A Family-Built Ottawa Contractor, Grown into a Commercial Design-Build Leader

Kat Designs & Construction Inc. began in 2010 as an Ottawa renovation company built on a simple family standard do the work properly and stand behind it.

That standard has carried us from home renovations into commercial design-build, and today business owners in Ottawa, the GTA and across Ontario trust us to plan, design and construct the spaces their businesses depend on.

We still run every project the way a family business should, with owners who answer the phone and a team that treats your budget and your opening date as if they were our own.

Our Vision

To be the contractor Ontario business owners call first when they are ready to open, expand or reinvent their space, because we deliver the building and the opening date we promised.

Our Mission

We take business owners from concept to opening day through a single design-build team, with clear pricing, a realistic schedule, permit and code expertise, and commercial-grade workmanship on every project, whether it is a franchise restaurant, a medical clinic or a custom home.

What We Build

Commercial Construction and Design-Build Services in Ottawa

Whether you are opening your first location or your fifth, we plan, design and build spaces that meet your brand standards, pass inspection the first time and open when you need them to.

One team handles design, drawings, permits and construction under a single contract, which means fewer hand-offs, faster  decisions and one point of accountability from concept to keys.

We turn leased and  owned spaces into  working offices and retail stores, managing tenant improvements, landlord requirements and building code so your space is ready to trade.

We build dental, physiotherapy and medical clinics with the plumbing, accessibility, infection-control finishes and treatment-room layouts that healthcare spaces require.

From kitchen ventilation to front-of-house  finishes, we deliver restaurant and franchise build-outs that meet brand standards, health inspections and grand-opening deadlines.

We construct and renovate warehouse and distribution spaces with the slab, loading, racking and power planning that keeps your operation moving.

When a project does not fit a standard category, such as an indoor pickleball facility or a recreation venue, our design-build team engineers the solution from the ground up.

We bring the same commercial-grade discipline to residential projects, including custom homes, coach houses and finished basement and recreation spaces.

Why Katcons

Why Business Owners Choose Katcons as Their General Contractor

Opening a new location is one of the largest investments a business owner makes, and every week of delay means rent paid on a space that is not earning.

 

We built our process around protecting that investment, so you get the clarity of a single contract, the confidence of a fixed plan and a team that is accountable for the result.

One Team, One Contract

Design, permits and construction sit with one accountable team, so you never have to referee between an architect and a builder.

Built Around Your Opening Date

We plan backwards from the day you need to open, sequencing trades, inspections and long-lead equipment to keep the launch on track.

Clear Pricing, Fewer Surprises

Detailed estimates and design decisions made early in the process mean you understand the scope and budget before construction begins.

Family-Built Accountability

As a family-built company since 2010, our owners stay involved in every project, and our reputation depends on you recommending us to the next business owner.
