About us

Quintain is one of the largest mixed-use developers in Ireland, with a landbank that can accommodate over 9,000 residential units and over 300,000 sqft of commercial space.

Who we are

Our vertically integrated team has vast experience in every aspect of property development, construction and finance enabling us to plan, create and deliver innovative and forward-thinking communities that improve the standard of living in Ireland.

Since 2016, we have delivered over 1000 homes within our Adamstown and Portmarnock neighbourhoods. Our team works across all stages of housing delivery, from acquisition to master planning, design and construction through to sales and marketing. 

With the existing Irish portfolio, Quintain is the third largest residential mixed-use developer in the country. Adamstown can accommodate approximately 4,800 homes across 200 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 UK 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.
