Building a Custom Bungalow in Ontario: Trends and How to Plan

A custom bungalow build lets you design one-level living around your exact needs, from accessible layouts to energy-efficient systems and income suites. In 2026, popular trends include open main floors, bungaloft designs, heat pumps, walkout basements and legal secondary units. This guide covers what owners are choosing and how to plan a build in Ontario.

Why build a custom bungalow?

Few new detached bungalows are built by large developers in the GTA because land is costly. If you want a modern bungalow, building your own is often the way to get one.

Many owners buy an older bungalow on a good lot, then tear down and rebuild. Others build on rural or cottage lots. Our post on tearing down and rebuilding a bungalow explains when that makes sense.

Top custom bungalow trends in 2026

1. Accessible, age-friendly layouts

More owners plan to stay for decades. Common features include no-step entries, 36-inch doorways, curbless showers, lever handles and main-floor laundry. These details cost far less to build in than to add later.

2. Bungalofts

A loft above the main floor adds a guest suite or office while keeping the primary bedroom on the ground level. It’s a popular way to add space without giving up one-level living.

3. Walkout and lookout basements

On sloped lots, a walkout basement brings light and direct yard access to the lower level. Bigger windows make basements feel like true living space.

4. Built-in income or family suites

Ontario allows up to three units on most serviced urban lots. Many custom builds plan a legal basement unit or a garden suite from the start, with separate entrances, fire separation and their own utilities.

5. Energy-efficient systems

Heat pumps, high-performance windows, better insulation and airtight construction are common requests. Some owners also prepare for solar panels or EV chargers.

6. Open kitchens and flexible rooms

Large kitchen islands, walk-in pantries and rooms that switch between office, guest room and gym are high on wish lists.

How to plan a custom bungalow build

1. Check the lot and zoning: Confirm setbacks, height limits and lot coverage with your municipality.
2. Hire a designer or architect: Choose one with bungalow and local permit experience.
3. Get a survey and soil report: These shape your foundation and grading plans.
4. Apply for permits: You may need a demolition permit, building permit and possibly a minor variance.
5. Choose a builder: Get at least three detailed quotes and check references.
6. Build in a contingency: Set aside extra funds for surprises, especially with teardowns.

Budgeting and financing your build

Construction costs vary widely by size, finishes and location. Get detailed quotes rather than relying on rough per-square-foot figures. Include design fees, permits, development charges where they apply, utility connections and landscaping.

Construction mortgages work differently from regular mortgages, with funds released in stages as work is completed. A mortgage agent can explain the options. An accountant can tell you whether any new-home tax relief applies to your situation.

Questions to ask a custom builder

• How many custom bungalows have you built in this area?
• Can I visit a finished home and speak with past clients?
• What is included in your price, and what counts as an extra?
• How do you handle change orders and delays?
• Who manages permits and inspections?

Clear answers up front make for a smoother build and fewer disputes later.

Protecting your investment

Ask your builder about warranty coverage on new homes in Ontario, and get every agreement in writing. Have a real estate lawyer review contracts before you sign. Keep all permits and inspection records for future resale.

Frequently asked questions

How long does it take to build a custom bungalow?

Timelines vary with design, permits and the builder’s schedule. Approvals alone can take months, so start planning early.

Is it cheaper to build or buy a bungalow?

It depends on land costs, finishes and the local market. Building gives you exactly what you want, but buying is usually faster and more predictable.

Can I build a bungalow with a basement apartment?

In many Ontario cities, yes, if zoning allows and the unit meets the Building Code and Fire Code. Plan it from the start to save money.

The bottom line

A custom bungalow lets you combine one-level living with modern comfort, efficiency and flexibility. Start with your lot, then plan around the trends that fit your life.
