Winston Heights/Mountview, Calgary: infills that run 2,695 sq ft

New houses in Winston Heights/Mountview are big. City of Calgary open data on permits issued from January 2023 to 29 September 2026 shows 31 new single-detached houses with a median floor area of 2,695 sq ft, the third largest median of the 18 Centre communities profiled here, and 21 of them at 2,500 sq ft or more. Rowhouses are the newer story: 20 rowhouse and townhouse permits were issued here in 2026 to date, after 4 in each of the two years before.

How big are new houses in Winston Heights/Mountview?

Most land between 2,500 and 3,000 sq ft. Of 31 new single-detached permits with a floor area, 14 were in that band, 7 were 3,000 sq ft or more, 7 were between 2,000 and 2,499 sq ft and 3 were under 2,000. None were under 1,500 sq ft.

The floor area the applicant entered on the building permit, for new single-detached houses issued in the same window. It usually excludes the basement. Source: City of Calgary open data (building permits, development permits, secondary suite registry, census 2021 population, census 2021 households, civic census 2019, land use districts), retrieved 5 October 2026.

The median moved from 2,862 sq ft in 2023 to 2,367 sq ft in 2024 and 2,389 sq ft in 2025, then 2,935 sq ft in 2026 to date. With 6 to 9 houses a year, a single large project can move the median a lot.

The median declared value of $465,762 is what the applicant wrote on the permit and runs below what these houses cost to build. The custom home cost guide puts 2026 numbers on a house this size, and the new home permit time guide explains the wait. Here the median house permit took 37 days to issue.

Small households in a mix of house types. The 2021 census counted 3,605 people in 1,650 households, an average of 2.2, with 34% of households one person and 14% of residents 65 or older.

Newer communities have grown since.

The 2019 civic census found 831 single-detached dwellings, 383 duplex units, 249 converted structures and 202 townhouses among 1,803 dwellings. Duplexes were 21% of homes, eleventh highest of the 87 communities profiled here, and converted structures 14%, ninth highest. Just under half, 49%, were owner-occupied.

What about suites?

They come mostly as new construction. Twelve suite permits were in the City's New work class, a suite built as new construction in a new or an existing house, against 10 for altering existing space into a suite, and 6 backyard suites were issued from 2023 to 2025. The new-construction suites had a median declared value of $77,811, tenth highest of 72 communities.

Development permits applied for from 1 January 2023; many home projects in Calgary need only a building permit, so these are a subset of all work. The registry lists suites the City has confirmed meet the rules, not every suite that exists. Source: City of Calgary open data (building permits, development permits, secondary suite registry, census 2021 population, census 2021 households, civic census 2019, land use districts), retrieved 5 October 2026.

Nineteen of the community's 175 development permit applications were for suites. The registry holds 143 suites, with 24 added in 2024 and 22 in 2025. As of October 2026, a secondary suite is a permitted use in R-C2 and R-CG, and a lot can hold one suite, not both; the legal basement suite guide has the full rules.

What land use covers Winston Heights/Mountview?

More than half is S-R. That recreation district covers 51.9% of the community's districted area, and special purpose districts 60.3% in all. R-C2 covers 28.5%, M-C1 4% and MU-1 2.9%.

The share of the community's districted area in each land use district, from the City's district and community boundary maps intersected exactly. Districts change by lot and by amendment: check a specific lot on the City's land use map before you plan.

Development permit applications named R-CG 78 times and R-C2 54 times. Check your lot on the City's land use map, since R-C2, R-CG and M-C1 each carry different rules.

Walking a 2,700 sq ft infill at full size

A large infill plan often puts the main floor in a long run of rooms, one after another, and the question is whether the middle of the house gets light or turns into a corridor. On the studio's walkable LED floor, the plan is lit at full size, one floor at a time, with room names and dimension lines. You can walk front door to back door and see the sightlines, with a dining table, chairs and sofas moved into place.

Elevations show on a wall-size screen behind the floor. Changes appear on the floor as you make them, and you keep the recording. Send the plans as a PDF or DWG at least three days ahead. Quotes are free and depend on the plan's size: see pricing, book a session, or return to the communities hub.
