Constructing a world class state-of-the-art carbon neutral and BREEAM rating excellent school campus in North Wales

Mynydd Isa Campus is being built to the highest sustainable construction standards, delivering a BREEAM rating excellent certification, and carbon neutral when in use.

Work has begun on the ambitious multi-million-pound sustainable school campus in North Wales.

Built on the site of existing Argoed High School in the village of Mynydd Isa, Mold, the new two-storey campus is to host 43 nursery-age children, 600 primary pupils, and 700 high school students, and will be a shining example of sustainability in the education sector.

The Primary School and High School will remain as separate schools but will operate within a single building with shared facilities.

Once the school has been completed, the former Argoed High School building will be demolished and new games pitches formed.

Flexible spaces

The outdoor facilities have been designed with the different needs of nursery, primary and high school pupils in mind. There will be flexible external play spaces, sports areas, and a flood lit all-weather grass pitch, allowing youngsters to exercise and learn in high-quality outdoor environments.

The school itself is a two-storey building with separate wings for primary and secondary schools, with a shared main entrance area and kitchen.

An extensive series of solar panels lines the roof of the building, providing a substantial amount of the power throughout the Flintshire school.

A first for WEPCo

Mynydd Isa Campus is set to be the first school is Wales to be delivered through WEPCo, whose purpose is to facilitate the delivery of new education facilities (primarily schools and colleges) in Wales using the Mutual Investment Model (MIM) developed by the Welsh Government to finance major capital projects.

A long-term Facilities Management partnership

Robertson's involvement with Mynydd Isa Campus will go well beyond the construction of the school. Robertson will provide Hard FM services for the school once it has been built, meaning that our relationship with the Flintshire school will continue for many years to come.
