Public Space According to Rogers, public space between buildings influences both the built form and the civic quality of the city, be they streets, squares or parks. A balance between the public and private domain is central to the practice's design approach. Buildings and their surrounding spaces should interrelate and define one another, with external spaces functioning as rooms without roofs. It is the celebration of public space, and the encouragement of public activities that drives the form of the practice's buildings. It is the building's scale and relationship with the street or square that helps to encourage public activity and create a people-friendly environment. For example, the steps that lead to the Channel 4 Headquarters, the narrow passage that runs around the Lloyd's of London building, the small churchyard in front of Lloyd's Register, the close around the National Assembly for Wales or the square in front of the Bordeaux Law Courts are all examples where the relationship between buildings and public spaces demonstrate how the architect's responsibility can successfully extend beyond the brief to include the public domain.
Flexibility of Buildings By separating the mechanical services, lifts, electrics, fluids and airconditioning from the rest of the building, inevitable technical developments can be incorporated where they are most needed to extend the life of usable core space. The articulation of the services and core building creates a clear three-dimensional language, a dialogue between served and servant spaces and a means of creating flexible floor space. Standardised large floor-plates with services placed on the perimeter have been successful in commercial buildings and allow for flexible tenancies that respond to the changing demands of the office market. Open ended, adaptable frameworks with large, well-serviced and well-lit floors offer the possibility for a long life span for the building and a variety of possible uses. For example, Mossbourne Community Academy and Minami School will be able to adapt over time to progressive approaches to education. This concept was developed in earlier buildings such as Lloyd's of London and the Pompidou Centre, solutions that include spaces that can be used for multiple activities in the short term, as well as having many alternative long term uses depending on future requirements.
