Haberdashers Aske School for Boys provides education for ages 4 up to 18 at its site in Hertfordshire. Originally dating from the 17th Century, the school has evolved over time, now occupying a large parkland campus. The successful pre-prep school was formerly located off site, and this project was conceived to provide a dedicated new home for it within the central campus. The historic setting of the site and proximity to open countryside and an airfield meant Planning was especially challenging to secure.
The project was for the design and construction of a single story pre-prep school, comprising of classrooms, an assembly hall and external landscaping. The School’s aspiration was the development of a very low energy building providing a high level of occupant comfort with the use of sustainable materials.
A fabric first approach was adopted to optimise daylighting whilst controlling solar gain. This included installing high levels of insulation and stipulating an airtight construction, to reduce heat loss through external fabric whilst optimising a ventilation strategy providing greater indoor air quality with heat recovery. The principal structure was formed in a CLT construction, requiring a high degree of services coordination to pre-form builders-work holes for off-site manufacturing. External lighting and services were carefully planned to comply with Planning conditions. A large new car park equipped with Electric Vehicle chargers was built at the north of the site.
The resulting project delivers a bright and welcoming space, transforming the pre-prep offering for the school in its new home.

William Morris Primary School
Construction of a new extension to the existing school and remodeling of existing classrooms to provide new facilities. The extension was to replace the mobile classrooms at the rear of the school to provide permanent accommodation. The extension includes three key stage 2 classrooms, staffroom, and associated support and teaching spaces. Outside includes new hard and soft landscaping works, play area, and additional car parking. The project aims to help meet increasing demand in the local area for school spaces.
CBG Consultants worked closely with the architect during feasibility stage to assess various schemes for the extension and remodeling to arrive at a preferred option. A report was issued following a site survey for the M&E services to make sure all the equipment and services complied with building regulations and standards. Areas of non-compliance were highlighted and was addressed as part of the overall scheme. A BRUKL document was compiled as per the Part L building regulations to assess energy performance and carbon emissions for the project. This is to make sure that the building complies with sustainability targets set out by the England Building Regulations Part L 2013.
St Paul’s Cathedral School
St Paul’s Cathedral School is a co-educational preparatory school for boys and girls aged 4 to 13 and a residential choir school for the boy choristers of St Paul’s Cathedral.
The school identified a need to increase capacity and improve its facilities to its pupils. The project included building a new boarding house, which was to provide accommodation to reflect current regulations, with the desire to exceed the expectations and to secure the culturally significant English Choral tradition for future generations. The accommodation, running over two floors, includes 36 beds, common rooms currently configured as a games room and cinema room, bathrooms, plus ample quiet social spaces. The building also included residential staff accommodation, more classrooms, ICT suite, an enlarged and refitted dining hall and kitchen and bespoke play equipment.
CBG Consultants was appointed to provide M&E design and sustainable consultancy services for the project. The CLT extension provided a good opportunity to reduce energy costs through high insulation and low infiltration rates inherent with the timber panel building system. The building was modelled to test overheating and the detailed design incorporated feedback from the modelling including optimising glazing selection and variable ventilation rates within the spaces to mitigate both occupancy numbers and summer overheating.
The boarding house design faced the problem of requiring adequate fresh air, avoiding overheating, and keeping out road noise and pollutants whilst being connected to a Grade 1 listed building. Large air conditioning plant was ruled out in favour of opening windows supported by discreet ventilation units, co-ordinated into the building design.
The design team recognised the location significance and the planning conditions concerning internal air quality. Mechanical Ventilation and Heat Recovery Units (MVHR) were provided locally for each boarding room and communal spaces, running at continuous low speed operation with boost triggered by air quality sensing. Final filtration included NO2, PM2.5 and PM10 modules.
