The Hydrostone

The Hydrostone is a neighbourhood in the North End of the Halifax Peninsula in the Halifax Regional Municipality, Nova Scotia, Canada. It consists of ten short parallel streets and is bordered by Duffus Street to the north, Young Street to the south, Isleville Street to the west and Novalea Drive to the east.

The neighbourhood was designed by architect Montreal architectural firm of Ross and Macdonald. The neighbourhood draws its name from the special cinderblocks from which the houses were constructed. Most of the dwellings are row-houses in groups of four and six, except for the large, two-storey single-family houses at the eastern end of each street. Some have been converted to sets of flats.

All of the streets in the Hydrostone are boulevards except Stanley Place. These boulevards have treed, grassy strips which serve as communal outdoor space for the neighbourhood. This is consistent with the Garden city movement by which Adams was influenced. All streets are also served by back lanes, a feature not found in most other Nova Scotia communities.

It is designated a National Historic Site of Canada.[1]

Following the Halifax Explosion, many of the wood-frame buildings collapsed on their coal stoves and furnaces and caught on fire, which was a concern when reconstruction was being planned. To minimize the danger of fire, Adams and Ross proposed the use of non-combustible hydrostone for the reconstruction of this area.

Hydrostone was a concrete block that was finished with crushed rock (granite, in this case) to approximate the appearance of cut-stone construction. The concrete blocks and their faces were amalgamated through a hydraulic pressing process, patented by a Chicago firm. Manufacture of the blocks was done in a plant located in Eastern Passage, Nova Scotia and the finished stones were hauled across Halifax Harbour by barge.[2]

Transporting the stones to the construction site was problematic, due to the steep rise from the harbour. To solve this problem and make the area more easily accessible, two diagonal streets were included in the Richmond district reconstruction plans: Devonshire Street/Avenue and Dartmouth Avenue.

The Hydrostone today

Today, the Hydrostone has become a vibrant and desirable area, sought after by young professionals and small families for its ample green space and proximity to shops and transit. Recently, this newer generation has been buying and renovating the area's homes, creating an eclectic mix of the new creative class, along with longtime residents.

In 2011, the Canadian Institute of Planners named the Hydrostone the Second Greatest Neighbourhood in its Great Places in Canada contest.[3]
