The new Sir Michael Snyder Building delivers a new boarding facility for the independent secondary Brentwood School, consolidating previously separate boys’ and girls’ accommodation and increasing capacity from 65 to over 120 boarders. 

The campus has evolved over more than 460 years around a sequence of courtyards and quadrangles. Recent projects by Cottrell & Vermeulen have reinforced this collegiate structure and the new boarding house continues this legacy. 

Developed through extensive consultation with pupils, houseparents and staff, the brief prioritised wellbeing for pupils and staff through high-quality, purpose-designed environments. The final scheme provides 123 en suite study bedrooms, a communal dining hall, kitchens and dedicated staff accommodation around landscaped social spaces. As the social heart of the building, it opens onto a secure courtyard and terraced arcade for use in warmer months. 

The building draws on mansion block typologies and early Edwardian Arts and Crafts influences, offering an appropriate scale and character for its context. Vernacular elements – gables, pitched roofs, chimneys, arcades and bullseye windows – give domestic warmth to a larger, repeated structure. Polychromatic brickwork and cast stone detailing introduce depth, variation and an articulation that reflects internal use and adjacency.

Architect’s choices

Brickwork is central to the architectural character of the building, with the main body formed in Ibstock Heritage Red Blend bricks using quarter bond and contrasting Vandersanden Antro, used for polychromatic brick details. Traditional forms evoking domestic qualities are combined with playful and contemporary elements, defining window openings complemented by cast stone plinth details and frieze panels. Prefabricated brick arches form arcades, each integrated into the façade alongside circular openings in hand-laid brick to each stair tower. 

We would like to commend the main contractor, Rooff, and brickwork subcontractor, Global Brickwork, who worked tirelessly throughout construction to realise this complex project.

Specification

The external envelope uses Ibstock Heritage Red Blend bricks, used elsewhere on campus, in quarter bond, with Vandersanden Antro brickwork used to define arches and key features. Cast stone plinths and raked gables contribute further detail. Prefabricated brick and steel ground floor arches form house entrances, picture windows to key internal spaces or linked to form the gallery arcade, with hand-laid contrasting circular brick openings to bullseye windows at each stair tower.

The new block was built to exacting environmental standards. Building services are fully fossil fuel-free, using mechanical ventilation and heat recovery throughout. Air source heat pumps provide heat from a dedicated curved brick energy centre adjacent to the main boarding house, set within the wider landscape setting.

To reduce overall embodied carbon, a composite approach was developed, with CLT forming the upper-storey bedroom modules and a concrete podium slab supporting the larger spanning communal areas at ground level. Features such as a splayed column head and profiled ribbed concrete express the forces within the structure and reduce the impact of punching shear, reducing the amount of reinforcement required.
