Built in 1913, the landmark Bloor/Gladstone Branch project of Toronto Public Library is a renovation and addition to a listed heritage property in downtown Toronto. The 20,627 sq foot facility was renovated to bring the library into the 21st century with a building that is over 9,000 sq feet larger, accessible and supports modern library services while, at the same time, treasures the past. The building is not only more welcoming, it is more sustainable too with the Library’s first green roof. The new glass addition with a two storey curtain wall provides a dynamic street presence. To maximize public space, a floating glass cube for staff was added which includes a film depicting photos of the trees that had to be removed during construction. An outdoor enclosed reading patio from the children’s area was also added to create a quiet oasis. The height of the ceilings with the large original arches creates a feeling of space to the extent that even when the place is packed and all seats are taken, somehow it doesn’t feel crowded.
