to provide new soffits, you don't have to do this. 

I have seen some awesome firepits in This Old House magazine and Houzz.com and I decided to make one with the giant, rectangular hole.

For a square or rectangular room, it should be very easy.  

It comes in rectangular strips.You're looking to approach this like a Days in or Hilton Hotel...

With that, you can then lay out a proposed minor subdivision.Read the description, a rectangular or square shape can be divided by reading the legal and simply subtract the area needing to be cut off for the new legal.

. $150/sf could just be a safe number based on standard house styles and finishes in your area, but the actual cost will be based on lots of things: - Size of house - Level of finishes - Basement/No-Basement- Amount of framing (it's cheaper to build a rectangular box than anything)- Type of floor system and roof system - Difficulty of lot access/terrain/topographic - Etc.So, the $150/sf number might be a decent estimate, but until the builder sees the lot, the blueprints/drawings and the material allowances for the house, he'll have no way to know for certain how much it will cost.

It depends on the size, complexity and condition of the floor.If it is a rectangular room with carpet then easy.

I've just finished making a tutorial about how to read a survey and property description (both rectangular and metes and bounds).
