The Design Concept Overview

Linea House is a two-bedroom ADU concept built around the idea that a compact backyard home should feel like a real home, not a reduced version of one. It sits on a single-storey 9m × 7.1m footprint and is designed for everyday living rather than occasional use, with enough space for a couple, a small family, or a multigenerational arrangement where independent accommodation matters.

The exterior takes a deliberate approach: a clean rectangular form, white horizontal cladding, and dark-framed glazing that reads as calm and contemporary without drawing attention to itself. It's a home that fits naturally into a residential backyard rather than competing with the main dwelling for visual presence. A natural timber deck connects the front of the home to the garden and creates a transition zone between inside and out.

Inside, the palette is warm and settled: oak flooring throughout, white flat-panel cabinetry, marble-look surfaces in the kitchen and bathroom, and a consistent set of black accents across frames, fixtures, and hardware. The open-plan front zone keeps the kitchen, dining, and living areas connected and light-filled. Two bedrooms and the bathroom sit quietly toward the rear. A vertical timber slat screen between the dining and living areas adds texture and a sense of separation without closing either space off.

Here's what defines the design:

• Open-plan layout connecting kitchen, dining, and living toward the front

• Vertical timber slat screen creating a soft visual divide between dining and living zones

• Generous glazing on all elevations bringing natural light into every room

• Integrated storage throughout both bedrooms and the kitchen

• Consistent palette of oak, white, marble-look surfaces, and black accents

It's a design that's practical to live in and easy to understand as a concept, which makes it useful both for homeowners exploring ADU design ideas and for builders considering a marketable two-bedroom model. Tiny Easy's software for ADU builders is built around the design, visualisation, and proposal workflow that makes concepts like this easier to develop and present.

Exterior Design | A Modern Two-Bedroom ADU for the Backyard

The Linea House exterior is built on a single horizontal principle: keep it simple, keep it light, and make sure it belongs in a backyard.

White horizontal weatherboard cladding runs the full perimeter of the home, giving it a clean profile that reads well from the garden and doesn't visually overpower a residential lot. The dark charcoal standing seam roof sits above it with a low-pitch skillion form that keeps the overall height in proportion with the footprint. It's a two-tone palette that reads as a modern ADU exterior without trying too hard.

Key exterior features include:

• White horizontal cladding across all four elevations

• Dark charcoal standing seam roof with a low-pitch skillion profile

• Black-framed windows and sliding doors distributed generously across all visible sides

• Natural timber deck running the full front width, stepping down to the lawn

• Garden-facing glazing creating a clear visual connection from outside to the warm interior

The front facade opens almost entirely to the garden through large sliding or bi-fold doors, while the side walls carry a mix of picture windows and fixed glazing that bring natural light into the rear rooms. You can see the oak flooring and white walls from the garden before you step inside. The timber deck is a generous outdoor zone that works as a seated area, an extension of the living space, and a visual anchor point between the building and the planting beds around it. It's an exterior that belongs in a residential backyard without drawing unnecessary attention to itself, which matters for a two-bedroom ADU designed for everyday suburban use.

Interior | Kitchen & Dining

The kitchen is the most space-efficient room in the Linea House and one of the most carefully considered. It's laid out in a U-shape with a breakfast bar peninsula that creates two distinct zones within the same footprint: one side for preparation and cooking, the other for casual seating.

White flat-panel cabinetry with black bar handles runs the length of the main wall, including a tall pantry tower at one end that provides substantial storage without needing extra furniture. The benchtop on the main cabinet run uses a marble-look surface that carries through to the splashback above, a single material story that keeps the kitchen feeling clean and cohesive. On the peninsula side, the benchtop transitions to a warm timber surface, adding contrast and texture against the white cabinetry.

Two timber bar stools sit at the peninsula, providing an informal alternative to the dining table for morning coffee or a quick meal. There are multiple black-framed windows above the kitchen area facing the garden, so it's one of the best-lit spaces in the home. The oven and appliances are built into the cabinetry to keep the surfaces clear and the layout uncluttered.

The dining zone sits immediately off the kitchen, anchored by a round oak dining table and four white upholstered chairs. A vertical timber slat screen, full ceiling height, built from warm natural timber battens, rises directly behind the dining table and marks the point where dining ends and the living area begins. It's the most distinctive interior feature in this ADU design. The screen creates visual separation and adds texture to the open plan without using walls or losing the sense of connected space. A drum pendant light in dark charcoal hangs above the table, and floating timber shelves on the adjacent wall carry ceramics and plants that keep the zone feeling warm and lived in.

Interior | Living

The living area is positioned at the front of the open-plan zone, directly connected to the dining space and the deck beyond. It's an open, light-filled room that benefits from the natural light entering from both the garden-facing doors and the large picture window on the side wall.

That window is the focal point of the living room. It's a large, square, black-framed opening that takes up most of one wall and frames the garden directly, greenery and outdoor planting visible from the sofa at eye level. The effect is that the garden becomes part of the interior atmosphere rather than something separate. On a bright day, the living area is flooded with natural light; on a quieter evening, it offers a calm, settled view out to the yard.

The furniture arrangement keeps the space open and uncluttered. A warm brown sectional sofa faces the garden window and anchors the seating zone. A round white coffee table with black legs sits on a textured grey rug, and a wall-mounted white floating unit carries the television on the opposite wall. Floating timber shelves run along one wall at mid height, styled with a mix of books, framed art, and indoor plants, including a fiddle leaf fig that reinforces the connection to the natural palette used throughout the home.

Large sliding doors at the front of the living area open to the timber deck, blurring the line between inside and outside when the weather allows. For an ADU designed around everyday backyard living, this indoor-outdoor connection is central to how the space actually works.

Interior | Bathroom

The Linea House bathroom is compact but well-resolved, and it's notably brighter than its footprint might suggest. That brightness comes directly from a black-framed window positioned above the vanity, facing the garden. It's the first thing you see when you walk in: natural light and a view of outdoor planting rather than a wall.

The walk-in shower sits along one side of the bathroom, enclosed by a black-framed glass screen. The shower walls are finished in large-format marble-look tiles, the same material logic as the kitchen, carried through to give the home a consistent material story. Black fittings are used throughout: a rain showerhead, a hand shower, a wall-mounted shelf bracket, and the hardware on the screen frame. The floor tiles are a lighter large-format stone tone that keeps the floor from feeling heavy.

At the vanity, a round white vessel basin sits on a marble-look benchtop above a wall-mounted white cabinet. The tapware is wall-mounted and matte black, consistent with the fixture palette used elsewhere in the bathroom. A round black-framed mirror hangs above the basin, and beside it, a vertical oak timber feature panel adds warmth against the predominantly white and marble-tone surfaces. A white tongue-and-groove feature panel runs along the wall beside the vanity, adding subtle texture without introducing another material.

The bathroom also integrates a washing machine and laundry storage within the cabinetry, a practical decision for a two-bedroom ADU where a separate laundry room isn't part of the footprint.

Interior | Bedroom One

The first bedroom is calm, private, and well-lit without feeling exposed. There are two black-framed windows: a tall, near-floor-to-ceiling opening on one side wall and a smaller window on the adjacent wall. They bring natural light into the room from two directions without putting the bed in direct outdoor sight-lines.

An oak timber bed frame with warm earthy bedding in mocha and terracotta tones sits against the main wall. The bedding palette is consistent with the rest of the interior, warm, natural, and understated rather than bright or decorative. A small timber side table with a plant beside the bed completes the furniture arrangement without crowding the room.

Storage is built in and generous. A white flat-panel wardrobe with black bar handles runs floor to ceiling on one side of the room, and immediately beside it, an integrated open shelving unit in warm oak provides a place for books, objects, and personal items without requiring freestanding furniture. Together, the wardrobe and shelving unit occupy one full wall without making the room feel reduced, they're intentional rather than afterthought storage.

The overall ceiling height (3.2m / 10.4ft), consistent throughout the home, gives the bedroom a spaciousness that the floor dimensions alone don't fully suggest. The room comfortably fits a full-size double or queen bed with space to move freely on both sides. It's a good reminder that a two-bedroom ADU doesn't need a large footprint to feel generous — it needs height, natural light, and storage that doesn't eat into the floor.

Interior | Bedroom Two

The second bedroom shares the same design language as the first: white walls, oak flooring, a consistent wardrobe and shelving arrangement, and natural light from a dedicated window. Where the two rooms differ is in their specific window position and framing, which means each feels like its own space rather than a repeated copy.

The wardrobe and integrated shelving combination is the same floor-to-ceiling arrangement: white flat-panel cabinetry with black handles alongside a warm oak open shelving unit. This approach keeps storage capacity high without requiring extra furniture and maintains the clean, uncluttered aesthetic that runs through the whole home. The room's layout also allows for a desk or study nook in the corner beside the shelving unit, a small but practical option for a resident working from home or a student.

Both bedrooms sit in the private rear zone of the home, separated from the open-plan front area by the layout planning of the design. The positioning means the bedrooms are quiet and away from the social activity of the kitchen and living space, a deliberate zoning decision that makes the home more comfortable for longer-term occupation, multigenerational arrangements, or guest accommodation where people value independent, private space.

Linea House in Summary

Linea House is a two-bedroom ADU design concept that holds together well across every part of the brief. It's got a clean exterior that belongs in a residential backyard, an open-plan living zone that's genuinely well-lit, two private bedrooms with proper storage, and a bathroom that feels larger than its footprint suggests. It's the kind of 2 bedroom ADU design that works as a long-term dwelling rather than occasional accommodation.

It suits a range of uses:

• Multigenerational living where family members need independent but connected space

• Backyard rental for homeowners looking to add a secondary income source, where local regulations allow

• Independent living for adult children, elderly relatives, or housemates

• Compact primary home for a couple or small family wanting an efficient, well-resolved layout
