Property portfolio

Along with properties dedicated to healthcare, we own a portfolio of residential, student, commercial and agricultural properties.

Ronald McDonald House at Evelina London

A large and diverse portfolio

Our property portfolio is valued at £400 million. Most of our properties are based in the London boroughs of Lambeth and Southwark, but we also own significant agricultural holdings across the UK.

Around 62% of the value of our portfolio sits in properties that are over 50 years old. Along with making our endowment more resilient, long-term assets like these bring unique opportunities to help improve places over many generations. 

Our portfolio is made up of residential and student accommodation, and properties for commercial, agricultural, healthcare uses as well as larger mixed-use developments. They are managed by a mix of in-house experts and specialists on our behalf, to ensure that we maximise financial returns and that we handle them consistently with our mission and values. 

Residential and student accommodation

Student accommodation accounts for around a quarter of the total value of our portfolio. The health and wellbeing of our tenant students is paramount, so we are committed to making our properties a sustainable and inclusive environment for students to live in. 

Our residential properties have been accumulated over many years. We are redeveloping our existing residential blocks to offer higher quality homes and affordable housing.  

An example of our student accommodation is our two residences for postgraduate students at King’s College London, which are located at London Bridge.

Orchard Lisle & Iris Brook Houses

These hold around 287 rooms; a mix of flats and studio units. Student accommodation is the main emitter of carbon in our portfolio, so we have switched to a green energy supplier and replaced all lights in communal areas with LED sensor lights to help reduce the environmental impact.

Fresh Student Living Limited look after our student portfolio and our residential properties are handled by Allsop Letting and Management Limited.

Around a third of the total value of our portfolio is made up of commercial office properties located in London. Our commercial portfolio has been built up over many years and we are currently exploring redevelopment opportunities at two key central London sites. Examples of more recent acquisitions include the Miller Pub in London Bridge and office buildings like Becket House in Westminster. 

Becket House

As part of our long-term property strategy, in 2015 we bought the head lease of Becket House, a 146,000 sq ft office building opposite St Thomas’ Hospital. We already own the freehold of this prime site and 3.88 acres of neighbouring land. This purchase represents a solid investment and a strategic acquisition given its proximity to our other land holdings and to St Thomas’ Hospital.

Our commercial investment property is managed by Lambert Smith Hampton.


Over the years, we have accumulated significant agricultural holdings across the UK. Some of these have potential for future development. We are exploring alternative uses for some of this land, including making space for new homes. We’re working with our specialist advisors to ensure that future uses promote our mission of health and wellbeing, and create sustainable communities and benefits for generations to come. This is the case for land we own in Cambridge.


Affordable housing, sustainability and improved biodiversity are all at the heart of a scheme which has been designed for development on land we own in Cambridge. Allotments, an orchard, pathways for cyclists and walkers and electric car charging points will help to create a sustainable, green community and improve biodiversity on the site.

Our agricultural portfolio is managed by Savills.

Healthcare facilities

We use some of our properties to house facilities for healthcare and related activities, and offices for clinical and non-clinical staff. Many of these are in close proximity to sites of Guy’s and St Thomas’ NHS Foundation Trust. These properties achieve healthcare benefits which contribute directly to our charitable objectives. Examples of properties we use for healthcare purposes include Ronald McDonald House and Nuffield House

Ronald McDonald House, Evelina London

Ronald McDonald Houses provide free ‘home away from home’ accommodation to families with children in hospitals across the UK. We helped relocate the long-standing Ronald McDonald House closer to Evelina London Children’s Hospital and St Thomas’ neonatal unit. Working with partners, we identified a new site, bought leases on the land and provided it free of charge to Ronald McDonald House Charities to build and run the new facility. The new House has 59 family rooms and a range of indoor and outdoor communal facilities for families with children in hospital.

Mixed developments

Royal Street

In 2020, we contracted with Stanhope PLC and The Baupost Group to progress the redevelopment of Royal Street, a five-acre mixed-use site opposite St Thomas’ Hospital. Working with local stakeholders, we have been formulating plans to deliver a world-class scheme with health and wellbeing at its heart.

This major new development site for London will create a significant med-tech hub dedicated to using technology to progress medical developments, as well as residential property and office space.
