“ Each floor has a balance of closed and open workspaces with ‘light’ and ‘dark’ areas to suit all work activity. CPMG ARCHITECTS BUILDING ARRANGEMENTS The building was located on the northern part of the site because of the view from the vehicle access point and the building being surrounded on two sides by an existing tree belt. This was reinforced to provide sheltered external spaces for work and leisure, a vital ingredient of the design ethos. The front entrance is identified by flags, the reception clearly visible from the outside and on entering the building the atrium and stairs are immediately in front of you to provide easy access. As the atrium lies at the heart of the building, breakout and communal working areas were located closer to the atrium and meeting rooms and social working areas were located on the ground floor. Each floor has a balance of closed and open workspaces with ‘light’ and ‘dark’ areas to suit all work activity, alongside 320 fixed desk positions. SUSTAINABILITY The building was designed to be both low energy in use and sustainable by adopting an unconventional approach based on the principles of Passivhaus. The building incorporates: • Exposed thermal mass • Super insulation • Good airtightness • Maximum daylight with external shading to control solar gain • Displacement ventilation providing high volumes of fresh air at low velocity • Openable windows • Rooftop PV array • Rainwater harvesting • EV charging points DESIGN FEATURES The interior of the building is warm in character with an earthy and organic colour palette– using materials such as timber, concrete, stone and metal - to represent a company that is centred around agriculture and to create an energising and sensory environment. The exterior contrasts this with a formal, crisp and timelessly modern design. There is great elegance to how external solar tracking glass fins move to control the sunlight, opening and closing and causing the building’s appearance to change throughout the day and again at night. The extent of the views that can be seen from within is impressive, with the fins adding complexity to the scenery through their inter-reflectiveness, creating intrigue as well as alleviating the need for internal blinds that can disrupt the connection of staff with the outside world. The internal environment provides a mixture of formal desking areas, meeting rooms, telephone booths and a large amount of flexible space designed to encourage people to circulate within the building. The ground floor is shared, containing a restaurant, a separate coffee bar and meeting rooms. The building also has opening windows at the upper floors and huge sliding doors at ground level, increasing the connection to outside from within. Circulation between floors is via an open staircase which acts as a unifying feature, enabling the entirety of the building to be perceived and understood from a single location. It also encourages physical interaction between staff members of all levels at every opportunity. PAGE 19 - ARCHETECH
