Dual Living House Plans Perth
Dual Living House Plans Perth Families and Investors Trust
Sovereign Building Company designs and builds custom dual-living house plans in Perth to meet the evolving needs of families, downsizers, and investors. Our dual-key homes offer two self-contained living areas under one roof, each with an entrance, kitchen, bathroom, and living space. Whether you’re housing elderly parents, growing teenagers, or tenants, our designs maximize independence, privacy, and value. From the street, these homes look like a single stylish residence, but inside, they deliver flexible, multi-purpose functionality. We build smarter by offering dual key designs that remove the need for costly granny flat extensions or significant renovations.


Our dual-living house plans are also ideal for investors looking to increase rental yield or resale value. We provide a free project feasibility study so that you can assess your block and budget before building. With our Walk Thru Floor Plans, you can even experience your new home at full scale before construction begins.
