Compact Yet Inviting Exterior Design
The exterior presents a simple, clean façade suited to both suburban and infill settings. This single-level duplex uses a balanced roofline and symmetrical layout that gives each unit its own entrance while maintaining a cohesive architectural presence. 1 Designed to fit comfortably on a modest lot, the width and depth (approximately 22′ wide × 35′ deep per unit) keep each unit compact without sacrificing usability or comfort. 2
Easy care materials and straightforward detailing help this plan feel approachable and timeless, inviting occupants and visitors alike without overwhelming its surroundings. 3
Open Interiors with Smart Use of Space
Entering either unit, you’re greeted by a living space that’s thoughtfully arranged for everyday living. The open feel makes the most of the modest square footage, giving each area a comfortable sense of space and flow. 4 Although compact, the interiors are laid out to avoid wasted circulation area, focusing instead on practical connections between living, kitchen, and sleeping zones. 5
Windows throughout each unit bring in daylight, helping the interior feel brighter and larger than its footprint might suggest, and reinforcing a welcoming, efficient ambiance. 6
Living & Dining — Efficient and Functional
The living room is positioned to be the primary gathering point for each unit. Its design supports flexible furniture arrangements, making it easy to optimize space whether you’re watching TV, reading, or simply relaxing. 7
Nearby, the dining area and kitchen connect naturally, encouraging easy transitions between meal prep and everyday living. The kitchen zone is positioned to provide essential counter space and storage while maintaining an open feel to the rest of the unit. 8
Kitchen Designed for Everyday Living
Each unit’s kitchen is compact yet practical, with a layout that supports efficient meal preparation and storage. Although modest in size, the design maximizes available surfaces, allowing for everyday routines to run smoothly. 9 The close relationship between kitchen, dining, and living areas means you’re always part of the action while cooking or entertaining. 10
Bedrooms — Comfort in Compact Scale
Each of the three bedrooms per unit is thoughtfully sized to provide comfort without unnecessary extra space. These rooms are well suited for everyday sleeping arrangements, home offices, guest rooms, or flexible use depending on household needs. 11
The bedroom layout is practical and efficient, making these units suitable for families, roommates, or extended stay guests. 12
Bathroom — Central & Accessible
A single full bathroom in each unit is positioned for convenient access from both living and bedroom areas. While compact, the bathroom is functional and designed for everyday routines. 13
Its placement supports privacy while still keeping walkways simple and efficient. 14
Storage & Practical Details
Despite its efficient footprint, this plan incorporates storage opportunities and practical layout elements that enhance livability. Small closets, strategic cabinetry, and thoughtful wall placement help maintain an organized interior without crowding usable space. 15
