L-Shaped Cottage House Plan - 3 Bed, 2 Bath, 1,360 Sq Ft

Modern L-Shaped Cottage House Plan - 3 Bed, 2 Bath, 1,360 Sq Ft of Smart Single-Story Living

Looking for a small house plan that lives large? This modern L-shaped cottage combines an efficient 1,360 sq ft single-story layout with a dramatic 21'11" x 11'11" pergola-covered terrace, giving you resort-style indoor-outdoor living on a compact 40'1" x 34'2" footprint. It is a perfect fit for owner builders, backyard guest houses, ADUs, short-term rental investments, lake or country lots, and anyone downsizing without giving up comfort.

Why builders and homeowners love this layout

The L-shape does the heavy lifting. The private wing holds a generous 15'4" x 11'8" master bedroom with its own bath featuring a soaking tub, while bedrooms 2 and 3 (each 10'4" x 7'6") share a full hall bath on the opposite side of the open living zone. In between, the 13'5" x 15'4" living room flows into a 15'4" x 9'8" kitchen with dining nook, and a dedicated 5'0" x 5'8" laundry room keeps the washer and dryer out of sight. Everything sits on one level with no stairs, which makes this plan excellent for aging in place and accessible living.
