If your house is 2000 square feet in size, the roof will have 20 roofing squares. Because 1 meter equals 10.76 feet in the metric system, the dwelling space will be around 186 square meters. This means that the house will take up about 9 acres of land. The number of rooms in the house can be determined by dividing the total square footage by the number of square feet in an average room. In this case, the house will have 12 rooms. If you want to know how much it costs to rent a two-bedroom apartment in a city such as Chicago or Boston, use our Rent Jungle calculator. It's also easy to figure out how many parking spaces are needed for a car. Just add up the lengths of all the doors of your house and divide that number by 0.5. This gives you the number of required parking spots. In this case, you need one spot for every door length of 22 feet. If some of the doors are off-site, such as at a garage, then you need only one spot per 22 feet of driveway.
