The Grade II Listed Beaney Institute was created from the legacy of Dr Beaney, a 19th Century local philanthropist, who wished to provide Canterbury with a museum, art gallery and library. Over the years, there had arisen a clear need to expand facilities to satisfy curatorial and environmental requirements, to improve accessibility and the range of community services offered to the public. In addition, serious deficiencies in the building fabric presented a range of challenges and opportunities to be embraced in the new development plan. The acquisition and demolition of adjoining buildings on Best Lane provided the opportunity to address circulation issues, creating a major new accessible public entrance to the enlarged building footprint. The new entrance leads into a dramatic top-lit foyer space that progresses sequentially, culminating in new library and gallery accommodation. This route engages at right angles with the existing axial corridor approach from the High Street. The reception is located at this important focal point, opposite a glass-fronted lift shaft and open staircase that act as a pin inter-locking the old with the new, bringing coherence to the design. The new accommodation includes a doubling of the library space, the creation of a new temporary gallery and associated education spaces adjacent to the existing upgraded gallery. Listed finishes are renovated generally, with upgraded security of the museum and art gallery spaces combined with improved specialist lighting and environmental controls provided in all exhibition spaces to meet international standards. Other new accommodation includes a café and service / office space for administrative staff and curators. The new extension is designed to achieve a very high thermal performance, and is clad in locally sourced warm red facing bricks, while new clay-tiled roofs match the existing. The existing 19th century façade facing the High Street has undergone substantial architectural conservation, including wholesale replacement of projecting bay windows in natural oak sections, re-bedding of existing terra-cotta ceramic mosaics in lime putty, and renewal of all lead-work.
