Hyceon was created by bringing together two practices that grew up with the European data centre industry itself.
In Frankfurt, TTSP HWP was established in 1990 and grew into Germany’s leading data centre general planner, entering the sector in 2007, dedicating itself exclusively to data centres, and building an interface-free, full-service model spanning architecture, engineering, permitting, sustainability and project management through its specialist companies. Its work includes milestones such as the Citigroup data centre in Frankfurt — LEED Platinum certified, at the time unique worldwide for a data centre — and campuses across Germany’s data centre heartland.
In Dublin, MCA Architects, founded in 1988, evolved from one of Ireland’s most established architectural practices into a trusted design partner for the world’s largest technology companies. Over more than fifteen years of hyperscale and colocation experience, the practice has designed more than seven million square feet of data centres, delivered 2.6 gigawatts of critical IT load and master planned 130 hectares of campuses across Ireland, the UK, the Nordics, Germany, France and Spain.

A Shared Ecosystem
We are one team. Across national and disciplinary boundaries, architects, engineers and project managers work together in a shared ecosystem built on trust, respect and a shared vision.
How we work
One partner, every stage of delivery – from the first site visit to the day the facility goes live.
EN 50600, Uptime Institute Tier and ASHRAE anchored design, to targeted PUE benchmarks of 1.2 or lower – commitments procurement teams can verify.
Architecture, engineering, permitting, sustainability and project management under one roof – interfaces engineered within the team, not negotiated between consultants.
Energy, water and carbon performance engineered in from the first master plan – our Blue Future vision in practice.
Hundreds of permits secured; teams working in the local language and legal instruments of every market we serve.
Eight cities.
Every European market.
From offices in seven European cities and Kuala Lumpur we deliver across Ireland, the UK, Germany and wider Europe — including the Nordics, Switzerland, France, Poland, Italy, Spain and Portugal. Teams work in the local language and regulatory instruments of each market, and run to one group standard.
Why Hyceon?
Our symbol is six circles arranged as a lowercase “h” — one for each principle that underpins world-class data centre design: Reliability, Scalability, Efficiency, Security, Flexibility and Sustainability. Set against a larger blue circle, it carries our commitment to the Blue Future: resilient, high-performance digital infrastructure that treads more lightly on the planet that hosts it.

Data centres — primarily and increasingly exclusively. Six integrated services cover the full lifecycle: feasibility and due diligence, master planning and permitting, architecture and design, engineering design, sustainability and ESG, and project management, for hyperscale, colocation, edge and enterprise clients and the investors behind them. Strategic non-data-centre architecture continues as part of the practice’s heritage work.
The group carries 70+ combined years of practice heritage, 10+ gigawatts of data centre projects assessed, designed and delivered, hundreds of permits secured across European jurisdictions, and long-term relationships with the world’s largest technology companies and data centre operators.
Because clients asked for it, in effect: European data centre delivery increasingly demands one accountable partner across borders and disciplines. Combining Dublin’s hyperscale design depth with Frankfurt’s general-planning and permitting model creates exactly that — integrated capability with local knowledge in Europe’s key markets.
