Pick a piece of ground that is more of a rectangle along the road, versus a rectangle deep away from the road.  4. 

The duplex layout is extremely simple, just an over/under rectangle, most boring roof and attic that I can think of....and we’ve never ran into this co thing before.....

I quite often get clients that have a boring rectangle box with a boring roof and they want it modern but don't want make any significant exterior or roof improvements. 

The lot is "Flag Shaped" meaning that this rectangle of grass is connected to the main street by a thin driveway that's about 25 feet wide (ie. we have 25 feet of frontage with the main street).

Rip it all out and put in a new electric fireplace like this one.Or, reface the ugly tile on front, box out the top so it is a square/rectangle, and then drywall it.

Use the Rectangle tool to create a rectangle, then type in the dimensions to set the rectangle to the correct size.

You are getting it anyway...and deserve it.Second, all squares are rectangles, but not all rectangles are squares...and all REI don't have to be entrepreneurs.  

But, I don't know what a reasonable amount to pay him for this work.It is a single story about 1000 square feet, rectangle with vinyl siding. 

For example, a large square, a rectangle half the size of the square and a small sqaure half the size of the rectangle.

First, I would make sure that the 3 acre lot is NOT irregular (square, rectangle, and trapezoid are best).Secondly, does it have a good water well and electricity near the property?
