The half duplex is the signature inner-city infill form, and West Hillhurst has one of the deepest markets for it in Calgary. These are new-build semi-detached homes put up in pairs on redeveloped lots — typically three storeys or two with a developed lower level, an attached or detached rear garage, and frequently a legal or suite-ready basement. Buying one is a different exercise from buying a suburban semi: you are choosing a builder, a vintage and a block, not a floor plan from a brochure. several semi-detached homes are for sale.
Redevelopment has been running here long enough that the semi-detached stock spans several build generations, which is genuinely useful — you can compare an early infill against a recent one on the same street and see what changed. The central grid is where they concentrate. Sizes and layouts vary more than the exterior suggests: some pairs are built as mirror images, others are not, and the lower level might be finished as family space, as a separate suite, or left for a future one. The appeal is straightforward — a new home with modern mechanical systems, warranty coverage and no renovation backlog, on a walkable grid with the pool and rink, the 19 Street cafes and Kensington all close, and downtown about seven minutes away.
Infill quality varies by builder, and that is the whole game. Ask who built it and when, what the warranty covers and how much of it is left, and look at party wall construction and sound transfer specifically — it is the thing owners most often wish they had checked. Confirm how the two halves are titled and whether any shared elements, insurance or maintenance obligations sit between them. Where a suite is present or advertised as possible, treat legality as unverified until you have confirmed permits and registration with the City of Calgary. Check the land-use designation on the neighbouring lots too: on an active infill block, the vacant house next door may not stay standing.
Measured over September 2025 to August 2026 from MLS® data, on 37 semi-detached sales. Aggregates only, for a stated window; the listing counts elsewhere on this page are read live.
37 of the 136 West Hillhurst sales in the window were half duplexes. That is the redevelopment rate showing up in the sales record.
The detached median over the same window was $1,211,500, so a half duplex traded about 17% below it.
Detached ran 1,996 sq ft over the same window, so the half duplex is not automatically the smaller home.
Detached in West Hillhurst ran 19 days over the same window, so half duplexes moved in line with the houses beside them.
Measured against the last asking price, so it understates what a seller gave up if the price was reduced on the way.
Two homes sharing one wall. In Calgary a semi-detached home is usually freehold: each half sits on its own titled lot with no condominium corporation, which is the part buyers most often get wrong. Some are bare-land or conventional condominiums instead, with a fee and a board. The title and the listing’s ownership type settle it — two identical-looking halves on the same block can be held either way.
A single inner-city lot that can be redeveloped as two attached homes carries its land cost across two sales instead of one. That arithmetic is what has been rebuilding these streets, and it is why the newest housing in West Hillhurst is more likely to be attached than detached, and why a half duplex here is often the newer, larger and better-finished home on the block rather than the compromise.
Ask what the wall is built of and how far it goes: a wall that runs to the underside of the roof deck, with proper fire separation and no shared framing, is a different home to live in than one that stops at the ceiling. Sound transfer is the most common regret. Where the two halves are held freehold, check whether a party wall agreement is registered on title and what it says about maintenance, insurance and access for repairs.
Confirm the water, sewer and gas services are separate rather than shared through the neighbouring half, and find out who owns the fence, the walkway and the drainage between the two properties. On a new build, ask for the Alberta New Home Warranty documents and confirm what remains of the coverage — it runs from the date the home was first occupied, not from your possession date.
The streets buyers ask about most here are the river-adjacent blocks — the southern streets near Memorial and the Bow pathways, the infill heartland — the central grid where semis and infills have replaced originals in volume, the character-home streets — remaining originals and bungalows priced on land and block, the pool-and-rink core — the blocks around the community association's outdoor pool and rink and the 19th Street pocket — the community's own walkable cafe and restaurant strip.
Nearby amenities include West Hillhurst Community Association outdoor pool and rink, the 19th Street NW cafe and restaurant pocket, Kensington shops and restaurants, a walk east and Helicopter Park. Access is via Memorial Drive — downtown in about seven minutes, Crowchild Trail and Kensington Road NW.
