Designer Prefab Homes.





  • Peace of mind with 3 industry leading principles.

  • 1. Price Certainty

    2. Timeframe Certainy

    Ready in 6 months or less from start of manufacturing, enjoy an accelerated build timeframe as your home is precision engineered in our state of the art factory. We’re never delayed by rain, snow or theft, so your new designer home is move-in ready before you know it.

    3. Quality Certainty

    Craftsmanship, premium materials and modern process come together in each Karoleena home. The quality of our homes is assured and the common concerns associated with a traditional custom home builder are alleviated.

  • "You’ve just witnessed the assembly of a Karoleena Custom Homes system-built residence; five months to build in a factory but only eight hours to assemble by crane on the site. By contrast, a conventional build can take 18 to 24 months before it’s completed" - Alberta Venture
