What's better than selling one duplex? Two duplexes, naturally, and I'll show you how with this design.
More residential units built on a single lot is one way of gaining a higher return on investment, but the single-building fourplex is still mostly a foreign concept to banks, other lenders, to builders, to designers and architects, to buyers, and to realtors. The unfamiliarity carries a higher risk and seems to have resulted in a lower appetite, and the four-unit promise of Bill 44 all be evaporated.
Vancouver is one of the handful of cities in which the SSMUH / multiplexes which allows more than one principal building - what it refers to as a "courtyard" arrangement. These buildings can also be duplexes, opening the way to selling half-duplexes.
DCA15 is a pair of twins for a typical 33' x 122' Vancouver single R1-1 property; the rear duplex is a mirror image of the front building, to reduce the amount of problem solving the builder must do on site.
A simple rectangular building form and uninterrupted gable roof keep the primary structure economical. Instead of jogging the structural walls and foundation to create visual interest, the front elevation is divided into a light-coloured residential volume and a darker, wood-screened outdoor zone. This reduces the apparent width and bulk without complicating the building footprint. The single sloped roof is also well suited to a wet coastal climate because it provides positive drainage, avoids internal roof drains, and limits the number of roof intersections and flashing conditions. A restrained palette of stucco, stained wood, and metal trim reinforces the composition while allowing the envelope to remain straightforward, durable, and comparatively economical.
From street level, the main gable gives the duplex the familiar silhouette of a house despite accommodating two dwellings. The off-centre composition prevents the façade from reading as an oversized version of a conventional detached house, with the balcony and timber screen concentrating depth and detail on one side. The windows are positioned according to the needs of the rooms behind them rather than arranged as a decorative grid, while the quieter side of the façade limits overlooking between closely spaced homes.
Most of the building’s architectural character is produced through cladding, roof-edge detailing, and the balcony enclosure rather than costly changes to the structure or footprint. The balcony is vertically supported rather than heavily cantilevered, which simplifies framing, reduces thermal-bridge concerns, and makes waterproofing less dependent on elaborate detailing. Its side fins also provide some privacy from the neighbouring property. The stained wood is concentrated where it provides the greatest value: at the roof perimeter, around the principal outdoor space, and along the entrance route. Along the side elevation, the wood cladding is more welcoming and human in scale without adding unnecessary construction complexity.
The entry doors are grouped beneath one continuous projecting cap, creating a coherent entrance zone while providing basic weather protection. This avoids the cost and flashing complexity of constructing a separate canopy over each door. Locating two entrances along the side also preserves valuable frontage and allows the street elevation to retain the uncluttered appearance of a home rather than a row of competing unit entrances.
The U-shaped kitchen is compact yet efficient. It provides more storage and preparation space than is too common in similarly sized condominium suites. The result is a practical kitchen that supports routine household use without requiring a larger floor area or an oversized island.
A compact multiplex is one situation in which open planning can work particularly well without producing a cavernous or poorly defined interior. The dining area accommodates a full-sized table rather than relying on a token counter with a few stools, which makes the space more useful for families, guests, and long-term living. The large dining-room window brings daylight toward the centre of the plan, while the balcony door extends the living area outward. The quality of the space comes primarily from proportion, daylight, and the relationship between rooms rather than costly ceiling changes or decorative construction.
The living room has traditional, usable proportions rather than the compressed dimensions found in many contemporary condominium plans. A large glazed door connects the room directly to the balcony, while carefully controlled window sizes provide generous daylight without sacrificing privacy or usable wall area. The room is broad enough to support more than one furniture arrangement, which distinguishes a genuinely livable space from one designed around a single marketing layout. The vertical stained-wood slats used outside are repeated indoors as a feature wall, while also maintaining a visual connection to the entry and stair beyond.
The bedroom accommodates a full-sized bed with circulation on both sides, demonstrating that the project has not achieved density by reducing private rooms to their legal minima. The raised window sill provides privacy and leaves useful wall area for furniture, while the straightforward rectangular plan avoids the awkward corners and residual spaces that often result from overly articulated exterior massing. The room remains architecturally restrained, allowing residents to furnish and personalize it without having to work around an overly specific interior concept.
The shared outdoor area between the two duplexes turns the required building separation into useful common space rather than surrendering it to asphalt, utilities, or a neglected side yard. A central path provides clear circulation between the entrances, the street, and the rear of the property, while planting softens the relationship between the buildings and creates privacy at the ground-floor windows. The lawn is modest but functional, with enough space for informal interaction without pretending that four suburban backyards can be fitted onto one lot.
