Duplex house plans & semi-detached house plans

Browse through our fine selection of duplex house plans and semi-detached house plans available in a number of styles and for all budgets. Multi-unit homes are an attractive option to optimize land usage and reduce construction costs to make housing more affordable. In the past, these homes have been popular for first time homeowners but they are also gaining popularity for baby boomers, housing for extended family, and for investment purposes. Crunch the numbers and you may find that a good portion of your mortgage can be covered by renting the second unit!
