Walls - $1 per sq ft
Paint - $3 per sq ft
Roof - $4 per sq ft
Soil - $5 per cubic ft
Hint: Remember to multiply your yard sq ft by the required soil height (4 inches or 0.333 ft) to calculate how many cubic ft of soil you will use!!!
Floors - $11 per sq ft
Windows (4ft W x 2ft H) - $200 per
Doors (3ft W x 7ft H) - $450 per
Note:
Subtract the space taken up by windows and doors for the walls and paint calculations. Once calculated, see how much that amount of paint will cost and put it into your budget proposal.
i.e. - A wall of 20 sq ft with one window would result in 20 - (4 * 2) = 12 sq ft of wall space...
