House & Home Additions Toronto | Replacement Design Inc.
Types of Home Additions We Design
Rear Additions
Expand your main floor with a rear addition designed for larger kitchens, open living areas, family rooms, and better indoor-outdoor connection.
Second-Storey Additions
Add upper-level living space for bedrooms, bathrooms, offices, or growing family needs while improving the function of your existing home.
Side Additions
Use available side-yard space to create extra rooms, wider layouts, improved entrances, or better flow through the home.
Sunroom & Porch Additions
Create brighter, more comfortable transition spaces that bring natural light, outdoor views, and everyday flexibility into your home.
Garage Conversions
Transform an existing garage into useful living space, such as an office, studio, guest room, gym, or family area.
Our Design & Permit Process
Every addition begins with understanding your home, goals, property, and approval needs. Our process moves from consultation and design direction to drawings, permits, and project guidance, keeping each step clear and practical.
Consultation & Property Review
We begin by learning about your goals, your home, your lot, and the type of addition you’re considering.
Design Direction
We explore layout options, addition styles, space planning, and practical ways to connect new areas with the existing home.
Drawings & Documentation
We prepare clear design drawings that can support pricing, permit planning, and the next steps in your project.
Permit & Approval Support
When permits or approvals are required, we help prepare the documentation needed to move the project forward.
Project Guidance
As questions come up, we provide design support to help keep the project aligned with the approved direction.

Frequently Asked Questions
01 What is the best type of home addition for my property?
The best type of addition depends on your lot, existing home layout, zoning limits, budget, and goals. Some homeowners need a rear addition for more main-floor living space, while others need a second-storey addition for bedrooms or a side addition for better layout flow.
02 Do I need a permit for a house addition in Toronto?
Most house addition projects require a building permit. Depending on the property and proposed design, the project may also require zoning review or Committee of Adjustment support.
03 Can you help with drawings for permits?
Yes. Replacement Design Inc. prepares permit-ready drawings for home additions, renovations, and other residential design projects.
04 How early should I contact a designer for a home addition?
It’s best to contact a designer before speaking with contractors or finalizing your budget. A clear design plan helps you understand the scope, layout, approval needs, and project direction before pricing or construction begins.
05 Can a home addition increase property value?
A well-planned addition can improve function, comfort, and long-term property value. The most successful additions are designed around the home’s layout, the neighbourhood, and the homeowner’s real needs.
