The phase 3 masterplan can be split into four main proposals:

1. Retrofit of the Bungalow building to provide a new consolidated Estates and Facilities hub housing office and welfare space for the team.
2. Retrofit of Suffolk House to provide a new home for the music department with direct links to the Lees Hall auditorium for performances.
3. A new state of the art Sixth Form Centre & senior school classroom space to cater for growth in our senior school numbers.
4. Significant landscaping enhancements to create a new garden and improve existing site links. A new vehicular access from Cheam Road to improve safeguarding by separating vehicles from pedestrian access into the main school entrance.

Full deep green retrofit of the existing Victorian house building to create a new Music Centre and performance garden located next to the existing Lees Hall auditorium. The proposed scope of works includes:

• New like for like high performance timber / recycled aluminium composite windows throughout.
• Internally insulate using natural wood fibre insulation, recycled gypsum boards and breathable clay plaster.
• Replace existing gas boilers with Air Source Heat Pumps
• New covered School site entrance to improve accessibility and better connect the building with the Lees Hall auditorium and the rest of the School site.

The proposed new building helps to reinforce the subtle bookend massing of the historic School buildings provided by the existing Refectory building massing to the west of the site. In response to the different site environment to the north and south, the new building teachings spaces are arranged to suit their outlooks.

Those facing north provide more formal teaching spaces, with more controlled environmental performance to

recognise the acoustic constraint of facing the busy Cheam Road. To the south more open, collaborative teaching space can be achieved with the opportunity to open up and bring the School’s landscape and gardens in. The south facing accommodation is separated to create a series of inside / outside courtyards bringing the School’s rich landscape into the building and blending the realms of learning and nature.
