National Aquatic Centre

Sports Campus Ireland, Dublin
Full Architectural Services
16,000 m2

This spectacular facility was developed around the need for international standard swimming facilities to accommodate the Special Olympics, held in Ireland in 2003. The competition pool hall features a 50m pool with floating floors and two booms, a diving pool also with floating floor and seating capacity for 2500 spectators. There is an indoor leisure pool and a gymnasium with fitness and training suites.


The building was procured and delivered to an extremely challenging programme in order to be ready for the event.


Landmark sports venues provided for one off events can quickly become unsustainable in the longer term if a viable business strategy is not considered at the outset. National Aquatic Centre is one of the largest indoor leisure pools in Europe and has continued to be one of the country’s most popular visitor attractions right up to the present day.

Greystones Sports Centre

Wicklow County Council
Full Architectural Services
3,600 m


Greystones Sports Centre was developed in tandem with Bray Sports Centre to meet the leisure needs of northern County Wicklow.  The brief was to provide a range of facilities to serve the community, comprising two swimming pools, gym, studios and indoor sports hall as well as a cafe, small library and community rooms.

Family Orientated Experience

This ambitious project was conceived to provide a range of wet and dry sports activities for the community of Greystones.  To avoid duplication of facilities with those at Bray, the swimming pool offers a more family orientated experience with confidence water and a more expansive learner area to suit a wide range of swimming abilities.


The building is organised as three distinct forms – a double height pool hall space with two storey secondary and ancillary functions to the rear, a double height sports hall with ancillary accommodation and a ‘link’ element joining all the spaces.


Demesne’s feasibility study secured maximum grant funding for the project.

DCU St Patrick’s Sports Grounds

DCU Sports Grounds, St Patrick’s
Full Architectural Services, Dublin
18,000 m


The development comprises a major upgrade of the playing fields at St Patrick’s Campus to maximise playing potential and use enhance student experience in a location where available space is at a premium. The new facilities include a full size artificial grass GAA pitch as well as a natural grass training space with floodlighting and landscaping works.

This project forms part of an ambitious long-term capital development plan to transform Dublin City University across its multiple sites providing a platform to realise its ambitions in research, teaching and learning, student experience, sport and enterprise engagement. St Patrick’s Campus had already been greatly enhanced with the provision of a new library, teaching space, recreation and sporting facilities.

Introducing floodlighting in to a built up residential area was very challenging due to the need to attain design lighting levels on the playing surface with minimal margins around the pitches to ameliorate light spill to adjacent sites. The issue was overcome by using the latest LED technology with detailed modelling and assessment of lighting performance to demonstrate that the planning constraint of no increased levels of lighting to surrounding properties could be achieved.


The project was delivered under the Public Works Contract for Building Works designed by the Contractor. The project was completed in Q4 2020 and has proved to be a significant enhancement of the University’s overall sports provision.


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.

Demesne partnered with GT3 architects in the UK and delivered the post planning stages of the project.

Fast Track Design & Build Contract with Tight Budgetary Constraints.


The project was developed under a Design & Build Contract with the main Contractor, Wilmott Dixon Construction, a large UK based construction firm having been appointed by the client, Stockport Council. Budgetary restrictions and a keen time frame presented various challenges.



Demesne were available to their client, Wilmott Dixon through the lifecycle of this development and travelled to site fortnightly for over a year to ensure on hand and on demand input to this project to ensure a quality product was delivered in line with the brief and budget. This was achieved. The development was handed over successfully to Stockport Council in February 2018 .

Bray Sports Centre

Wicklow County Council
Full Architectural Services
2,800 m


The Bray Swimming Pool and Sports Centre was developed alongside Greystones Sports and Leisure Centre to meet the leisure needs of northern County Wicklow.  The brief was to provide a range of indoor and outdoor sports, comprising two swimming pools, gym, studio and astro soccer pitches to complement the more family and leisure orientated experience on offer at Greystones.

The building is organised as two distinct forms and features a stunning glazed elevation with bespoke brise soliel.


The double height pool hall adjoins the two storey ancillary block containing changing facilities and gymnasium.


The outdoor element of the scheme includes 4 5-a-side 3G pitches. Ease of operation and maintenance were critical components of the brief.  In addition to an efficient thermal envelope and heat recovery, the use of CHP (combined heat and power) benefits the operation of the building by helping to reduce energy costs.


Demesne’s feasibility study secured maximum grant funding for the project.
