Treowain Enterprise Park, Machynlleth - a net zero carbon project
13 Sep 2022

SWG Group has started work on extending the Treowain Enterprise Park in Machynlleth, Powys.

We have started works on site in August but have been busy designing and planning this project for many months.

It is a net zero carbon project and while SWG Group does everything we can to complete projects in a way that is as sustainable as possible, this takes it a step further.



As usual, we are working with designs and materials that are sustainable, robust, low maintenance and durable - ensuring minimal maintenance required to ensure the project has a net zero carbon footprint.

However, we go further - instead of Ordinary Portland Cement, SWG is using Ground Granulated Blast Furnace Slag (GGBS), a by-product of iron and steelmaking and so has virtually zero CO2 associated with it, and we are using fibres as alternative reinforcement products instead of steel bars and mesh, again reducing CO2 levels.

Furthermore, there will be air permeability testing and thermal modelling carried out to ensure all materials used will satisfy regulations for building, glazing and doors. A large photovoltaic array will also be implemented as part of the scheme. 

Another way the project is achieving carbon zero status is by SWG encouraging car sharing and using a vehicle tracker system to monitor speed and distance travelled of low emission company vehicles to reduce

carbon footprint.

Project specifications

The project is for the Welsh Government and includes creating one unit of approximately 620m² floor area including mezzanine for single occupation.

The other unit will be divided into two equal units each with a floor area of approximately 460m².

As well as the building work, SWG Group will also create car parks, paths, landscaping, drainage and services connections.

Making a difference 

Once completed, the new units will be rented to local businesses. 

SWG Group is proud to begin work on delivering this exciting and important project.  It will have a huge impact on the local economy and employment options alongside having very little environmental impact, so we are excited to make a difference in Machynlleth like this.
