About us
More Space Without Leaving Home
A home addition changes a property's footprint, so the project needs to work with the existing house and the lot.
The right approach depends on what you want to gain. A rear extension may create a larger kitchen and dining area. A side addition may provide another bedroom or office. Building upward can add rooms without taking as much garden space.
Related work may include home extension, kitchen renovation, flooring, electrical services, plumbing, roofing services, landscaping.

Learn More →Why Choose Our Team?
01
We Consider the Whole House
An addition should not feel like a separate box attached to the property. Its structure, access, services, and appearance need to work with what is already there.
02
Choose the Right Direction
Building outward, adding another floor, or changing an existing area each has different effects on the property.
03
Keep Daily Life in Mind
The new room should solve the reason you need more space, whether that means another bedroom, a larger kitchen, or a dedicated work area.
04
Respect the Lot
Setbacks, lot coverage, access, grading, and other planning factors can affect what you can build.
05
Coordinate the Building Work
An addition can involve excavation, framing, roofing, windows, insulation, electrical, plumbing, heating, and interior finishing.
06
GTA Home Service
We help homeowners plan and build additional space around the needs of their existing property.
How We Work
From an Idea to an Added Part of Your Home
01
Define the Extra Space
We identify what your household is missing and what you want the new area to accomplish.
02
Study the Property
We consider the existing house, lot, access, structure, and potential addition area before planning the work.
03
Prepare the Build
We organize drawings, approvals, materials, trades, and construction stages according to the project.
04
Build the Addition
The new section is constructed and connected to the existing home before the interior and exterior details are completed.
The Difference
What Extra Space Can Change
Sometimes the problem is not the size of the house itself. It is the lack of one particular room. Adding the right space can change how the rest of the home is used.
01
Give Children Their Own Room
Add sleeping or study space when the household has outgrown its current arrangement.
02
Separate Work From Home Life
Create a dedicated office instead of using the dining table or a bedroom for work.
03
Open Up Family Time
Create a larger space where people can sit, eat, play, or relax together.
04
Improve Kitchen Flow
Give food preparation, dining, and storage more breathing room.
05
Welcome Guests Properly
Add a bedroom or living area that gives visitors a more comfortable place to stay.
06
Stay in the Neighbourhood
Gain useful floor area without giving up a home and location your family already enjoys.
