Coastal Contemporary House Plan with Split Bedroom Design

Exterior & Curb Appeal

This coastal contemporary house design blends modern lines with warm, inviting finishes. The exterior features a mix of stone and smooth stucco textures, low-pitched hip roofs, and broad overhangs that enhance the home’s tropical feel. Large windows welcome natural light inside while giving the façade a sleek, balanced look. The central covered entry, framed by stone accents, establishes a bold focal point and offers a stylish welcome for family and guests.

Porches & Outdoor Living

Outdoor living is at the heart of this home. At the back, a 16’8” by 12’8” covered lanai provides shaded relaxation space, seamlessly connecting the indoor great room to the backyard. Adjacent to it, an outdoor kitchen (11’4” by 18’) is perfectly designed for alfresco dining and entertaining. Whether for hosting parties, poolside lounging, or enjoying quiet evenings, this home offers a coastal lifestyle that prioritizes the outdoors.

Main Floor Layout

The foyer opens into a spacious great room measuring 17’ by 19’, where tall ceilings and open sightlines create a sense of grandeur. This central hub connects effortlessly to the dining room (16’8” by 12’) and the kitchen (16’8” by 17’), which is equipped with a large center island, walk-in pantry (10’ by 9’), and plenty of counter space. The open-concept flow ensures both functionality and a welcoming environment for everyday living and entertaining.

Bedrooms & Bathrooms

The home features a split-bedroom design for privacy and comfort. The master suite, located on the left wing, is generously sized at 15’4” by 19’4”. It includes dual walk-in closets and a spa-like master bath with a large walk-in shower, double vanities, and a soaking tub. On the opposite wing, three additional bedrooms provide family or guest accommodations. Bedroom 2 (12’ by 12’), Bedroom 3 (13’ by 11’8”), and Bedroom 4 (15’ by 11’8”) share two full bathrooms, ensuring convenience for larger households or visitors.

Additional Spaces

This house also includes a private study (12’ by 12’) located near the master suite, perfect for remote work or a quiet retreat. A mudroom connects the living area to the dual garages—Garage 1 at 22’ by 23’4” and Garage 2 at 19’4” by 15’4”—offering abundant parking and storage. The large laundry room (14’8” by 10’) with built-in cabinetry makes daily chores more efficient and organized.

Lifestyle & Comfort

Designed for families who enjoy both relaxation and entertaining, this home’s layout balances open living areas with private retreats. The split-bedroom design enhances privacy, while the large lanai and outdoor kitchen extend living space into the fresh air. Its coastal contemporary aesthetic makes it equally suited for beachside living, suburban communities, or warm-weather retreats.
