Stronger together: MCA Architects and TTSP HWP become Hyceon
For you, the essentials don’t change: the same people, the same standards, the same commitment to your project. What changes is what we can now do for you — 270+ specialists across five European cities, covering every stage from site selection to handover. And our architecture beyond data centres — workplace, commercial, healthcare and community — continues as part of Hyceon’s heritage practice.
What Hyceon adds
One integrated European team
270+ specialists across five European cities, working to one standard in the local language of every market and authority.
The full project lifecycle
Advisory and due diligence, planning and permitting, architecture and master planning, MEP and civil engineering, sustainability and ESG, and client-side project management — one accountable partner from first site visit to handover.
Deep engineering and permitting strength
German general-planning discipline and a proven European permitting track record now sit directly behind every MCA design.
Greater capacity for complex projects
More than 10 gigawatts of data centre projects assessed, designed and delivered across the group — capacity for the largest, most demanding European campuses.
Sustainability leadership
Energy, water and carbon performance engineered in from the first decision, designing to targeted PUE benchmarks of 1.2 or lower and aligned with the EU Taxonomy — our Blue Future in practice.
Built on MCA’s experience
Founded in Dublin in 1988, MCA Architects grew from one of Ireland’s most established architectural practices into a trusted design partner for the world’s largest technology companies — with more than fifteen years of hyperscale and colocation experience, over seven million square feet of data centres designed, 2.6 gigawatts of critical IT load, and 130 hectares of campuses master planned across Ireland, the UK, the Nordics, Germany, Switzerland and Spain. That experience is not being replaced — it is one of the foundations Hyceon is built on.
Beyond data centres: MCA’s commercial, workplace, healthcare, retail and community architecture continues within Hyceon as our heritage practice, led by the same Dublin team. If your relationship with MCA is outside the data centre sector, nothing about how you work with us changes.

Frequently Asked Questions
Yes — as part of Hyceon. In 2026, MCA Architects and TTSP HWP united to form one integrated European practice for data centre design, engineering and advisory. The MCA team, Dublin studio and expertise all continue within Hyceon, and existing agreements and legal arrangements are unaffected.
Nothing changes. Your project team, your points of contact and your existing agreements continue exactly as before — the same people, reachable on the same details. What changes is what sits behind them: 270+ specialists across seven European cities and Kuala Lumpur, covering every stage from site selection to handover.
Yes. MCA’s commercial, workplace, healthcare, retail and community architecture continues within Hyceon as our heritage practice, led by the same Dublin team. If your relationship with MCA is outside the data centre sector, nothing about how you work with us changes — and we welcome new projects.
Because European data centre delivery increasingly demands one accountable partner across borders and disciplines. Combining MCA’s hyperscale design depth with TTSP HWP’s general-planning, engineering and permitting strength creates exactly that: an integrated group with local knowledge in Europe’s key markets and the capacity for its most complex projects.
Yes. The Dublin studio remains the home of the practice and one of Hyceon’s five European cities. From there the team continues to serve clients across Ireland and the UK, working alongside colleagues in Frankfurt and across the group’s wider European offices.
