Project Description

Cedar Brook Dublin

Dublin’s conventional suburban “semi-d” has often been quoted as an unsustainable solution with a need for greater housing density and affordability required. Cedar Brook, originally developed in 2003, provides a radically different affordable housing scheme, billed at the time as ‘the first of its type’ in Ireland and a ‘model for housing developments throughout the country’.

A joint venture by Park Developments, John Sisk & Son and Dublin City Council, it contains 374 apartments and terraced houses on a 10-acre site in Cherry Orchard, giving a remarkable density of 37 homes per acre. It is unique in many ways but particularly, it was aimed at providing housing on a fast-track basis using new construction methods. At the time these were the least expensive homes on the Dublin Market but with a very high specification being provided.

Recipients of the RIAI Irish Architecture Award 2004 for this development, O’Mahony Pike Architects designed Cedar Brook as no conventional Irish housing estate. The scheme is laid out in five terraces around a landscaped central park with a pedestrian promenade running through the centre. Most of the buildings are three or four storeys, with apartments at ground and first floors and duplex townhouses above.

The 4 storey terraces are designed to replicate  a traditional Victorian  Dublin model with repeating bays of 6 own door apartments  and duplex units, each served by a single external stairway with small feature Apartment buildings bookending each terrace.  The 3 story terrace has a traditional house at ground and first floor with an apartment at third floor accessed via a feature stairs. Over 200 dwellings have private rear gardens with the balance provided with large terraced balconies

A number of different products were chosen and these, as stand-alone products, were not innovative but all together provided a new and innovative project.

Amongst these the choice of Hot Dip Galvanized steel throughout the development stands out as a very significant feature of this innovative thinking. It works on many levels, not all of which are immediately obvious but all of which contribute to the sustainability of both the design and the development itself and were carefully considered in the design process.

Unique Characteristics

Faster Construction

One of the advantages of hot dip galvanizing is the speed at which it can be processed in a factory controlled environment which then arrives on site complete and ready for erection with no further finishing required.

All Galco galvanizing plants offer a guaranteed turnaround service with 80% of material being processed within 3 working days of receipt.

Toughness and Strength

The Hot Dip Galvanized coating is not like any other coating available. It is metalurgically bonded to the steelwork and the combination of zinc-iron alloys provides a tougher and more abrasion resistant coating than steel itself. This allows it to be easily erected without the need for touching up afterwards as would be the case with painted finishes.

Durability

Another key feature of Hot Dip Galvanizing is its durability. Not just because the coating is so tough but also because zinc corrodes at a very slow rate of approximately 1 micron per year in an urban setting. Given that most of the steel in Cedar Brook would have coatings well in excess of 85 microns, this ensures that the staircases, balconies and many items of street furniture will last in their present state for another 50+ years.

Maintenance Free

One of the other key benefits of such a long life is the complete lack of maintenance required. This development is already 14 years old and while it will be necessary to re-paint much of the concrete structures no such maintenance has been, or will be required for the steelwork, at any stage in the next 50 years.

Sustainability

Hot Dip Galvanized steelwork provides a fantastic opportunity to bring two naturally abundant materials, iron and zinc together to offer one of the most sustainable building materials available. Zinc is present is soil, plant and animal life and it has been acknowledged in an EU risk assessment that galvanized products pose ‘no threat to the environment’.
