TD Tower, office building in downtown Halifax, Nova Scotia, Canada

The TD Centre is an 18-storey office tower at 73 metres in downtown Halifax, bounded by Barrington, George and Granville Streets and linked to the CIBC Building through the Downtown Halifax Link. Its 2014 reconstruction by Lydon Lynch Architects added three floors and 10 metres, roughly doubling floor area to about 200,000 square feet. Photovoltaic cells laminated between glass sheets form sun-shades on the south facade and sidewalk canopies, generating electricity while cutting glare.

The TD Centre opened in 1977, wholly owned by Cadillac Fairview, with about 104,000 square feet of rentable area, mostly offices plus retail space. In 2010 TDB Halifax Holdings announced an east-side enlargement and roof changes adding 10 metres; the project by Lydon Lynch Architects began in November 2012, stripped the building to its concrete frame while occupied, and topped out in late 2014, roughly doubling floor area.

The TD Centre's Granville Street level incorporates the facade of a 19th-century building that once housed a leather harness maker, set into the modern structure. The building remains the Halifax home of the Toronto-Dominion Bank, which signed a new 10-year lease in July 2013 to stay on as anchor tenant.

The TD Centre occupies a block bounded by Barrington Street to the west, George Street to the south and Granville Street on its lower eastern side, in downtown Halifax. It connects to the neighbouring CIBC Building through the Downtown Halifax Link system, so pedestrians can move between buildings indoors. The Granville Street level incorporates the facade of a 19th-century harness maker's building, worth a look on the way past.

The 2014 reconstruction kept the building open while its interior was stripped back to the original 1977 concrete frame. On the Granville Street side, the new base incorporates the facade of a 19th-century building that once housed a leather harness maker. Photovoltaic cells laminated between glass sheets form sun-shades on the south facade and sidewalk canopies, generating electricity while cutting glare on computer screens.
