Lien on Me Mike Holmes
In early 2008, Mike Holmes finished a project that would become a terrific example of modern sustainable building. An unfortunate series of events caused a coupleâ€™s home to be completely demolished, then rebuilt. Holmes used this opportunity to illustrate what can be done using sustainable materials and renewable energy.
Wilkinson Construction was contacted to assist with the construction of this project in various capacities.Read more...
A rainwater harvesting system is featured in this case as part of a plan to capture and re-use rainwater in toilets and washing areas. The excavation was prepared by our company, in anticipation of the large underground tank to be installed beneath the front yard. This consideration could help with overloaded city storm sewers in a drastic way if implemented consistently on a large scale.
Sustainable materials are in part those which can be replenished by nature over a reasonable amount of time. This makes most types of native timber an excellent choice for building. The soffits of this project, both front and rear were made of cedar and installed by Wilkinson Construction. Cedar is naturally resistant to insect damage and rot, not to mention itâ€™s visual beauty after installation.
A project of this nature also requires some of the same considerations as that of a conventional home.
Our ability to bend aluminum on-site to custom fit was needed in multiple areas of this home. Window flashings needed to be constructed to architectâ€™s specifications to cap each window off from the elements. Base flashing was also needed around the perimeter of the entire home, as well as all exterior decks. Different colored stock was used as needed.
Grey steel capping visible on the top surface of walls and railings was fabricated off-site by our company as well. Steel is a better choice in these areas due to width needed and for durability reasons.

Before and After From Dream to Reality
Relaxation here is guaranteed!
This farmhouse had a deck that was in need of a few repairsâ€¦or replacements and thatâ€™s exactly what happened!
The existing deck frame and stairs was becoming rotten and dangerous, thatâ€™s when the ownerâ€™s of this farmhouse near Creemore Ontario, decided it might be time for an upgrade.View Construction and read more...
The proposed plan was to create a two tier project which had an upper deck of around 450 square feet covered by a roof and a lower deck at ground level of around 300 square feet, open to the elements. The owners selected cedar as the material of choice mainly due to itâ€™s longevity and natural beauty.
The new structure, along with itâ€™s roof had to be self supporting to ensure itâ€™s stability. Because of the high water table the footings for this project were super sized to prevent problems with shifting over time. This meant a lot of excavation and a near basement size divot!
Other considerations included an existing covered entry to the basement, which would have to be rebuilt and incorporated into the new design. As this is the only entrance large enough for equipment such as a furnace, it had to be kept accessible. The end result and solution to this problem was a removable railing, pivoting section of floor and two removable panels that allowed people and equipment to move right through new construction into the basement below.
As the project progressed, so did the scope of work and budget. Changes in construction methods had to be addressed as problems surfaced. The deck mysteriously began to grow in size as additions were made. Deck clips were decided upon as the decking began to go down. These completely eliminate any visible nails, increasing the beauty of the cedar and lengthening itâ€™s life.
As the deck went down and the ceiling went up, everyone was pleased with the look and feel of the new addition. Although no stage of construction was without itâ€™s share of hang-ups, everything was worked out in the end.
Hundreds of square feet of finished cedar, tongue and groove pine ceiling and two levels make it a perfect spot to enjoy some summer weather. With itâ€™s many slopes angles and curves this porch is an accomplishment that is both functional and beautiful.Show Less
Sustainable BuildingLow Carbon Development
Wilkinson Construction is working hard to offer you better building methods, materials and systems. Our goal is to offer a much superior product in terms of quality and sustainability in a home. If a high quality of living, on a lowered carbon footprint interests you, please contact us.
Low carbon development is basically a concept for more efficient use of resources in building. Not only are we talking about the building materials themselves, but the whole building envelope including the use of utilities after construction has finished. Itâ€™s all about enjoying a high quality of life and reducing the carbon emissions associated, to a sustainable level.
First, even before the best types of materials are selected, the sheer amount of any material has to be considered. Even a massive use of a renewable resource, is not renewable at all. This is why housing that has a good use of space is more resource friendly in the long run. Not only does it use less material to build, it uses less energy to maintain.Read more...
Carbon and Construction Material
Carbon is emitted in different ways due to construction. Some ways are direct, such as the lifespan of a building. Material wasted is carbon emitted with no benefits at all. If cheap, low quality construction methods are employed, the minimum to pass inspections the building canâ€™t be expected to have a long, maintenance free lifespan. This leads to more costs, more materials and most likely replacement and disposal of many components along the way. In the big picture this building has been built twice over, at twice the cost and twice the use of material. A better use of all this time, money and material would have been to build a high quality lasting structure to begin with. This not only increases efficiency, but in turn also increased the value of the building.
An example of indirect carbon intensive construction, includes materials that require high levels of energy output to get them to a usable form. Remember, that one of the greatest carbon emitting sources on the face of the earth is fossil fuel. When you consider the amount of fuel being burned over a relatively short period of history, this is really no shocking news. Plastics and chemical based materials are good examples of material that uses and includes petroleum in their making.
The bottom line is, materials that are renewable and available such as wood, glass, stone and recycled material should be utilized. Concrete is another good material to choose when building. Although it also required large amounts of energy to make, its ingredients are renewable and well-built concrete structures can have a life expectancy of much more than one hundred years. The use of concrete is much more of an issue that itâ€™s making. When large concrete structure go up, then the property changes hands and the same structures are torn down inside of ten or even five years, that is carbon intensive.
Fuel Related Carbon
More obvious emissions come from the day to day operations of the home. Electricity that the home consumes comes largely from coal burning generation stations. The reason, this is currently cheap, money wise. Cleaner sources of power such as solar, wind and water can reduce emissions caused by the home if they are used in generation facilities. However currently they donâ€™t make up a very large percentage at all. The fuel a home burns directly, is evidently one of itâ€™s largest contributors to carbon emissions. Especially in Canadaâ€™s climate, the largest use of dirty energy is home water heating and space heating. Currently cost effective, this can not last forever. The law of supply and demand dictates what will inevitably happen. Our population is on the rise and our supply will begin to run out. The end of our oil reserves shouldnâ€™t be the concern, itâ€™s the point that production begins to decrease and demand continues to increase. This difference will increase exponentially, most likely resulting in suddenly very, very expensive oil.
There are lots of options that can be implemented in residential construction today that are not â€śnewâ€ť ideas. They may be relatively new to us, but they have been used here for some time, as well as more widespread use in Europe.
Heating and cooling are very important here in Canada due to the wide range of temperatures in the annual cycle. Basic ideas like sunshades and sun porches, with interior doors closed, can shield the home from intense heat in summer. Open areas that let warm air naturally rise to open windows near the top of the home can create a cooling â€śchimneyâ€ť effect inside. In winter, the windows allow solar heat gain into the house and the sun porch is a great heat collector. Other options for low carbon heat are solar and wood.
Wood is considered a carbon neutral fuel, as it absorbs carbon during itâ€™s growing years and releases carbon when it burns. Wood still releases the same amount of carbon if it is allowed to rot, so it makes a good fuel option.
Wood pellets are now receiving increased attention as a viable fuel. They allow waste wood chips, sawdust and other scrap to be converted into a usable fuel. Some of the benefits include low ash production and more consistent low labor heat. The drawbacks are for the most part lack of awareness. Where to get wood pellets and equipment? Where to get service for your equipment? There is still the fact that ash is produced and needs to be physically removed every couple of weeks. Whether it burns in log form, or in pellet form, wood is a good bet!
Solar heat is best utilized when it is combined with hot water. Solar units are available for residential use. These units use ultraviolet light to heat a liquid, which transfers the heat to the hot water units in the house. This allows heat to be generated even on the cloudiest of days. Hot water, or radiant heat can be distributed throughout the home by way of in-floor heating, radiators or forced air with heat exchanger.
In my opinion, a theoretically great system would be a solar assisted, wood pellet boiler setup. The solar hot water provided could be used for space heating and domestic use. The boiler could provide any additional heat required. This would also further improve wood pellet fuel use efficiency.
In order for these types of heating and cooling methods to be effective, we have the rethink one very important thing, insulation and placement of the insulation. Regular stud walls, insulated to R-20 should be a thing of the past. Super-insulated walls that are slow to gain or loose heat will help keep the temperature were we want it. Part of this idea is also creating thermal mass within the structure.
An ideal thermally massive super-insulated wall would be built in this way. A concrete or brick superstructure is perfect for this application and lots of it. Outside this, the insulation is fastened to the external side of the structure, then the siding veneer is added. The concrete structure is insulated from the changing temperature on the outside of the building. The actual concrete wall becomes the same temperature as the indoors. Because of the insulation and the fact that concrete takes such a long time to change temperature, much less heat is lost through the walls. This concept also isolates the wall material. With a stud wall the outside of the stud is cold and the inside is warm, this results in thermal transfer, a building just gives up heat because of the direction of the framing members!
These are just a few good ideas that we can consider when thinking ahead to the future of construction, trying to lower carbon emissions and making better use of resources. Although this seems to make sense, there is plenty of resistance and people with reasons why it wonâ€™t work.
The main reason is of course, money. If it costâ€™s more we are naturally adverse to the idea. Also, the fact that it is a different idea than what weâ€™ve been practicing makes it a hard sell. Sometimes itâ€™s the actual idea of change that seems to be the big hold up. Our current system seems to be working fine at first glance, so why would we change it unless we have to? Well, soon it may no longer be a choice. Why not take the time and plan ahead? It usually pays off.Show Less
