Senior Team

Pat founded 3RE in 2020 after selling Green REIT plc, Ireland’s first real estate investment trust which he cofounded in 2013, to Henderson Park in November 2019 for €1.6bn enterprise value / €1.3bn equity value.

He originally joined Green Property in January 2009 as Managing Director of the various Green Property businesses, initiating the development of a multibillion real estate workout business on behalf of banks and private equity firms post GFC. He was formerly European Board Director of CBRE and on the Advisory Board of the European Public Real Estate Association (‘EPRA’) from September 2018. In 2024 3RE formed a joint venture with Aermont to invest in the London office cycle with a ‘brown to green’ focus in a dislocated opportunity set.

Mike leads development delivery at 3RE, bringing over 35 years of hands-on experience building, refurbishing and repositioning large-scale office assets across London. Before 3RE, he co-founded Viridian Property in 2017.

Mike’s career includes significant time at Green Property, where he established a UK office development business and managed distressed NPLs and Bank Workouts. He also worked at Miller Developments, building a £450m  UK and European investment platform. Earlier, Mike spent a decade at St Quintin Chartered Surveyors. His experience includes managing and selling over £1bn of commercial real estate for various lenders, as well as building, refurbishing, or repositioning over 2 million square feet of office space in the UK. At 3RE, Mike focuses on repositioning, asset management, and real estate investment, particularly in large office properties.

Michelle brings together the financial, operational, sustainability and asset management workstreams; ensuring the 3RE business functions as a single, integrated whole rather than a collection of separate disciplines. Previously, she worked alongside Pat Gunne at Green REIT Plc in managing the company’s €1.6 bn portfolio.

Michelle also served as an external advisor to Ireland’s largest residential REIT, leading investor relations, sustainability and corporate development initiatives. She was formerly a committee member of the European Public Real Estate Association (‘EPRA’) Investor Relations Committee. Michelle holds an Executive MBA from Trinity College Dublin, a Masters in Real Estate, and a BSc in Finance. As a qualified Chartered Surveyor (RICS), Michelle brings expertise in both commercial and residential real estate to 3RE, with a particular focus on integrating sustainability practices into operations and investment strategies.

Tom is a qualified Building Surveyor with particular expertise in complex office refurbishment, contract procurement and construction management.

Having worked alongside Mike Tapp throughout his career, he brings a complementary and proven skillset across technical due diligence, contractor management and project delivery. He began his career at St Quintin, where he built and led a Fund Monitoring team. Since 2006, Tom has managed all UK developments at Green Property, specialising in complex repositioning projects. In 2017, he co-founded Viridian Property with Mike Tapp, further expanding his industry involvement.

Caroline brings over two decades of specialised expertise in portfolio and asset management within the real estate sector. Her career includes senior positions at leading property firms, including previous roles at Green Property and CBRE, before joining Goldman Sachs Asset Management as Executive Director. At Goldman Sachs, she oversaw the asset management of the company’s Irish real estate portfolio, notably leading the transformation of Blanchardstown Shopping Centre and managing complex equity and debt transactions across diverse sectors including Office, PRS, and Hotels. As a qualified Chartered Surveyor, Caroline is recognised for her strategic approach to value creation and her ability to reshape investment strategies to optimise portfolio performance.

Stephen is Finance and Investment Manager at 3RE, with responsibility for investment analysis, capital structuring, and financial oversight across the firm’s transactions and advisory activities. His role spans underwriting, capital planning, and the financial governance framework that supports the execution of investment strategies.

Prior to joining 3RE, Stephen was Manager of Investor Relations and Capital Markets at Irish Residential Properties REIT plc (IRES REIT), where he worked closely with senior management on a range of strategically significant initiatives, including the internalisation of the REIT’s management company, capital allocation analysis, shareholder engagement, and long-term strategic planning. This role provided him with direct exposure to public market investors, capital raising considerations, governance frameworks, and the investment decision-making processes of a listed real estate platform.

At 3RE, Stephen applies this capital markets and institutional investor perspective to the evaluation and execution of opportunities, as well as to the firm’s engagement with capital partners – ensuring financial discipline, analytical rigour, and alignment between strategy and capital.

Stephen holds a Bachelor of Commerce from University College Dublin and has completed Level I of the CFA Program.

Stephen built his career at CBRE, the global leader in property advisory services, where he progressed through multiple senior positions before serving as UK Chairman until his retirement in 2019. Since that time he has been Chairman of Workspace plc, London’s leading provider of flexible offices. He maintains several strategic advisory positions, including serving on the board of the Australian Super/BL joint venture responsible for the Canada Water development. Most recently, in May 2024, Stephen was appointed Chairman of the King’s Cross Central Limited Partnership.
