What MCA Architects does

MCA Architects is a Dublin-headquartered, privately held architectural practice founded in 1988 as Michael Collins Associates, which has evolved into a pan-European data centre and corporate/ institutional design firm. The company delivers architecture, interior design, master planning, due diligence, conservation and project management services across data centres (representing approximately 70% of turnover), corporate offices, healthcare, hospitality, residential and retail sectors. Its specialised, high-performance data centre practice spans over 7 million square feet of designed capacity, more than 2.6 gigawatts of critical IT load, and 130 hectares of master-planned campuses, serving hyperscalers, colocation operators and cloud providers across Ireland, the UK, Germany, Norway, Spain and other European geographies. The firm is differentiated by deep sustainability credentials - LEED, BREEAM, WELL, Passivhaus, ISO 9001/14001/45001 certifications and its proprietary MCA-2030 Roadmap built on four pillars (Environment, Wellness, Social, Equity) - and by a carbon-conscious retrofit methodology delivering measurable material reuse outcomes (88% at Dockline, 98% at Cumberland Place Phase 1). All revenue is project-based, fee-for-service professional services income, scoped and negotiated per engagement, with multi-year contracts and recurring client relationships across an enterprise roster that includes IBM, Meta, Amazon, Google, Salesforce, Twitter/X, Credit Suisse, Lidl, Travelodge, HSE and Irish government bodies.

In December 2025, MCA merged with TTSP HWP, a German data centre advisory firm, to form a fully integrated European group operating from Dublin, Frankfurt, Stuttgart and Cologne under joint leadership (Alexander Hauser of TTSP HWP as CEO; Brian Murphy as MD of MCA), with more than 240 professionals. The merger was supported by Tikehau Capital's January 2025 acquisition of TTSP HWP through its private equity decarbonisation strategy, providing institutional capital backing. The combined entity is positioned as a pan-European leader in design, engineering and project delivery for large and complex data centres serving hyperscale and global digital-infrastructure clients.

Emerging players

• NBBJ: US-headquartered architecture firm with a strong tech-sector focus, having designed campuses and workplaces for many of the same enterprise clients as MCA (Amazon, Google, etc.). Overlaps with MCA in corporate workplace and tech-occupier practice though less concentrated in pure data centre design.

Broad incumbents

• Arup: Multidisciplinary engineering and design firm with a strong mission-critical facilities and data centre practice across Europe. Competes with MCA for hyperscaler and colocation design mandates and offers overlapping services in master planning, sustainability, and structural/MEP design.
• AECOM: Global design, engineering, and project management firm with a significant data centre and mission-critical facilities practice serving hyperscalers across Europe and globally. Directly comparable to MCA in scope of services (architecture, interiors, master planning) but at vastly larger scale and broader vertical mix.
• Stantec: Global engineering, architecture, and environmental services firm with active data centre practice across North America and Europe. Comparable to MCA's combined MCA + TTSP HWP offering in integrating architecture, engineering, and master planning for digital infrastructure clients.
• Arcadis: Global design and consultancy firm with strong European presence and growing digital infrastructure / data centre capabilities. Comparable in offering integrated design and project management services to enterprise and tech-sector clients across multiple European geographies.
• Gensler: Largest global architecture and design firm with a significant mission-critical / data centre practice and strong European footprint. Competes with MCA for enterprise and hyperscaler workplace, fit-out, and data centre mandates across Ireland, UK, and continental Europe.
• HOK: Global architecture and engineering firm with experience in mission-critical facilities and corporate workplace design. Competes with MCA on enterprise workplace and data centre projects in Europe, with overlapping sustainability expertise.

Direct peers

• Corgan: US-headquartered architecture firm widely regarded as one of the leading specialists in data centre and mission-critical facility design, serving many of the same hyperscaler and colocation clients as MCA. Closest direct peer by specialisation, though focused primarily on North American markets.
• HDR: Global architecture and engineering firm with a dedicated data centre / mission-critical practice serving hyperscalers and colocation operators. Closely comparable to MCA in vertical specialisation, sustainability credentials, and enterprise client base.

Regional players

• Werner Sobek: German-headquartered engineering and architecture firm specialising in sustainable, high-performance building design. Comparable to MCA in combining architecture with sustainability and engineering expertise, and a relevant regional peer given TTSP HWP's German heritage.
