The school has been design to achieve BREEAM rating of 'Outstanding'. A score of 87.64%. The project will be the first primary school in Wales to achieve BREEAM ‘Outstanding’ and is one of three primary schools in the UK to achieve the standard.

The design of Ysgol Ffwrnes had sustainability at its core.

The two-storey building provides 17 classrooms, specialist rooms, community rooms, two separate play areas, all-weather MUGA and external teaching areas. These amenities are open for access by the surrounding community out of school hours.

The school’s imaginative design provides a variety of stimulating learning spaces. Arranged over two stories the design maximises the views to the nearby coastline whilst minimising the building footprint. Courtyards, covered classrooms and a roof terrace have immediate links to classrooms and the ecologically rich woodland setting.

We installed a 20,000 litre rainwater harvesting system to collect rainwater from the roof to provide water for flushing the toilets. The tank capacity when full is enough to cover over 4000 flushes. We have installed 16m² in total of solar panels which are used to preheat the water temperature going into the hot water storage cylinders.  On sunny days the solar panels will generate enough output so that the school won’t require any other form of heating for the hot water.

WRW formed wooded walkways around the school to provide learning environments for the pupils including external planting areas. We have built a pond and dipping area. We carried out an extensive pre-commencement ecological assessment which included relocating newts and adders.
