Select a Plan Designed for Your Lot

The Creekside

Introducing Mode Homes’ 960 SQFT ADU plan, The Creekside. This is the plan that fits more home on less lot. Three bedrooms, two full bathrooms, and upstairs laundry — all in a two-story footprint built for Boise's tightest infill sites. Ideal for families, multigenerational living, or premium rental income.

The Meadow

Introducing Mode Homes’ 1,000 SQFT ADU plan, The Meadow. This is the plan that lives bigger than it looks. Three bedrooms, two full bathrooms, and an open layout that puts everything you need on one level. Built for Boise families, multigenerational living, or premium rental income.

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.
