Is it cheaper to build up or out on an existing house?

Generally, building up is often cheaper than building out for existing homes because it utilizes the existing foundation and doesn't require new land, but it adds complexity with roof removal, stairs, and structural reinforcement. Conversely, building out can be simpler and less invasive, costing less per square foot if you have the land and don't need foundation work, but it uses more land and can disrupt landscaping. The best choice depends on your home's structure, land availability, zoning, and budget.
