    Bring all your generations under one roof and build multigenerational house plans by yourself.

    These days, multi-family homes are becoming increasingly more popular. As kids come home from college and live with their parents while they get on their feet, or aging relatives come to live with the younger generation, or even brothers and sisters raise their families under the same room, multigenerational house plans have become even more common for these various living arrangements. There are many different ways to accommodate a large number of adults living under one roof, and most of these types of homes offer a great value for families who want to stay together and save money. If you are considering your options for building a home that can fit multiple generations of family members, read on for more information about the types of dwellings you’ll find and which one might be right for you and your family.

    Types of Multigenerational House Plans

    A single-family home typically has one kitchen, a few bathrooms, and a few bedrooms. With multigenerational house plans, there are a few ways that more family members can be accommodated. These include:

    • By building house plans with separate living quarters, you could have a duplex where two families live on two house sides. This offers the security of the home being connected. Also, the privacy that comes with both sides having their own bathrooms and kitchens. Duplexes are a great option for those who want to be close to family while still maintaining some autonomy.

    • Guests houses are a good option if some family members want more privacy on the same property. In some instances, guest houses will be fully equipped with bathrooms and a kitchen. In others, the guest house may just have a living space and a bathroom. Either way, the house is not attached to the main house. So those who are living in it will feel like they have a bit more privacy.

    • Mother-in-law suite is a great option for those families who have older generations living with them. These elderly family members will have their own bedroom, living area, and bathroom. Also, they will still be in the home with the rest of the family. If they need help, they will be able to get it easily.

    Another option not mentioned yet are extended family house plans. This type of plans might have multiple kitchens, and often multiple master bedrooms. This allows family members to live in one main house but still have their separate space. Many adults can live in this type of home, without feeling like they are stepping on each other.

    When it comes to building multigenerational house plans, costs can vary. Adding on an in-law suite is not very expensive, but building an entire guest house can be. There are heating and cooling costs to consider, as well as electricity. But, what many find is that in a multi-generation home, there are more adults that are able to contribute to the monthly costs. Everything does not fall on one head of the household. In fact, everyone can share the load and reduce the expenses greatly. Plus, the time spent together and meals shared can be far more valuable than the cost of the home.

    If you have extra family members living with you and you want to build a space for everyone, consider multi generational house plans.
