Split-Bedroom Modern Farmhouse — ~3,346 Sq Ft with 3-Car Garage & Bonus Expansion

This modern farmhouse plan spans about 3,346 sq ft on the main floor, featuring 4 bedrooms, between 2½ and 3½ baths depending on finish choices, a 3-car side-entry garage, and a large bonus room above the garage (~734 sq ft) for expansion. With classic farmhouse aesthetics fused with thoughtful layout, it’s built for today and tomorrow.

Front & Exterior Character

The exterior delivers serious curb appeal: board-and-batten siding, a centered gabled dormer over French doors, and a welcoming front porch that’s 8′-4″ deep. Gables flank the porch, adding charm without excess. 1

Open Living Flow & Gathering Spaces

Enter through the foyer into a vaulted great room that features a fireplace flanked by built-ins.

The great room opens via a 16′ slider to the rear porch—complete with outdoor fireplace and kitchen. Views connect from the front through the back.

The adjacent gourmet kitchen includes a walk-in pantry and oversized prep island. There’s also a formal dining room with an 11′ tray ceiling.

Private Retreats & Split Layout

The master suite is tucked to one side for privacy, with vaulted ceilings, outdoor access, a spacious bathroom with separate tub & shower, and a generous walk-in closet.

On the opposite wing are three secondary bedrooms, each with its own bath (or shared hall bath depending on finish). Bedroom #2 is easily convertible to a home office if needed.

Garage, Mud, & Bonus Expansion

The side-entry 3-car garage includes a storage closet and connects to the mudroom with back-yard access.

Above the garage is a 734 sq ft bonus room with bath—perfect for a media room, guest suite, or studio. Porch space is generous: ~1,308 sq ft combined front and rear.

Estimated U.S. Build Cost (USD)

Modern farmhouses of this scale and with these features generally build in the range of $175-$260 per sq ft in the U.S., depending on finish level, region, and site prep.

That suggests a construction cost from approximately **$585,000-$870,000 USD**, noting the bonus room and high-end exterior touches can push costs up. Land, permitting, and site work are extra.

Why This Plan Might Be the One

Because it combines flexibility with farm-style warmth: strong curb appeal, generous outdoor connection, smart room separation, and future expansion via the bonus. Whether you want family friendly flow, room to host, or evolving workspace, this layout offers “grow-with-you” potential without starting from scratch.
