<h2>About C+W O'Brien Architects</h2>
<p>C+W O'Brien Architects is an Irish architecture and interior design practice operating from studios in Dublin, Cork and London, with team members working across Ireland, the UK, France, Spain and Dubai. That spread lets the firm bring international insight to projects throughout Europe and the Middle East while retaining local knowledge of the planning systems it works within. Its positioning is architecture that transforms cities and builds communities.</p>
<h2>Approach</h2>
<p>The practice specialises in maximising a site's potential and securing planning permission efficiently - a commercially important emphasis in markets such as Dublin where planning risk and delay materially affect scheme viability. It describes a client-centric process that streamlines design to deliver high-quality architecture cost-effectively and on schedule, combining creative thinking with industry knowledge.</p>
<h2>Areas of Expertise</h2>
<ul>
<li><strong>Architecture</strong> - residential, hospitality, commercial and mixed-use buildings</li>
<li><strong>Urban design and masterplanning</strong> - district frameworks and site-wide strategy</li>
<li><strong>Data centres</strong> - mission-critical facilities with demanding power and cooling requirements</li>
<li><strong>Healthcare</strong> - clinical and care environments</li>
<li><strong>Film and TV studios</strong> - production facilities, a specialised and fast-growing sector</li>
<li><strong>Interior design</strong> - fit-out and interior architecture</li>
<li><strong>Conservation</strong> - work to historic and protected structures</li>
<li><strong>Construction</strong> - delivery-stage services and technical support</li>
</ul>
<h2>Modern Methods of Construction</h2>
<p>Modern Methods of Construction (MMC) and Industrialised Design and Construction (IDC) are distinct service lines. The practice designs for offsite and modular delivery, as seen in projects such as Parkside Phase 5B in Dublin and the London Data Centre. Given Ireland's persistent housing supply pressures and construction labour constraints, designing for factory production rather than purely site-based building is a meaningful strategic capability.</p>
<h2>BIM and Digital Delivery</h2>
<p>BIM is treated as a core expertise rather than a documentation method, supporting coordination across complex projects - particularly important on data centres and modular schemes where clash detection and dimensional accuracy determine whether components fit on arrival.</p>
<h2>Research and Innovation</h2>
<p>A dedicated research and innovation strand investigates construction methods, materials and processes, feeding findings back into live projects. For a practice of this size, formalising research is a deliberate commitment to staying ahead of regulatory and technical change.</p>
<h2>Representative Projects</h2>
<ul>
<li><strong>Parkside Phase 5B</strong>, Dublin - modular residential</li>
<li><strong>Fumbally Hotel</strong>, Dublin - hospitality</li>
<li><strong>Rathmines Co-Living</strong> and <strong>Liberties House, Cork Street</strong> - co-living residential</li>
<li><strong>London Data Centre</strong> - mission critical, industrial and modular</li>
<li><strong>Stonehaven</strong> - residential development</li>
</ul>
<h2>Market Position</h2>
<p>The firm competes in the Irish and UK markets across an unusually wide sector range for its size, combining volume residential capability with technically demanding data centre and studio work. Its planning fluency and modular expertise are the clearest differentiators.</p>
<h2>Why AEC Teams Should Know C+W O'Brien</h2>
<p>For developers and consultants working on Irish or UK residential, co-living, data centre or offsite-manufactured projects, C+W O'Brien is a useful reference point for planning-led design and modern methods of construction across the built environment.</p>

<h2>About Sisk</h2>
<p>Sisk - trading as John Sisk &amp; Son Ltd - is one of the largest and longest-established construction groups in Ireland, operating across Ireland, the UK and mainland Europe. The business describes itself as being in the tomorrow business, creating places for future generations, and positions itself around pioneering methods of construction rather than volume alone.</p>
<p>Financially it is substantial: group revenues surpassed 2.75 billion euro in 2024, and pre-tax profits at parent company Sicon rose 62 percent to 58.1 million euro. That scale and balance-sheet strength matter to clients procuring multi-year capital programmes, where contractor insolvency is a genuine project risk.</p>
<h2>Sectors</h2>
<ul>
<li><strong>Data centres</strong> - hyperscale and colocation facilities, a major growth area across Ireland and Europe</li>
<li><strong>Life sciences and technology</strong> - including the Moderna Innovation and Technology Centre in Oxfordshire, with capacity to produce up to 250 million vaccines a year</li>
<li><strong>Healthcare</strong> - including Bon Secours Hospital in Limerick, the first new acute hospital built in Ireland in nearly two decades</li>
<li><strong>Residential</strong> - including Luna and Solar at Wembley Park, named in The Sunday Times Best Place to Live in 2025</li>
<li><strong>Infrastructure</strong> - roads, bridges and civils, including the Killaloe Bypass and Shannon bridge crossing</li>
<li><strong>Commercial</strong> - offices and mixed-use development</li>
<li><strong>Education and sports and leisure</strong> - campus buildings and stadia</li>
</ul>
<h2>Modern Methods of Construction</h2>
<p>MMC is one of the group's three stated differentiators, focused on optimising material usage and streamlining labour to maximise efficiency at every construction stage. With skilled labour scarce across Irish and UK construction, moving work into controlled factory conditions is a structural response rather than a passing trend.</p>
<h2>Sisk Group Businesses</h2>
<p>The group operates several specialist businesses alongside the main contracting arm.</p>
<ul>
<li><strong>Sisk Rail</strong> and <strong>Fuse Rail</strong> - rail infrastructure delivery</li>
<li><strong>Vision Built</strong> - offsite and modular manufacturing</li>
<li><strong>Sensori</strong> - facilities management, extending the group into building operation</li>
<li><strong>Farrans</strong> - civil engineering and construction</li>
</ul>
<p>This structure lets Sisk cover design, offsite manufacture, construction, rail systems and long-term facilities management within one group.</p>
<h2>Sustainability</h2>
<p>The group's ambition is to lead the industry in sustainable management of its operations across their entire life cycle, guided by core values of Care, Integrity and Excellence. It publishes an annual sustainability report and a 2030 Sustainability Roadmap, giving clients and supply chain partners measurable commitments rather than general statements.</p>
<h2>People and Safety</h2>
<p>Health and safety is treated as a governance-level concern, and the group invests heavily in apprenticeships in both Ireland and the UK alongside graduate and experienced-hire routes - a meaningful response to the industry's demographic and skills pressures.</p>
<h2>Market Position</h2>
<p>Sisk competes at the top of the Irish market and as a significant player in the UK, particularly in data centres, life sciences and healthcare, where technical complexity and programme certainty matter more than lowest price. Its group structure and financial resilience are central to that positioning.</p>
<h2>Why AEC Teams Should Know Sisk</h2>
<p>For owners, designers and consultants working across Ireland, the UK and Europe on data centres, pharmaceutical facilities or major infrastructure, Sisk is one of the most significant contractors to understand in the built environment.</p>

<p>This new 4-star Holiday Inn hotel, part of the InterContinental Hotels Group (IHG), is under development in North Dublin, within 1km of Dublin Airport. The design-and-build project consists of a 10-story, 421-bedroom hotel, delivered by Stewart Construction working with an extensive design team, including C+W O'Brien Architects and specialist consulting engineers.</p>
<p>Stewart Construction deployed Evercam time-lapse cameras across the site to record and monitor construction, with BIM integration letting the team track how the build compared to the model as work progressed.</p>
