Exterior Design
This charming cottage-style ADU offers **750 sq ft** of living space in a single story, framed with durable **2×6 exterior walls**. It features a **6-foot-deep covered porch** across the front facade (≈ 78 sq ft), centered around the front door, providing shelter and curb appeal. The roof includes trusses, with a primary pitch of **6.5:12** and a secondary pitch of **11:12**, giving balanced proportions and good pitch variety.
Measuring **30′ wide × 31′ deep**, the structure has a modest ridge height of **16′**, and first-floor ceilings are 9 feet—making the proportions feel open without inflating cost.
Interior Layout
Inside, the living room and kitchen share an open floor plan in the front of the home. There’s room for an island and even a small table to sit and gather.
Bedrooms run along the left side of the house, each with “linear” closets—space-saving, simple, and functional. The shared bathroom is located at the back of the plan, along with a utility room that houses a stacked laundry setup.
Floor Plan:
Bedrooms & Bathrooms
There are **2 bedrooms** and **1 full bathroom**. Given the compact size, both bedrooms are well sized with efficient layouts. The shared bathroom serves both bedrooms and common areas.
Living & Dining Spaces
The open layout connecting the kitchen and living room in the front maximizes usable space. With front windows and the porch, there’s enough light to avoid feeling closed in.
Because the dining space is essentially part of the kitchen/living core, it encourages interaction and makes small-footprint living feel communal rather than cramped.
Kitchen Features
The kitchen has an island (size modest) that supports both meal prep and casual dining. Counters and fixtures are laid out efficiently. There’s clever integration of utility near the rear of the house.
Outdoor Living (porch, deck, patio, etc.)
The 6-foot-deep covered porch at the front gives you a usable outdoor space sheltered from sun and rain. It’s enough for a couple of chairs, a mat, or plants—nice for entry or morning brewing of coffee.
Garage & Storage
This plan does **not** include a garage. Storage is managed via bedroom closets, kitchen cabinets, and the utility room. Because the overall footprint is modest, space-saving storage choices are key.
Bonus/Expansion Rooms
There is no dedicated bonus room, but the compact layout, steep roof pitches, and attic volume suggest possible attic storage or even conversion (if allowed by code). Exterior modifications, like a small deck or enclosed porch, could also expand usable space without disrupting the core plan.
Estimated Building Cost
The estimated cost to build this ADU in the United States ranges between $150,000 – $250,000, depending heavily on location, labor, materials, and foundation type. The small size helps keep overall investment lower, though per-sq-ft cost may be higher than larger homes.
In summary, this 2-bed Traditional Cottage ADU offers surprising comfort in a tight package. With its efficient layout, welcoming porch, smart storage, and solid construction, it’s ideal for downsizing, guest housing, or supplemental living—designed to feel roomy where it counts, and cozy everywhere else.
