40' x 25' Modern Timber Frame Cottage House Plan with 2 Bedrooms

A Modern Twin Gable Cottage Designed for Real Life

This 1,000 sq ft single-story modern cottage house plan proves that a small footprint can live large. Two pitched gable wings anchor each end of the home, each holding a private master-sized bedroom with its own en-suite bath — a rare layout that works beautifully for guests, roommates, rental income, or multigenerational living. Between the wings, an open living room and galley kitchen flow directly onto a sheltered covered deck framed by the twin gables, creating a stunning indoor-outdoor living space.

Who This Plan Is For
