It’s all change at the top of Sir Euan Anstruther-Gough-Calthorpe’s Calthorpe Estates in Edgbaston.

In September Mark Lee became the new chief executive, replacing Richard Allen who has retired. He was previously chief financial officer.

And City big-hitter Rod Kent is to be the new chairman replacing Sir Charles Nicholson. His background includes Close Brothers Group, Grosvenor Group and Caledonia Investments.

One of Calthorpe Estates major projects currently is the regeneration of the 27 acre site of the old BBC studios at Pebble Mill which is to include a new five-storey dental hospital.

The proposed development is being led by Calthorpe Estates along with Birmingham Community Healthcare NHS Trust, Birmingham and Solihull LIFT and the University of Birmingham which also plans to build a school of dentistry on the site.

The plan dovetails with Calthorpe Estate’s ambitions for the site, with a focus on employment and training to develop a medical, technology and sporting community.

Elsewhere on the estate, in October Morrison’s opened a flagship store at Five Ways and housing development continued at Highfield Gardens and Hagley Road Retirement Village.

Calthorpe Estates continues to pick up accolades on a regular basis for developments on its 1,550 acre estate in Edgbaston, which incorporates one of the UK’s biggest conservation areas.

Sir Euan Anstruther-Gough-Calthorpe’s aim is to ensure that the Calthorpe Estate is quite simply a superb place in which to live and work, just a mile west of the city centre. Sir Euan has worked closely with the management team of Calthorpe Estates and the board of trustees to develop the Edgbaston estate sympathetically, and in a sustainable way.

The Estate has been overseen by 46 year-old Sir Euan’s family – one of the oldest in Birmingham – since 1717. Throughout that time the family refused to allow factories or warehouses to be built within the Estate, so creating a high quality urban village, and leading to the area’s high property values.

It wasn’t until the late 19th century that Edgbaston – then a town in its own right – came under Birmingham administration.

The original family home of the Gough-Calthorpes is now Edgbaston Golf Club.

The Calthorpe Business Alliance was established by Calthorpe Estates to promote the mutual interests of all its business customers to improve the business environment on the estate and make it a better place in which to live and work.

Membership of the Alliance is open to all Calthorpe Estates’ business customers and other organisations such as schools and hospitals.

Calthorpe Estates is investing more than £350 million to give Edgbaston its biggest transformation to date. This includes the award-winning Calthorpe House – 105,000 sq ft of prime office space off Five Ways Island – and the £110 million Edgbaston Galleries development.

Calthorpe Estates holding company, Calthorpe Holdings, made a profit of £1 million in 2010-11, with net assets valued at £5 million.

The Anstruther-Gough-Calthorpe family lives in Elvetham in Hampshire. Sir Euan has property interests in Europe and the Gulf and interests in America.
