Dungannon Passive House Project

Created on

Welcome to the Dungannon Passive House Project, where sustainability meets innovation! We're thrilled to announce the construction of a Passive House in the village of Dungannon. In partnership with Sommer Brothers Ltd., it's a revolutionary project that's set to redefine sustainable living in our area. Join us on this journey as we delve into what makes this house unique and how it's shaping the future of our community.


When: Sunday May 26 11 am - 1 pm

Where: 89 Isobel St, Dungannon, ON

Who: Everyone welcome, curious neighbours, builders, designers, architects, realtors and of course perspective buyers.

What: Mid-construction open house, a rare opportunity to see and learn about the process of building a high performance home LIVE.

Why: The hidden details are arguably the most important when it comes to durability, comfort, indoor air quality, health and energy efficiency. Most model home tours focus on the shiny beautiful finish and features and while these are very important details. 

Please DM Sommers Brothers Construction your RSVP for the Open House


What is a Passive House?

A Passive House is not just a home; it's a concept designed to minimize energy consumption while maximizing comfort. These homes are built to rigorous standards, focusing on energy efficiency, insulation, and ventilation. By utilizing passive solar gain, superior insulation, and airtight construction, Passive Houses maintain a comfortable indoor climate year-round with minimal reliance on traditional heating and cooling systems.

Why Build a Passive House in Our Community?

The Township values sustainability and environmental responsibility. By constructing a Passive House here, we're not only reducing our carbon footprint but also demonstrating our commitment to a greener future. This project aligns with our community's vision for sustainable development and sets an example for others to follow.

Join Us on the Journey

We invite you to follow along as the Passive House is constructed and witness the transformation of sustainable living in our community. Stay tuned for updates on construction progress, and opportunities to learn more about passive design principles. Follow Sommers Brother's Construction on Facebook and Instagram for up to date progress on the build. 

Together, we're building a brighter, more sustainable future—one Passive House at a time. Welcome to the forefront of green living in our small community!

History of the Dungannon Lot Development

This project began in 2019. A report was presented to Council acknowledging that the Township has struggled with absentee landowners, land-banking, and owners holding onto land with limited improvements or maintenance. Select parcels of land in Dungannon have been vacant and underutilized for far too long.  The private residential market has incrementally constructed on vacant lots; however, many lots still existed. 

To promote development in the existing urban areas of the Township, it was becoming apparent that the past method of waiting for the market to choose to develop on these lands has only been marginally successful. This report was initiated by a 2019 meeting of Sustainable Huron, where a development tool was highlighted as a means of initiating controlled land disposition with the intention of initiating development to address the significant need for attainable (not “affordable” – which is considered subsidized) housing in Huron County. 

In 2019, the Township owned 13 lots in the village of Dungannon, 6 of which were ready for sale with minimal investment necessary (the water connections existed). The idea was presented where the Township would issue a Expression of Interest to developers who could develop property in a way Council determines. A purchase and sale agreement would be entered into that would be conditional on the accepted proposal.  Should the development not occur within a certain time frame, Council could purchase back that land at the same price it was sold, regardless of how much development had taken place. 

The Report to Council highlighted that Municipal property should be sold with the intention of immediate development. Strategically controlling land dispositions ensure that development happens in a timely manner and could encourage the ‘right kind’ of development for the area in question. By taking on this approach, the goal would be to inspire the public and development community to see the opportunities in such places as Dungannon. The Township issued an expression of interest, and Sommer Brothers responded. 

As a result, staff recommended the sale of select municipal properties be made with controlled land disposition agreements. If the initial projects under these agreements prove successful, it could lead to strategically using additional lots for future controlled land dispositions. This approach allows the municipality to oversee the use of the land even after it's sold, ensuring that it aligns with broader planning goals and community needs.

In January 2020, Council directed staff to apply for the Huron County SLED funding to assist in the preparation of the sale of the lots to a developer, which was successful. The funding assisted in the procurement of a nitrate/hydrogeological study, in addition to covering any engineering, legal or surveying needed to determine what the land can support in terms of development. COVID slowed the process from here. 

In 2021, ACW entered a Memorandum of Understanding with Sommer Brothers, articulating that Sommer Brothers would bring forward a proposal of constructing attainable housing that has passive components with the intention that they would enter into a Conditional Purchase and Sale agreement with the Township. 

In the same year, ACW successfully applied to the SLED fund, on behalf of Sommer Brothers, to assist in obtaining a Feasibility Study that would include the purchase of pre-designed Passive House plans. Sommer Brothers shared their plan with Council, and they successfully entered into an Agreement of Purchase and Sale with the Township in the fall of 2021 to purchase 2 lots (originally three that the Township merged and re-configured to accommodate current set-back requirements).
