When people think about a garage suite, most of the attention naturally goes upstairs, where the homeowners live. But in our experience, the ground floor/garage level is one of the most important parts of the entire build.

It’s where vehicles are stored, where long-term flexibility lives, and where small planning decisions can make a big difference in comfort, durability, and future use.

Here’s how we approach the ground floor when designing and building a garage suite in Edmonton, with examples from the Hazeldean garage suite project.

Flexible Garage Layouts for Owners and Tenants

One very important decision is how the parking area itself is laid out.

Some homeowners prefer one large shared garage space. Others choose to divide the garage into two distinct parking areas, one for the homeowner and one for their tenant. Both options work well; the right choice depends on lifestyle, privacy preferences, and who the suite will be used for.

This is something we walk through early in the design phase so the garage layout supports the homeowners’ daily life.

At the Hazeldean garage suite, we designed the ground-level garage as a single, open space that comfortably accommodates two vehicles, reflecting the homeowners’ plan for multigenerational living.

Flexible Ground-Floor Room: Storage, Office, or Rental Space

Many of our Edmonton garage suite floor plans include an additional room on the ground floor, and how it’s used is entirely up to the homeowner.

Some choose to designate it as part of the rental suite, while others prefer a lockable room they can access themselves. We’ve seen this space used as:

• A home gym/yoga room (this was the Hazeldean garage suite owners’ choice)
• A workshop
• Seasonal gear storage
• A home office (as seen in the Windsor Park garage suite)

By designing the space with flexibility in mind, including the door placement and optional locks, the garage level can adapt as needs change over time.

Garage Doors, Windows, and Security for Your Garden Suite

Garage doors aren’t one-size-fits-all. Homeowners can choose whether or not they want windows in the main garage door, balancing natural light with privacy and security.

If the garage suite is built in a back-alley, we generally recommend limiting window openings in the garage. If windows are added, we prefer small, high-placed windows that bring in daylight without creating security concerns or clear sightlines into the space.

This approach keeps the garage bright enough to work in but keeps it secure.

Preventing Cold Garage Suite Floors Through Proper Insulation

The garage plays a major role in the comfort of the suite above it.

We insulate the garage carefully so cold air doesn’t transfer upward and create chilly floors or temperature swings in the living space. This includes upgrading to R-18 insulated garage doors (2″ thick) instead of standard R-12 doors (1 ⅜’’ thick), which helps stabilize temperatures and reduce heat loss.

It’s a small detail that has a noticeable impact on day-to-day comfort upstairs.

Also, all of the walls we build use our Thermal-Lock system: a panelized wall insulation method that wraps the structure in a continuous layer of protection from the foundation to the roofline.

Preparing Your Garage Suite for Electric Vehicles

One of the most common future-focused upgrades we recommend is EV-ready electrical in the garage.

Even if a homeowner doesn’t currently drive an electric vehicle, we often install electrical rough-ins and outlets capable of supporting EV charging during the initial build. Doing this early allows us to size the electrical service properly at the permit stage and ensure the lot can handle the load.

Adding EV-ready capacity later can be significantly more expensive, especially if it requires upgrades to the electrical panel or service. Planning for it upfront is a relatively small investment that keeps future options open, whether for the homeowner or a future renter.

At the Hazeldean garage suite, we installed two 240V-ready outlets, so the garage is already prepared for future electric vehicle charging.

Garage Heater-Ready: Small Cost Now, Big Savings Later

If there’s any chance a garage heater might be added in the future, we strongly recommend installing the gas line during the initial build.

Running a gas line while plumbing is already underway is a minor additional cost. Retrofitting one later often requires opening walls or concrete, making it far more expensive and disruptive.

This approach mirrors how we plan for EV-ready electrical. Our goal is to make thoughtful, low-impact decisions early that prevent bigger headaches later.

Why We Coordinate All Concrete Work Into One Pour

Whenever possible, we pour all concrete at the same time, including sidewalks, the driveway, and access paths.

This saves on mobilization costs and ensures that when Edmonton’s spring weather hits, both the homeowner and future tenants have a clean, stable walkway to the suite entrance, instead of mud, slush, or temporary paths. It’s a practical choice that improves the experience during construction and after move-in.

Hazeldean Garage Suite, Pre-Pour

In addition to coordinating timing, we also insulate our flatwork wherever possible. For the Hazeldean garage suite, we installed rigid Styrofoam beneath the garage pad, using extra pieces of our Thermal-Lock that weren’t used in the initial build where needed to ensure consistent coverage across the entire slab. This allows us to use less concrete while helping it harden more quickly, so the trades workers can continue working without delays.

Just as importantly, insulation under unheated concrete spaces like garages, driveways, and sidewalks helps protect against freeze-thaw movement. In Edmonton’s erratic climate, temperature swings cause the ground beneath concrete to expand and contract, which can eventually lead to cracking and shifting. By insulating below the slab, we reduce that movement and improve the long-term durability of the suite.
