Second-storey, main-floor and lower-level additions that look original to the house.
Home Additions with Kay2
Kay2 Contracting, NW Calgary
Kay2 designs and builds renovations and additions across northwest Calgary, including a second storey on a St. Andrews Heights bungalow and an award-finalist family home addition.
Northwest Calgary is full of established neighbourhoods where families love the street but have outgrown the house. Kay2 plans, designs and builds renovations and additions there with in-house design at no extra charge, a fixed-price contract signed before construction starts, and one project manager from planning to handover.
In St. Andrews Heights, a family of four had outgrown a two-bedroom bungalow. Kay2 added a second storey of more than 800 square feet with a primary suite and three bedrooms, rebuilt the main floor around a new kitchen, and gave the house a new stone and stucco exterior. Elsewhere in the northwest, our 19th Street home addition added a chef's island kitchen, a mudroom and a primary retreat, and its ensuite was a 2023 BILD Calgary Region Awards finalist.
Homes in NW Calgary are inside city limits, so building permits are issued by the City of Calgary. Kay2 plans permits, lead times and each phase of the work before construction begins.

Our process
Plan, design, build: five steps from the first conversation to the final walkthrough.
A complimentary conversation about your home, how you want to live in it and what must be included.
An estimator shapes your wish list into a scope and budget, with options you may not have considered, and discusses financing.
Architectural drawings, then finishes and fixtures chosen at the Showroom. Permits, lead times and each phase are scheduled before work begins.
Structure, systems and finishes built to the drawings, on a protected and tidy site, with a weekly status email.
A detailed walkthrough checklist, final inspections and sign-off only when you are fully satisfied.
