Select a Plan Designed for Your Lot

The Overlook

Introducing Mode Homes' 2,084 SQFT Traditional plan, The Overlook. A 4-bedroom, 2.5-bath build-on-your-lot home that blends classic exterior materials — lap siding, wood garage doors, and brick — with a smart, modern interior layout. The standout feature: a main-floor master suite, with three additional bedrooms upstairs. The Overlook is the plan for buyers who want single-level primary living with room above for kids, guests, or aging-in-place flexibility built right in.

The Crestline

Introducing Mode Homes' 2,231 SQFT Modern Farmhouse plan, The Crestline. A 4-bedroom, 2.5-bath build-on-your-lot home that takes the farmhouse favorite and gives it a modern edge — clean lines, a great room built around the view, and a layout that works as well in a Boise infill neighborhood as it does on a five-acre parcel. The Crestline is the plan for families who want classic curb appeal up front and a smart, livable floor plan behind the door.

The Trailhead

Introducing Mode Homes' 2,376 SQFT Modern Farmhouse plan, The Trailhead. A 4-bedroom, 3-bath build-on-your-lot home 321 SF bonus room, dedicated office, guest suite, and shop space — built for the way Boise families actually live, work, and store their gear. The Trailhead is the plan for buyers who want a real home base: room for a growing family, space to work from home, a spot for the in-laws, and somewhere to put the trailer, the tools, and the toys.

The Timberline

Introducing Mode Homes' 2,077 SQFT Modern Farmhouse plan, The Timberline. A 3-4 bedroom, 2.5 bath build-on-your-lot home designed around how families actually move through the day — open shared spaces on the main floor, private bedrooms upstairs, and the small details that make daily life work. From the drop zone off the garage to the pocket office tucked away for focused work, The Timberline is built for real Boise families who want a true forever home.

The Summit

Introducing Mode Homes' 1,760 SQFT 2-story plan, The Summit. A New American design built for build-on-your-lot families who want curb appeal up front and a real home behind the door. Three bedrooms, two and a half bathrooms, and a layout that puts the family room at the heart of the main floor — anchored by a fireplace, framed by built-in bookshelves, and opened up by a kitchen designed for the way Boise families actually live.

The Stanley

Introducing Mode Homes' 900 SQFT 2-Story ADU plan, The Stanley. This is the plan that lives like a single-family home. Two full bedrooms, one and a half bathrooms, full-size appliances, and a narrow footprint built to fit challenging Boise infill lots. The kind of ADU that feels less like a backyard cottage and more like a real home.
