About Quintain

Who we are

Quintain is one of the largest mixed-use developers in Ireland, with a landbank that can accommodate over 9,000 residential units and almost 95,000 square metres of commercial space.

Jointly led by Eddie Byrne and Michael Hynes, there are currently 21 experienced employees on the Quintain Ireland team. The team is expected to grow to over 40 next year and will manage a range of local construction partners. The Irish team will be fully integrated with the wider London-based team.

Since 2016, we have delivered 800 homes within our Adamstown and Portmarnock neighbourhoods. Our experienced team works across all stages of housing delivery, from master planning, design and construction through to sales. 

With the existing Irish portfolio, Quintain is the third largest residential mixed-use developer in the country. Adamstown can accommodate approximately 5,000 homes across 220 acres of land, with further land at the neighbouring Clonburris site, to build approximately 350 houses; the recently acquired Cherrywood site is 120 acres and has an expected capacity of 3,000 homes; and the 87 acres in Portmarnock has the potential for 1,000 homes.

Quintain was established in London in 1992 and has developed significant expertise in leading major regeneration programs. The company was floated on the London Stock Exchange in 1996 and was taken private in 2015. Today, Quintain is developing Wembley Park, one of London’s most exciting new neighbourhoods, which contains, hotels, playgrounds, 70 shops and restaurants, a multi-screen cinema, theatre, public spaces and will have over 10,000 homes when it’s complete. 

Our ambition and strategy

We are a leading large-scale developer,  whose ambition is to create exceptional and affordable places to live which are at the forefront of sustainability, design, and placemaking for our communities. 

To deliver this ambition, we are currently working across four locations in Adamstown, Clonburris, Portmarnock and Cherrywood. Across these locations, we will deliver 9,000 homes, retail and leisure amenities. We have provided for six schools, two local sports facilities with all-weather pitches and approximately 80 acres of parks. Most importantly, all our locations were chosen for their efficient transport links.
