Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” -Our Common Future, Brundtland Report 1987

While this bold statement was made over three decades ago, it rings even more loudly today. As we continue to move forward and develop as a society, there is growing need to make conscious decisions to use and consume in a way that is more sustainable. Our choices to live more ecologically must undoubtably extend to the methods we use to add space to our homes.

The construction sector has been one of the biggest offenders when it comes to waste, pollution and energy usage. A recent study by Wrap has shown that over 400 million tonnes of materials are used in construction each year, resulting in 100 million tonnes of waste being produced.

Noise pollution is actuallyone of the biggest factors ona traditional project site.

The commotion of heavy machinery and loud tools is an unfortunate type of pollution we don’t always stop to consider, and everyone in the vicinity is forced to experience the disruption. When you factor in the fuel that is needed to power that equipment, or to transport the equipment to and from the project site- the numbers really start to stack up.

These kinds of waste within our industry made us take a hard look at our own contributions to the cycle. While we knew this level of research and development can be costly, it was an easy decision to make when it comes to our investment in the future of our planet. By taking the steps in developing a fixed design, we have been able to ensure Habattach would be a more ecological offering.

A key component of our sustainable design lies in the QuickBase foundation system. Traditional foundations are extremely heavy by their nature, and require a lot of excavation. When you have to remove large amounts of soil, it has to be taken away a repurposed elsewhere. This process lends itself to causing problems with soil erosion in future. The excavated hole is then filled with concrete, a substance known for being a carbon-heavy culprit.

In stark contrast to its traditional counterpart, the QuickBase foundation for the Hab offerings requires minimal excavation and no heavy machinery.

The part-recycled plastic ground beams are filled with non-shrink grout to give a high strength composite beam. The beams are then connected via a series of push-fit joints to form a frame that carries the load of the Habattach through the piles through to a suitable bearing strata. Selecting this foundation as part of our fixed design eliminated the need for mass concrete foundation.

Thermal efficiency was another vital element in our design process for Habattach. Selecting better quality insulation and using it the right way, makes all the difference. By creating a complete envelope of insulation, your Hab is 2.5-3 times more efficient versus a new masonry build. Simply put, the Hab uniquely conserves energy!

To us here at Habattach, best practices means green practices! Prefabrication off site means less disruption and less noise pollution. The sizing of our offerings and ordering of materials are purposeful. By designing the Hab to be as tall as the material we purchase, this means we increase efficiency in production and have less waste as a result.  Sustainability isn’t just a selling point. With Habattach, we know it is important that all our raw materials are UK based, and sourced from certified sustainable forestry.

Man power is another component that can have a negative impact on our carbon footprint. Deliberate planning in the design stage has given us the opportunity to streamline site deliveries and the number of team members needed for installation. When you compare the ecological impact of having even two men on the job for 14 days versus 100 days, the positive shift is significant.

One of our favourite parts of the Hab design process was in selecting the Sedum green roof. Not only does this newly created ecosystem on the roof of your Hab look visually stunning, but you are actively encouraging new wildlife. The roof has a mix of 9 varieties of sedum, from Hespanicum, a great allrounder loved by bee’s, to Alburn Coral carpet, with great winter colour and a must for the butterflies.
