As housing prices continue to climb in Toronto and the Greater Toronto Area (GTA), many homeowners are exploring ways to make their properties more valuable and functional. One popular option is converting a single-family home into a legal duplex. This transformation can provide steady rental income, accommodate extended family, and boost your property's market value. But turning your home into a legal duplex involves more than just adding a second kitchen.

Choosing between a custom home builder and a production builder is one of the most important decisions when building a new home. While production builders offer standardized designs and faster timelines, custom home builders provide complete design flexibility, personalized layouts, premium finishes, and greater long-term value. Learn which option is right for your lifestyle, budget, and goals.
