Home or residential renovation is an almost $300 billion industry in the United States, and a $48 billion industry in Canada.[full citation needed] The average cost per project is $3,000 in the United States and $11,000–15,000 in Canada.[full citation needed]
Professional home improvement is ancient and goes back to the beginning of recorded civilization. One example is Sergius Orata, who in the 1st century B.C. is said by the writer Vitruvius (in his famous book De architectura) to have invented the hypocaust.
The hypocaust is an underfloor heating system that was used throughout the Roman empire in villas of the wealthy. He is said to have become wealthy himself by buying villas at a low price, adding spas and his newly invented hypocaust, and reselling them at higher prices.
There are several types of companies that contribute to the booming renovation industry. Supply businesses such as Home Depot, Lowe's, Menards and Rona Lansing provide all the materials and tools necessary to facilitate home renovations.
Many online companies and home improvement websites such as Porch and Houzz offer tips, guidelines and trends to give homeowners ideas for design and décor.
