When building this home, Keogh Construction put extreme thought into the design and the products used throughout each stage. Each product was evaluated based on their company’s pillars: healthy home, low embodied energy, ability to be recycled/reused, durability and resiliency, affordability, locality, ability to enhance biophilic design, and whether or not it was Reimagined (reclaimed). Each of the features below where specifically chosen to align with our company’s values. For more information on our pillars, visit the Reimagined tab on our website.


  • Fireplace surround: The fireplace stone surround was reclaimed from an old foundation in Toronto making it a one of a kind feature. Before this stone was a foundation in Toronto, it was originally sourced from the Humber River. 
  • Exterior stone:The natural stone wrapping around the exterior of the home was previously bedrock which was removed to build a home in Mono, ON. Instead of discarding it after excavation, Keogh Construction decided to reclaim it and featured this stone for everyone to see. 
  • Maibec wood siding: Not only is this siding manufactured in Canada, it is recyclable at the end of its lifespan and enhances the biophilic design of the home. 
  • White oak flooring: Harvested and crafted in Ontario, this flooring is durable and only made from wood taken from managed forest. Finishes are 99% free of VOCs and formaldehyde.  
  • Vicwest steel roofing: Not only is this steel roofing durable and recyclable, the colour of the roof was chosen to reflect solar radiant heat away from the home, decreasing the cost of cooling in the summer. This roof also comes with raised seams to allow for the attachment of photovoltaic (PV) panels. 
  • HanStone Quartz Countertops: These Ontario made countertops are not only produced local, but contain extremely low levels of VOC’s. Quartz products typically contain higher VOC’s due to the resin used as the binder. 
  • Powder room and ensuite countertops: These stunning countertops were purposely bought as  cutoffs locally to eliminate the additional manufacturing and transportation required when ordering a new product. 
  • “Natura” primer and paint and caulking: Not only is this paint free of emissions and VOCs, it is also certified asthma and allergy friendly. The interior caulking used is also 100% VOC free.  
  • Stair Feature Wall: By reusing old flooring from a previous job, we were able to create this eye catching feature wall that enhances the biophilic design of the home. 


  • Passive solar design: Orientation and amount of glazing were important in the design of this home. With the majority of the windows on the southside, the main living areas are positioned to receive the most natural light. The sun is high in the summer and low in winter. Window overhangs were designed to decrease overheating in the summer while still allowing for solar heat gain in the winter.  
  • Double stud walls: Consisting of two framed walls built next to each other, double stud walls allow for increased insulation and an airtight barrier. Double stud walls allow for an increase in R-value (R=42) and a decrease in thermal bridging. 
  • Triple pane glass windows: These windows are more energy efficient and filter out more UV rays than double pane windows. Triple pane also help provide a consistent temperature within the home regardless of the season.
  • Stone wool insulation: Made from 40% pre-consumer recycled materials, stone wool insulation is a green alternative to high density spray foams, XPS and EPS insulation. 
  • Under slab radon protection: Radon is a gas produced by the breakdown of uranium found in soil and through chronic exposure cause increase the risk of lung cancer. The design of  Radon Guard Insulation (R=16) directs radon gas that has entered the sub-slab and exhausts it before it enters the home.  
  • SIGA interior and exterior barrier systems: These barrier systems help create an airtight building envelope increasing energy efficiency of the home. It does this while simultaneously controlling the diffusion of moisture to ensure moisture is not trapped within the building envelope. 
  • Electrical panel location: The electrical panel was purposely placed in the garage since electrical breakers give off large amounts of electromagnetic radiation which is harmful to the body. One way to reduce EMF radiation is to move the panel as far away from living and sleeping areas as possible.
  • VanEE Gold Standard HRV Unit (G2400H EMC): This energy efficient HRV system allows you to ventilate indoor air at a low operating cost. Ventilated air contributes to a healthier home by removing moisture and pollutants from indoor air and replacing it with fresh temperature calibrated outdoor air.


As a company Keogh Construction believes in going above and beyond to build homes that are sustainable and that take into consideration the construction industry’s impact on the environment. We take extra steps to ensure homes remain comfortable and functional despite our climate’s extreme fluctuations in weather. Learning from our 22 years of experience, we have researched, tested and redesigned our processes, allowing us to create a new standard for how we build into the future. We are Reimagining the way we build which can be expressed within our company’s values and pillars of sustainability:

Passive Solar Design: We study how to reduce greenhouse gas emissions through the use of natural and free energy from the sun for heating and cooling homes. We do this by considering where and when the sunlight hits the building, and choose building materials to either reflect, transmit or absorb the sun’s rays.

Biophilic Design: We recognize that humans are intimately connected to nature. We use this architectural approach to ensure that the environment inside the home respects and takes advantage of the cognitive, physiological and psychological benefits of nature to complement and enhance this connection. This includes the careful use of natural materials, like wood and stone, as well as considering the cycle of humans and nature.

Healthy Home: Our homes are designed, constructed and renovated using methods and materials that are carefully chosen to proactively improve the health and well-being of those living within it. We take into consideration and strive to eliminate exposure to potential mold, volatile organic compounds (VOC), radon, radiation and materials that off gas.

Low Life Cycle Impact: Through careful design and sourcing, we aim to use products with low embodied energy to reduce the environmental footprint of the building. We also attempt to seek out materials that require low maintenance during their lifespan and those that can be reclaimed or recycled when no longer needed to decrease future contributions to landfills.

Durable and Resilient: By using durable materials, we are decreasing the use of raw materials, energy and production of greenhouse gases that would otherwise be associated with more frequent replacement of less durable products. We also carefully consider designing and building houses that maintain or regain functionality and vitality after stresses or disturbances (manmade or natural).

Local: We aim to use local products in our construction in order to support the community, reduce our carbon footprint, and ensure the product manufacturers are adhering to the same environmental guidelines that we are familiar with.

Affordable: Ensuring products are affordable to the average consumer is important to us therefore we take the time to find a balance between products that follow our sustainability goals and making sure they are priced fairly.

Reimagined: When applicable, we salvage previously used building materials which would otherwise enter landfill sites such as reclaimed bricks, hardwood and stone. Any materials that are not suitable for our projects are donated to local charitable organizations that benefit from selling used building material.
