One-Story House Plan Under 2000 Square Feet with Bonus and Garage Expansion

This smartly laid-out one-story design delivers about 1,995 sq ft of heated living space, with an optional 299 sq ft bonus room above the garage. Featuring 3 bedrooms, 2 bathrooms, and flexible garage options, it balances modest size with opportunity for expansion. 1

Efficient Flow & Natural Gathering Hub

An inviting foyer opens into a vaulted great room (11’6″ tray ceiling) anchored by a fireplace. The open layout connects seamlessly to a semi-formal dining area and the kitchen—perfect for gathering, everyday or special moments. 2

Kitchen Built for Connection

The kitchen features a generous 4′ × 8′ island that seats five and caters well to prep and conversation. A spacious walk-in pantry plus ample cabinetry keeps essentials organized and at hand. 3

Master Suite That Feels Like a Retreat

Tucked privately off the main living space, the master suite comes complete with a tray ceiling, roomy walk-in closet, and dedicated bathroom for total comfort. 4

Guest Bedrooms & Bonus Flex Space

Two additional bedrooms share a full hall bath—clustered for convenience. The optional bonus area over the garage (~299 sq ft) is perfect for future expansion, like a home office or guest quarters. 5

Outdoor Living & Garage Adaptability

A deep 10-foot covered rear porch extends your living outdoors. The attached garage (≈495 sq ft) comes standard in a 2-car layout—with optional upgrades to a 3-car front or side-loading bay, providing flexibility to suit your site or needs. 6

Why This Design Works Twice as Hard

It’s compact yet versatile—built for today’s needs with room to grow. The open core is cozy but airy, the master is private yet connected, and the bonus over the garage gives you options: guest space, office, studio, it’s ready when you are.

Bonus rooms sound fun, but they require thoughtful integration—this plan nails it by offering a seamless optional upgrade, all under that single-roof simplicity.
