About Replacement Design

Residential Design Support Built Around Toronto Homes

Every home has its own structure, its own lot, and its own set of limits. We start by looking at what’s already there. Before any design work begins, we review the property, the zoning, and how you use the space now, so we can tell you what’s realistic on your lot.

Our work covers house and home additions, home renovations and interior alterations, garden and laneway suites, multi-unit conversions, new builds, zoning bylaw review, and permits and Committee of Adjustment applications.

It’s a common place to start. We help establish the design and permit requirements first, giving your contractor a clearer project to price.  

Zoning Bylaw Review

We check what your property allows before design begins.

Committee of Adjustment

We prepare the application and represent you at the hearing when a minor variance is required.

Our Services

Residential Design Services in Toronto

Every project starts with two questions: what does the property allow, and what will the City approve? We work across the full range of residential design — additions and renovations, garden and laneway suites, multi-unit conversions, new builds, and the permit work that comes with them. Start wherever your project sits, and we’ll help you understand the next step.

House & Home Additions

Need more space without leaving the neighbourhood you chose? We design rear, second-storey, and side additions, as well as garage conversions, for Toronto homes.

Home Renovations

A layout change can transform how a house works. We design kitchen, bathroom, basement, and whole-home renovations, as well as interior and exterior alterations.

Garden Suites

A garden suite adds independent living space in your backyard, whether that's for family, rental income, or aging in place. We check what your lot allows first.

Laneway Suites

Laneway suites are possible on eligible Toronto properties. We confirm eligibility, design to the requirements, and prepare the drawings the City needs.

New Builds & Custom Homes

Building from the ground up? We design custom homes around your lot, your budget, and how you want to live, with the approval path planned from the start.

Multi-Unit Conversions

Duplex, triplex, or a legal basement apartment. We handle the zoning analysis and design work needed to add housing within an existing Toronto property.

Permits & Approvals

Building permit applications, minor variances, and Committee of Adjustment hearings. We prepare the documentation and represent you through the process.

WHY CHOOSE US

Why Work With Replacement Design Inc.?

Planning a renovation, addition, or new home can be difficult when you’re not sure what your property allows or where to begin. We help make the process clear by looking at the property, the zoning, and the requirements before the design moves forward.

Design With the Approval Process in Mind

We consider your property’s zoning and requirements from the beginning, helping you develop a design that is practical for your home and suitable for the approval process.

Clear Project Direction

Before design gets underway, we look at what you’re working with and help you understand what’s possible, what may require additional approvals, and what the next steps look like.

Support Through Approvals

From permit drawings to Committee of Adjustment applications, we prepare the required documentation and help guide your project through the approval process.

Our approach is practical and collaborative. We listen to how you want to use your home, work within the property’s limitations, and keep the approval process in mind throughout the design.
