About Mother-in-Law Suite Plans

As its name suggests, these plans came about as a means for allowing the mother-in-law (or other relative) of a couple to move in with them while maintaining a high level of independence. House plans with a mother-in-law suite typically begin with a standard multi-bedroom house plan for the main residence, which can appear in virtually any style. The suite exists as a separate yet attached unit to the main home floor plan, with the specific layout depending on the design for the rest of the building. Some in-law suites exist as a converted basement or bottom floor, with the main family area residing above it. Other floor plan layouts place the suite on the side of the home, typically connected via shared walls or a secondary access way into the main house plan.

Regardless of the general house plan layout, mother-in-law house plans usually include all of the standard amenities of a standalone unit, such as a dedicated bedroom separate from the living space or dining area. The accommodations in mother-in-law suite plans  also include dedicated kitchens, which can range from a space-conscious kitchenette to a fully functioning area with its own stove and cooking area. This type of home plan also includes a dedicated bathroom within the floor plan of the suite, as well as a standalone entryway that leads straight outside rather than requiring the occupant to pass through the main part of the house plan to get into and out of the unit.

Whether you have actual in-laws moving in with you, aging relatives, or an older child who seeks more independence, a mother-in-law suite house plan from The Plan Collection may be just what you’re looking for. Shop now.

The In-Law Suite: Say Hello to a Home-within-the-Home


TPC author Rexy Legaspi
By

The In-Law Suite: Welcome to a Home-Within-the-Home   On an upswing for a number of years, in-law suites have redefined the idea of living together for the modern family. These “homes-within-the-home” are stylish accommodations for in-laws, returning children, or overnight/weekend guests. And, they come in all shapes and sizes - from a garage studio apartment, to a first floor master bedroom, a refinished basement, or a tiny cottage on the grounds of the primary residence.
