Things change. Anyone buying a new home is essentially guessing the amount of space they'll need for now and the foreseeable future. But foreseeable is the important word here; life may have other plans with unexpected newcomers to the household such as an elderly parent who needs care, a grown child moving back in after college, or perhaps some rambunctious new pets. And then there's the never-ending need for storage.

In other words, it's best to plan for the unexpected. These house plans feature most of the living space on the first floor (allowing for accessibility and easier aging in place) but also include spacious flex areas on the second level.

Plentiful Bedrooms + Bonus Space

With five bedrooms on one level, this 3,311-square-foot home accommodates a big and busy family now and for years to come. Additionally, an office on the main level and a large bonus space (with a full bathroom, walk-in closet, and generous dimensions) upstairs allow for even more people, such as during the holidays. Naturally, a large laundry room takes on great importance in a large household, and this one delivers – in fact, it even connects to the master suite for extra convenience. When owners want to relax, they can escape to their modern bathroom (check out the huge shower). See more images, information, and the floor plans.

Suite and Loft for Visitors to Lounge

Three of this home’s four bedrooms sit on the main level, so there won’t be a lot of trekking up and down stairs. French doors (two sets of them, actually) open up the vaulted family room to the fireplace-warmed porch in back. Barn doors in the study add extra farmhouse flair to match the sleek exterior. Guests coming? They’ll love the spacious suite and loft upstairs. Unfinished space over the garage adds storage potential. See more images, information, and the floor plans.

Flexible Lair Upstairs

This 2,187-square-foot design captures your attention with sleek vertical siding and warm Craftsman-like details. Inside, the remarkably versatile layout puts most living spaces on the main floor, plus an optional fourth bedroom and bonus space upstairs that can be used as a private living zone by visitors or perhaps a young adult. The vaulted family room flows into the island kitchen and out to the impressive back porches. In the master suite, owners will find relaxation in their private oasis-like bathroom. See more images, information, and the floor plans.

Organized and Relaxing

Four bedrooms fit nicely on the first floor of this 2,487-square-foot plan, with a 23 x 23 bonus room available to finish upstairs if more room is needed. Family-friendly touches include a mudroom with lockers and a large pantry, with the laundry room just steps away (but not in the way when entering from the three-car garage). A double-headed shower adds contemporary luxury to the master suite. Graceful tapered columns highlight the entrance on the exterior. See more images, information, and the floor plans.
