Cost to Build a Custom Home in Killarney, Calgary

Why Build in Killarney?

Killarney is one of Calgary's most actively redeveloping inner-city southwest neighbourhoods — close enough to 17 Ave SW and Marda Loop for cafés and groceries on foot, close enough to downtown for an under-15-minute commute, and large enough on lot to support meaningful infill. Buyer demand for new construction here skews toward design-driven semi-detached pairs and three-storey single-family builds with rooftop patios. The 1950s bungalow stock is at the tail end of its economic life, so teardown-and-rebuild is the dominant pattern.

Design Considerations for Killarney Lots

Killarney lots are typically narrower at street frontage and slope slightly toward the back. Many corner lots in the area are excellent candidates for two-unit infill with separate street addresses, which improves resale. Watch for hidden underground oil tanks and old gas lines during demolition planning — they are not uncommon on 1950s lots. The area's tree canopy is mature and protected.

Common Build Types Here

Side-by-side semi-detached infill, modern single-family custom builds with legal basement suites. Most projects in Killarney fall into the 2,400 – 3,000 sqft, 2-storey + finished basement range, and Inner-city families wanting walkability without a downtown condo footprint; investors building for the inner-city resale market.

Total Project Cost Breakdown

A realistic 2026 budget for a custom build in Killarney, assuming a 2,400 – 3,000 sqft, 2-storey + finished basement mid-range custom home:

Cost Component	Typical Range
Land (typical 50 ft × 120 ft lot)	$460,000 – $620,000
Demolition & site prep	$20,000 – $50,000
Construction (2,400 – 3,000 sqft, 2-storey + finished basement)	$600,000 – $820,000
Design, engineering & permits	$40,000 – $80,000
Total project (land + construction + soft costs)	$1,120,000 – $1,520,000

Ranges reflect 2026 inner-city Calgary infill costs at $260–$320/sqft for mid-range custom finishes. Higher-end finishes, complex sites, or legal basement suite inclusion push toward the top of each range.
