Modern Farmhouse Plan Under 3700 Square Feet Including an In-Law Suite

This expansive modern farmhouse blends multi-generational flexibility with modern design elegance. Boasting approximately **3,686 sq ft**, it includes a private in-law suite, two-story great room, angled courtyard garage, and a versatile bonus loft above—everything you need for today and tomorrow. 1

Smart Layout & Inviting Flow

The foyer opens to a dramatic two-story great room anchored by a cozy fireplace, with French doors that lead to a vaulted porch—perfect for indoor-outdoor living. 2

Kitchen & Dining Designed for Connection

A chef’s dream with a large island, seamless flow to dining and great room, plus a massive 7’×15.5′ walk-in pantry accessible from both kitchen and mudroom—ideal for groceries and entertaining with ease. 3

Master Suite & In-Law Wing

The master suite features generous space and privacy, while the separate in-law suite—complete with kitchen, porch access, and shared two-sided fireplace—functions like a self-contained retreat for guests or extended family. 4

Bonus Loft Space

Above the angled three-car garage sits a **639 sq ft bonus loft**—perfect as a media room, studio, or future expansion. 5

Why This Plan Stands Out

Its thoughtful layout offers privacy and togetherness in equal measure. With integrated in-law living, soaring communal spaces, a flexible loft, and timeless farmhouse styling, this plan supports lifestyle now and adaptability for the future.

What Reddit Users Say

The beauty of the façade catches praise—but in forums, some raise valid concerns:

“Kitchen and great room have windows only on one side… lack of natural light… a cave-like feeling.”
“Laundry is so far from the bedrooms… a chore to haul clothes.”
“It is a very long hike from the garage to the pantry for groceries coming in.” 7

These insights can be handy when considering layout tweaks—like adding windows, relocating mudroom access, or adjusting flow to reduce long transitions.
