Custom Homes Built Around How Your Family Lives
A custom home is one of the biggest investments most families make — in money, but also in how you live for the next twenty years. For more than thirty years, Mighton Construction has built homes across South Georgian Bay, from Wasaga Beach waterfront to Blue Mountain estates and Simcoe County acreage.
We deliberately take on only eight to ten projects a year, so Jeff and Adam Mighton are personally involved in every one. With open-book, cost-plus budgeting, you always know where your project stands and what it costs.
What we build
Custom Homes for the Way You Live Here
From shoreline lots to sloped mountain sites and open acreage, we build homes designed around your family and the conditions of your property. Every project is engineered for South Georgian Bay — and for how you actually want to live in it.
- Waterfront homes — on Georgian Bay and inland lakes, engineered for shoreline conditions and conservation authority requirements
- Four-season estates — in Blue Mountain, Craigleith, and the Collingwood corridor, built for year-round living and entertaining
- Rural custom homes — across Springwater, Clearview, and Simcoe County acreage with wells, septic, and long private approaches
- Energy-efficient ICF homes — insulated concrete form construction for superior insulation, quiet, and lasting comfort
- Cottage replacements — a year-round home built on the same cherished footprint
Built for South Georgian Bay
Engineered for the Conditions Here
Building on the bay is not the same as building in southern Ontario. We engineer for the climate, ground, and approvals that define this region — so your project moves forward without surprises.
- Engineered for our climate — snow loads that exceed southern Ontario requirements, and envelopes detailed to manage moisture off the bay
- Foundations for our ground — systems specified for local frost depth and the varied soil conditions across the region
- Local approvals navigated — we know the Nottawasaga Valley and Grey Sauble Conservation Authority processes and manage them for you
The ICF advantage
ICF Custom Homes Engineered for Georgian Bay
As certified Nudura and Foxblocks installers, we build with insulated concrete forms — a method exceptionally suited to our climate. Compared with standard wood framing, an ICF home is quieter, stronger, and dramatically more efficient to run, year after year.
- A far tighter, better-insulated envelope than a typical framed wall
- Lower heating and cooling costs through hard winters and humid summers
- Monolithic concrete that stands up to high winds and dampens outside noise
- Materials that won’t rot, warp, or feed mould — durability measured in decades
Why Mighton
A Custom Home Builder Who’s Actually There
We take on only a handful of homes each year so that Jeff and Adam Mighton are personally involved in every one — on site, reachable, and accountable. With open-book, cost-plus transparency, you always know exactly where your project stands and what it costs. No layers, no surprises, no hand-offs.

Our Custom Home Building Process
Discovery & Vision Alignment
We meet at your property to understand how you want to live, assess the site and its conditions, and align on a realistic budget and timeline before anything is drawn.
Concept & Budget Alignment
Working with your architect or one of our trusted design partners, we shape a concept that fits your vision and your budget — so there are no costly surprises later.
Design Refinement & Specifications
We refine every detail, select finishes and systems, and lock specifications so your home is fully defined and priced before construction begins.
Permits & Pre-Construction Planning
We secure permits and conservation approvals, finalize the cost-plus budget with open-book transparency, and build the construction schedule.
Construction & Project Management
Our in-house crew manages every phase — foundation to finishes — with Jeff and Adam personally on site and regular progress updates throughout.
Final Handover & Ongoing Support
We complete a thorough walkthrough, address every detail on the punch list, and stay available long after move-in to stand behind the quality of our work.

Client reviews
What Our Clients Say
We just finished building our new custom home with Mighton Construction, and honestly, the whole process was fantastic. The final craftsmanship is beautiful — you can tell they only work with the best, most reliable local tradespeople. If you’re looking to build new in Tiny Township, Wasaga Beach, or surrounding areas, you won’t regret hiring Mighton.
They just finished our ICF basement in Wasaga Beach, and the results are incredibly solid and perfectly executed. Jeff and Adam were exceptional, overseeing every detail with expertise. It’s a huge piece of our new home, and knowing it’s built with such care gives us so much peace of mind.
From our first conversations with Jeff and Adam, we knew they understood our vision for a multi-generational cottage. The skilled team demonstrated remarkable craftsmanship in every detail of our 3,500 sq ft home, and the quality is evident throughout. They built more than a cottage — they built the foundation for countless family memories.
