Mynydd Isa Campus, Flintshire

Built on the site of existing Argoed High School in the village of Mynydd Isa, Mold, the new two-storey campus hosts 43 nursery-age children, 600 primary pupils, and 700 high school students, and is 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.

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 array of solar panels span the vast roof area of the Flintshire school, generating a significant portion of the campus’s energy needs. This plays an intrinsic role in the development’s energy efficient strategy and significantly reduces carbon emissions. Additionally, air source heat pumps have been installed to provide heating, contributing further to the site’s overall CO₂ savings.

Carefully aligned with the Welsh Government’s commitment to achieving net zero, the school has achieved BREEAM ‘Excellent’ certification and is fully carbon neutral. The roof hosts 1,080 photovoltaic panels, producing up to 508,987 kWh annually. During peak summer months, up to 600 kVA is exported back to the grid.

Large windows allow for abundancies of natural daylight where necessary to minimise the need for artificial lighting, while measures have been implemented to limit direct solar gain, reducing the risk of overheating and optimising daylight levels throughout the interior.

Mynyyd Isa was carefully designed to enhance the wider Flintshire community, it supports the local economy through job creation and meaningful partnerships with local suppliers. Community involvement is key, with pupils invited to mark important milestones such as signing the steel beams and planting a fir tree to grow alongside them on their educational journeys. With impressive outdoor learning spaces, a play area, and a floodlit sports pitch, the campus prioritises wellbeing, sustainability, and inclusion, reflecting the Robertson long-term commitment to educational excellence and community cohesion.

Mynydd Isa Campus is the first school in 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.

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