Coastal Low Country House Plan with Elevated Living, Deep Porches & Southern Character

A 2,607 sq. ft. Coastal Low Country home offering five bedrooms, five baths, classic Southern proportions, and construction-ready CAD + PDF plans with unlimited build license.

This Coastal Low Country house plan captures the relaxed elegance of Southern coastal architecture while delivering modern livability and long-term durability. Designed for warm climates, waterfront settings, and elevated lot conditions, the home blends timeless proportions with practical planning that supports everyday comfort, entertaining, and multigenerational use.

The exterior showcases horizontal lap siding paired with crisp trim, tall windows, and generous porches that wrap the home in shade and outdoor living space. A raised foundation not only enhances curb appeal but also improves ventilation and flood resilience—an essential feature for coastal and Low Country regions. The result is a home that feels rooted in tradition while functioning seamlessly for contemporary lifestyles.

Architectural Style & Exterior Design

This design is firmly grounded in Coastal and Southern / Low Country architecture. Hallmark elements include:

• Elevated main living level for airflow and coastal compliance
• Wide front porch with classic railings and welcoming stair approach
• Balanced façade with vertically proportioned windows
• Lap siding exterior suited for humid and salt-air environments
• Detached or offset garage placement for traditional neighborhood appeal

The architectural massing emphasizes symmetry, depth, and livable outdoor zones—key traits of Charleston and Low Country–inspired homes.

Floor Plan Overview

Heated & Outdoor Living Areas

• Total Heated Area: 2,607 square feet
• Bedrooms: 5
• Bathrooms: 5
• Outdoor Spaces: Covered porches, screened porch, and shaded entry zones

The layout prioritizes cross-ventilation, privacy, and flexibility, making it equally suitable as a primary residence, vacation home, or luxury coastal rental.

Main Level Living & Entertaining

The main living level is elevated above grade and organized around a central open-concept core. The great room, kitchen, and dining area flow together naturally, creating a social heart that opens directly onto outdoor living spaces.

Large windows and porch doors invite in natural light while maintaining shaded interiors—an essential balance for coastal comfort. The great room is proportioned to accommodate built-ins and a fireplace feature wall, while the dining area enjoys easy access to the porch for indoor-outdoor meals.

Kitchen Design & Storage

• Central island for prep, seating, and gathering
• Efficient work triangle for everyday cooking
• Generous pantry storage
• Optional upgrades for scullery or extended cabinetry

The kitchen is designed to support both casual daily use and larger gatherings, making it ideal for coastal entertaining.

Primary Suite Retreat

The primary suite is positioned for privacy and comfort, with the potential for elevated views and enhanced airflow. Tall ceilings and generous window placement reinforce the airy, resort-like feel associated with Coastal Low Country homes.

• Spacious walk-in closet
• Primary bath with double vanity layout options
• Walk-in shower and optional freestanding tub
• Direct or nearby access to porch or balcony space

Secondary Bedrooms & Guest Flexibility

Four additional bedrooms are thoughtfully distributed to support family living, guest stays, or short-term rental use. Each bedroom is sized for standard furnishings and includes convenient access to a full bath.

This flexibility makes the plan especially attractive for coastal destinations where guest accommodations are a priority.

Office, Flex & Lifestyle Spaces

A dedicated flex space or office allows the home to adapt to modern work-from-home needs. This room can also function as a hobby space, library, or additional guest retreat depending on household requirements.

Outdoor Living the Low Country Way

Outdoor living is central to this design. Deep porches provide shade and comfort throughout the day, while screened areas extend usability into the evening hours. These spaces are ideal for:

• Outdoor dining and entertaining
• Relaxed seating and reading areas
• Coastal breezes without direct sun exposure
• Seasonal sleeping porch adaptations

Materials, Construction & Durability

The exterior lap siding is selected for durability, classic appearance, and compatibility with coastal climates. When paired with proper weather barriers and ventilation strategies, this material performs exceptionally well in humid and salt-air environments.

• Elevated foundation options for flood-prone zones
• Straightforward rooflines for weather resistance
• Porch overhangs that protect walls and openings
• Compatibility with hurricane-rated window systems
