Decathlon Ireland, Dublin
Full Architectural Services
6,000 m


Demesne Architects led the design team for the delivery of a new flagship retail warehouse for sports goods retail company Decathlon, at a landmark site in North Dublin.  The store is also Decathlon’s business headquarters. The brief included 4000m2 of retail floor space, over 700m2 of office accommodation for the administrative operation as well as indoor and outdoor sports play areas, parking, landscape works and site infrastructure.


As this was Decathlon’s first store in Ireland it was necessary to establish a new supply chain.



The team delivered the building to the required quality within an ambitious 7 month construction programme that at the same time remained true to the concept and brand values of the Company. To achieve all of these outcomes required close collaboration between the design and construction teams with Decathlon retail partners and teams in Ireland and France.

Enhanced Customer Experience

Living Wall and Sustainable Environmental Design


Design features for the project include a large green ‘living wall’ feature over the main entrance in addition to an enhanced landscaping scheme to welcome customers and promote strong synergies with nature. Environmental sustainability was at the heart of the project with over 20% of the building’s energy provided from renewable sources, enhanced biodiversity for the site landscaping and a target BREEAM rating of Very Good.

SPADE Shared Kitchens

SPADE Enterprise Centre, Dublin
Full Architectural Services
500 m


SPADE  is a community based Enterprise Centre, originally opened in 1990 in the converted St. Paul’s Church, North King Street, which is a protected structure. Demesne have designed & submitted for planning, Phase  Two, which is an extension that will increase the existing shared kitchen provision and will allow its members to use a full commercial kitchen, providing start-up & small scale food businesses an opportunity to grow their business.

The SPADE initiative assists local unemployed people to successfully set up their own businesses.

From the outset this venture has proved very successful and within a short time the building was fully let.

The new extension will allow members using the open plan kitchens to operate side by side in a cohesive manner. A major part of this development is to encourage networking and the spaces will operate in a way in which visitors and members can interact. The site is challenging, as it is land locked site with restricted access and is bounded with high density residential units. The site has archaeological importance and houses a valued historical Protected Structure, the former St Paul’s Church.
