20-1636 HOUSE PLAN -Coastal Farmhouse House Plan – 2-Bed, 2-Bath, 1,200 SF

Elevated Coastal Farmhouse Carriage House Plan with Low Country Character

A thoughtfully designed Coastal Farmhouse carriage house plan featuring an elevated layout, board and batten exterior, and flexible living space ideal for ADU, guest suite, or garage apartment use.

This Coastal Farmhouse carriage house plan blends classic Low Country architecture with clean Modern Farmhouse detailing to create a timeless yet highly functional small home design. Elevated above grade and anchored by a garage-level foundation, this plan is ideal for coastal regions, flood-prone lots, alley-loaded properties, or homeowners seeking a detached living space with strong architectural presence.

The exterior composition is defined by crisp white board and batten siding, horizontal lap accents, and a dark standing-seam metal roof that reinforces both durability and coastal authenticity. Symmetry, clean rooflines, and carefully proportioned windows give this design a refined, classic look that fits seamlessly into coastal, Southern, and traditional neighborhoods.

Architectural Style Overview

This design is rooted in Coastal Farmhouse architecture, with strong Low Country influences and subtle Modern Farmhouse refinement. The elevated structure, exterior stair access, and simple massing reflect traditional Southern coastal building practices, while the clean finishes and restrained detailing give it a fresh, modern feel.

• Primary Style: Coastal Farmhouse, Low Country
• Secondary Style: Modern Farmhouse

The result is a versatile structure that works equally well as a garage apartment, guest house, rental unit, or private studio—without sacrificing curb appeal or long-term value.

Exterior Materials & Construction

The exterior materials were selected for longevity, weather resistance, and timeless appeal:

• Board and batten siding for vertical emphasis and classic farmhouse character
• Horizontal lap siding accents for visual balance
• Standing-seam metal roof for durability and coastal resilience
• Elevated foundation suitable for flood zones and coastal lots
• Exterior stair access separating garage and living spaces

This combination of materials not only enhances the home’s architectural identity but also reduces long-term maintenance—an important consideration for secondary dwellings and investment properties.

Flexible Garage Apartment Layout

Designed as a true carriage house, this plan places garage and storage space at the lower level while reserving the upper floor for comfortable, private living quarters. This separation makes the home ideal for:

• Accessory Dwelling Units (ADUs)
• Guest suites or extended family housing
• Rental units for passive income
• Home offices or creative studios
• Garage apartments for urban or alley-loaded lots

The exterior staircase provides independent access, enhancing privacy and making the plan especially suitable for rental or multi-generational use.

Interior Living Experience

Inside, the upper-level living space is designed to feel bright, open, and efficient. Windows on multiple elevations allow natural light to flood the interior, reinforcing the coastal aesthetic and creating an inviting atmosphere.

The layout supports a comfortable daily lifestyle while remaining compact and easy to maintain—perfect for homeowners who want flexibility without excess square footage.

Bedrooms & Bathrooms

• 2 well-proportioned bedrooms suitable for guests, tenants, or family members
• 2 full bathrooms designed for privacy and convenience
• Efficient circulation minimizes wasted space

This configuration allows the plan to function as a full-time residence, short-term rental, or luxury guest house.

Coastal & Low Country Design Benefits

Low Country architecture has been refined over generations to respond to climate, airflow, and site conditions. This carriage house plan incorporates those principles through its elevated structure, shaded access points, and balanced proportions.

According to architectural research on coastal housing design published by ArchDaily, elevated structures with durable materials and simple forms consistently outperform more complex designs in coastal environments—both structurally and visually.

Ideal Lot Applications

This Coastal Farmhouse carriage house plan is especially well suited for:

• Coastal and flood-zone properties
• Alley-loaded or rear-access lots
• Narrow urban parcels
• Estate properties requiring detached guest housing
• Vacation homes needing rental flexibility

The compact footprint and vertical organization make it easy to integrate into existing properties without overwhelming the main residence.

Why Choose a Carriage House or ADU Plan?

Carriage houses and ADUs are increasingly popular due to their versatility and return on investment. This plan allows homeowners to:

• Generate rental income
• Provide private housing for family members
• Add long-term property value
• Create flexible work-from-home or studio space

Because the design includes a full residential layout above the garage, it offers far more functionality than a simple outbuilding—while maintaining a refined architectural presence.

Included with This House Plan

• CAD Files: Fully editable drawings for customization
• PDF Construction Set: Permit-ready and builder-friendly
• Unlimited Build License: Build as many times as you want
• Professionally Designed Plans: Created for real-world construction
