Project Experience

Fund restructuring: UK

Giles led the restructuring and reestablishment of a UK-based discretionary closed-end fund vehicle with eight institutional investors in 2015. The original fund structure dated from the mid 2000s and was created to finance the development of a large mixed-use town project in the UK. Giles led the negotiation of new fund terms, reflecting the revised business plan, the retail environment, and the goals of the investors. The fund is still in existence.

Acquisition and management set up: Lyon, France

Giles led the acquisition of 33 buildings on rue de la Republique in Lyon, France from their historic owner in 2012. The portfolio comprises more than 50% of the retail facades of this prime mass-market retail street and their residential and office upper parts totalling 66,000 sqm (710,000 sqft). Giles led the negotiations of both the asset acquisition and the investment structure. He then opened a dedicated local office, staffed it, and created an integrated property and asset management solution for the portfolio. The portfolio was exited in 2018 and the financial returns to the investor exceeded underwriting.

Shopping mall acquisition and turnaround: Stockholm

Giles created a dedicated Luxembourg-based collective investment vehicle with three investors and led the acquisition of a 98,000 sqm (105,000 sqft) regional shopping mall in Stockholm, Sweden in 2014. Giles hired a local team, including a senior asset manager from a competing mall operator, and oversaw the strategic commercial plan for the mall. The vehicle returned double digit total returns, exceeding the original underwriting, during the Giles’ tenure.

Development start-up: Madrid, Spain

Giles developed and put in place a high-end residential development strategy in Madrid on behalf of a joint venture with a Malaysian investor. Giles put in place the processes and controls necessary, hired a local team and oversaw the acquisition of 6 development sites for high end residential in central Madrid.

Office value-add: London, UK

Giles oversaw the acquisition, refurbishment, leasing and subsequent sale of a 7,500 sqm (80,000 sqft) office in London’s mid-town. The project created a profit of c. 50% at the asset level over a period of 3 years.

High street retail fund: France, Italy, Spain

Giles oversaw the fund and asset management of a discretionary closed-end fund of 26 high street retail assets in Europe (115,000 sqm). The fund returned 100bps above its benchmark from inception to 2016, when it largely liquidated.

Retail mall: Helsinki, Finland

Giles acquired 40% of a 20,000 sqm (215,000 sqft) shopping mall in Helsinki from a local operator in 2007. The transaction was structured as a joint venture with significant additional commitments to fund an extension and join the mall to a planned public transportation node.

Retail mall, core investment: Metro Centre, Gateshead, UK

Giles acquired 40% of a 192,000 sqm (2m sqft) shopping mall in Gateshead, near Newcastle in the UK from a local operator in 2006. Giles later acquired the securitised debt obligations of the holding company, further increasing exposure to this dominant shopping centre.
