How much would you spend on materials for a house
with these dimensions?
Area(m²) Cost/m² Cost
Walls 202.80 53
Floor 151.00 95
Roof 256.00 48
Ceiling 179.00 29

How do we find the cost of labor for our house?
For labor we will take the cost of each section
and multiply it by 60
Cost Labor Cost
Walls 10,748.40
Floor 14,345.00
Roof 12,288.00
Ceiling 5,191.00

What is our total cost for this house?
Material cost Cost of labor
Walls 10,748.40 6,449.04
Floor 14,345.00 8,607.00
Roof 12,288.00 7,372.80
Ceiling 5,191.00 3,114.60

How can we change our house?

• Certain money
• Certain dimensions

14
Changes based on money

• What happens to the cost of out house if
• Price of materials are now 50/m² for each
  section of the house
• Price of labor is now 70 of the cost of
  materials
• Price of labor is now 50 of the cost of
  materials
• How would we need to change our house to keep the
  total price under 70,000.00 for each of these
  changes?

15
Changes based on dimensions

• What would happen to the cost of our house if
• The area of the walls were 215m²
• floor was 130m²
• roof was 275m²
• ceiling was 160m²
• How could we change our house if we only had
  60,000.00 to spend on it?
