This stately house plan was inspired by a historical Nashville home. It features four fireplaces, a three-story foyer, and four covered porches. While the existing plan features a total of 6,265 heated square feet, you can add the Bluebird Cottage Plan 2026 to the property to complete the estate and add a designated space to accommodate guests or family members.

Each of our in-law suite home designs has accommodations for long-term guests like a private bedroom suite or even a full apartment alongside the house plan's main floor plan.

We design all kinds of house plans with attached guest houses and in-law suites, so take a look no matter what you have in mind.

As the population ages, more families will become caretakers for elderly parents or relatives. These house plans with in-law suites offer the needed space (often on the first floor, ideal for a person with limited mobility). Of course, in-law suites can be used by buyers in many different situations, from owners who simply want comfortable guest accommodations to those with nannies or live-in caretakers. The suites themselves range from a simple bedroom and bathroom to more elaborate apartments suitable for semi-independent living (older children, perhaps returned from college and looking for a job, will especially appreciate the latter type). Some of these suites are even detached for the home for greater privacy. Either way, a house plan with an in-law suite offers outstanding versatility for the future. Adding onto an existing home?
