Z Square Design & Build Difference

Four Pitfalls 1st Time Home Owner Need to Avoid


1. No More Over Budget

With a fully inhouse team of architects, interior designers, engineers, builders, and material suppliers, we quote on cost, not estimate. Clarify construction cost from day one.

Our clients can achieve their goals with our financially intuitive quotes right from project launch. An endless climb in cost during construction is often explained by unrealistically low builder pricing that with missing elements and non matching-quality material for attractive pricing. Estimates require upgrades and quality checks during construction can drive up project cost by up to 10%~30% higher than your initial fixed contract, and extend move-in schedule significantly. With full inhouse team, We prioritize a detailed costing and schedule that ensures your first quote is almost always your final quote. Our greatest pride is our ability to minimize contingency on every building project.

2. No More Coordination Add-up

Efficiency - We do everything in-house.

Due to a highly disconnected professional market, architects, engineers, builders, and material suppliers work alone and this disrupts communication and problem-solving. To overcome these and inherent cost implications, we have created a product-driven work environment with inhouse architects, engineers, interior designers, builders, and material suppliers. We guarantee top-of-class design & build service at competitive pricing. A dedicated architect project manager leads your weekly in-person and cloud-based coordination during construction to keep everything to budget and schedule.


3. No More Unknown Construction Schedule

Real-Time: Our Cloud-based App updates owner 24/7

In home construction, sub-trades often have overlapped job schedules and a small incidence could considerably delay your home. Waiting on one trade could create a chain delay effect. Hence, we manage all the trades through a cloud-based scheduling tool that updates schedules in real-time to enhance booking efficiency, material delivery and trade coordination.  The project schedule also comes as an accessible online calendar on our client portal.

Contractor to coordinate city inspector for final inspection, contractor to explain future warranty policy 

Due-diligence to confirm building area based on land

Garden Suites (Toronto)

On January 12, 2022, the Toronto Zoning By-law Amendment permits the development of Garden Suites in residential Neighbourhoods.  We offer design, permit & construction on stop solution for Garden Suites for our clients in Toronto.

The Garden + Suites project is one of several studies that the City of Toronto is leading through its Expanding Housing Options in Neighbourhoods initiative. A Garden Suite is a detached housing unit, usually located in the rear yard, and is separate, or detached from the main house. Garden Suites, like Laneway Suites, are generally smaller than the main house on the lot and are intended to function as a rental housing unit.


Z Square Group is a leading design-build firm in Toronto, we are already working on Garden Suite projects in Toronto. We think it is an excellent opportunity for Torontonians to expand their living space, create a fully functional home for the next generation, and an investment home for rental. 

Contact us to see if your existing home is eligible to build a Garden Suite, and cost estimate.
