The 1971 Langner Spherical House
Long before it was Calgary's most talked-about stay, this was the Langner Spherical House: a 1971 prototype geodesic dome, one of only two prefabricated domes in the city, built as a pre-cut kit home from a colour-coded frame. Calgarians have called it the soccer ball house for fifty years.
In 2025 it was added to the City's Inventory of Evaluated Historic Resources. Then three founders bought the weathered blue dome and rebuilt it, panel by panel, into the Dome House you can stay in today.
1971: A Calgary Original
Engineer Horst E.P. Langner designed the prototype for Spherical Housing Systems Ltd. Revelstoke Building Materials Ltd. built it as the FIRST prototype: 104 square metres, $26,000 in 1971 including a car port with covered sundeck, roughly 30% cheaper than other houses of the day. A pre-cut kit home with a colour-coded frame a homeowner could assemble.
The shell is a polygonal wooden-truss dome with interlocking Y-pattern ribs, a Neo-Expressionist design from the 1970s energy-crisis era. It is the first and one of only two known prefabricated geodesic dome homes in Calgary. It spent its first years as the prototype and show home, and the first private owner was Dianne Gill, a nurse, from 1976 to 1990.
The Renovation: 20 Companies Said No
In October 2022 the Dome changed hands. Three founders - Rylia Fielding, Eva Xu and Nathalie Kante - bought the weathered blue dome and set out to rebuild it. The permits were issued in 2022; by spring 2023 the work was underway, and by June 2024 the finished black dome stood on the hill.
The black cladding was a feat in itself. Metal roofing contractor Construct Vision tells it as "20 roofing companies said no. We said yes" - every triangular face had to be individually framed, sealed, and clad by hand. New windows, copper trim, and the river-rock yard and pergola followed, with interiors designed by Rylia.
All of the exterior walls, from the interior side, and the garage were spray foamed — the dome had been framed 2x4 instead of 2x6, and there was no other way to reach the R-value the building code required. The spray foam company oversprayed the interior, and the owners spent a week with a specialty tool sanding the inside of the exterior walls to restore the dome's geometric shape. At one point a crew worked 24/7 for an entire week. When they stripped the exterior, they found it had been coated in truck bed liner — that was why the house was not breathing. They replaced the entire exterior, along with plywood and some framing, and brought everything up to current building code, passing all inspections. And the whole scope — permits, plans, the build, landscaping, and interior decorating — was completed in one year.

The Dome Today
The Dome House you can stay in today sleeps 8 in 3 bedrooms and 2 bathrooms - a whole-home stay for family and friends, celebrations and staycations in a quiet residential neighbourhood. It is 15 minutes from YYC airport, 20 minutes from downtown, and about 1.5 hours from Banff.
