Two recent upper educational projects by Boston's Ann Beha Architects highlight the two predominant approaches to dealing with new interventions inside and beside historic buildings. The Music Building at the University of Pennsylvania in Philadelphia creates "a dialogue between old and new," while the renovation and restoration of the Diana Chapman Walsh Alumnae Hall at Wellesley College in Wellesley, Massachusetts blurs the distinction between old and new.
Penn's Music Building roughly doubles the existing square footage, basically twinning the old building to create a new whole. The architects analyzed "the [existing] façade and massing organization, setting datum lines, proportions, heights and configurations, as a framework for the exterior design expression." Where the existing is red brick, the new is a terra cotta rainscreen with horizontal fins and full-height windows, the three working together to give the impression of punched openings. A shift in the rainscreen's surface relates to the existing building's subtle differentiation between the lower and upper floors. Lastly a projecting cornice corresponds with the line of the old roof, but its wrapping down the sides is clearly contemporary.
In the process old layers were discovered and were then brought to light, such as murals and windows. So differences between old and new may be slight and hard to distinguish, but the result is certainly brighter and more open, the latter both in terms of accessibility and the effects of new surfaces like mirrors.
It's clear that each approach by Beha is appropriate: Penn's old building does not require a literal twin, but a new mate that "speaks" with it and respects it; Wellesly is a minimal renovation that expresses itself as subtly on the exterior (image at left) as it does inside.
