15-1713 HOUSE PLAN – Traditional House Plan – 4-Bed, 4-Bath, 3,600 SF

New American Traditional Duplex House Plan with Stone Base & Siding Exterior

This New American traditional duplex house plan is designed to meet the growing demand for flexible, efficient, and visually timeless residential architecture. Blending classic Traditional and Colonial Revival influences with modern suburban planning, this elevated duplex delivers long-term value for homeowners, investors, and multi-generational families alike. Its symmetrical façade, raised garage level, and durable exterior materials create a refined yet approachable presence that fits seamlessly into established neighborhoods and new developments.

With approximately 3,600 heated square feet total, this plan can function as two mirrored residential units or be adapted into a single expansive home. The architectural balance and thoughtful massing ensure that the structure never feels oversized, while still offering generous interior living space.

Architectural Style & Design Character

The primary architectural identity of this home is rooted in New American and Traditional design, reinforced by subtle Colonial Revival symmetry. The evenly spaced windows, centered gables, and proportional rooflines establish a timeless look that resists trend fatigue. This style is particularly popular in suburban and infill developments where long-term resale value and broad market appeal are critical.

Clean lines, restrained ornamentation, and practical detailing allow this home to bridge classic and transitional aesthetics. Builders and homeowners can easily personalize the exterior color palette or trim level without compromising the architectural integrity of the design.

Exterior Materials & Curb Appeal

The exterior is composed of horizontal lap siding paired with a full stone veneer base, a proven combination for both durability and visual grounding. The stone base adds texture and permanence at the lower level, while the siding above lightens the mass of the structure and enhances vertical balance.

• Stone veneer foundation and garage level for strength and visual weight
• Low-maintenance horizontal siding on upper levels
• Symmetrical gabled rooflines for classic curb appeal
• Large, evenly spaced windows for balanced elevation rhythm
• Raised entry staircases that create architectural depth

This exterior material strategy is ideal for regions requiring durable weather resistance while maintaining a refined residential appearance.

Main-Level Living & Interior Layout

Each unit is accessed from its own dedicated front staircase, leading into a bright and open main living level. The layout prioritizes daily usability while preserving separation between public and private spaces.

• Spacious living rooms with ample wall space for furniture layouts
• Open kitchen and dining zones designed for gathering and entertaining
• Efficient circulation paths that minimize wasted square footage
• Dedicated storage areas including closets and pantry zones

The open-concept configuration supports modern living while maintaining enough separation to reduce noise and improve functionality. Builders may easily customize kitchen island sizes, add built-in cabinetry, or adjust room proportions to suit regional buyer preferences.

Upper-Level Bedrooms & Private Spaces

The upper level houses the bedroom suites, creating a private retreat away from daily activity. Depending on configuration, the plan supports four total bedrooms and up to four full bathrooms.

• Comfortably sized bedrooms with generous closet capacity
• Primary suites with ensuite bath potential
• Flexible secondary bedrooms ideal for offices or guest rooms
• Strategic window placement for light and ventilation

This separation of living and sleeping areas improves comfort, privacy, and long-term livability for both owner-occupied and rental scenarios.

Garage Level & Structural Benefits

The ground level incorporates raised garages beneath each unit, an increasingly popular solution in suburban design. This configuration enhances structural efficiency while preserving valuable interior square footage.

• Protected vehicle parking below living spaces
• Improved drainage and moisture protection
• Additional storage beneath stairwells
• Elevated main floor for enhanced street presence

The raised foundation also improves adaptability for sloped lots and regions requiring flood mitigation strategies.

Energy Efficiency & Build Performance

This home plan is engineered to support modern energy-efficiency standards and regional building codes.

• Optimized window layouts to maximize daylight
• Roof geometry designed for efficient water shedding
• Durable siding and stone materials for long service life
• Compatibility with upgraded insulation and HVAC systems

These features help reduce operating costs while increasing long-term homeowner satisfaction.

Customization & Flexibility

One of the strongest advantages of this New American duplex plan is its adaptability.

• Convert duplex into a single large residence
• Reconfigure interior walls for office or flex spaces
• Upgrade bathrooms to luxury ensuite layouts
• Add covered porches or outdoor living areas
• Modify garage usage for workshops or storage

This flexibility allows the home to evolve alongside changing lifestyle needs.
