The new owners of the Castle Mona Hotel have confirmed they have bought another landmark site on Douglas seafront.

Tevir Group announced earlier this month that it has bought the Castle Mona as well as the former Zurich headquarters on Athol Street.

And now it has confirmed that it has acquired the buildings and land comprising the Villiers site.

The purchase includes Villiers House (formerly RBSI House), Clarendon House and land made up of a development plot and eyesore area known rather grandly and with some irony as the ’Town Square’.

A comprehensive clean-up of the Town Square began on Monday following talks with the Manx government and Douglas Council.

Tevir says island-based architects and urban designers are being engaged for the first phase of a project that will ultimately lead to a ’contemporary’ public space being developed.

Long-term plans for the development plot on the site are currently being considered. But Tevir is staying tight-lipped over what those plans might be - or indeed what proposals it has in mind for the former Castle Mona Hotel.

’The purchase of the Villiers site reflects the Tevir Group’s ambition to progress significant development projects in the Isle of Man, which will ultimately benefit the local business community, residents and the broader economy in the island,’ it said in a statement.

It says the vacant Villiers House will be subject to an extensive refurbishment.

Meanwhile, Clarendon House is fully tenanted and the group says it will work with all tenants there to achieve a smooth handover and improve the services provided.

The former Zurich headquarters on Athol Street, which was acquired for £4.3m, is undergoing extensive building works and refurbishment to create a ’premium multi-tenant office space’, says Tevir.

Work has already begun on this site and is expected to be completed during the summer of next year.

Estate agents Black Grace Cowley is already in advanced negotiations with a number of parties and the first tenants are expected to move in shortly after completion.

Work is also under way at the former Castle Mona Hotel on Central Promenade in Douglas to secure the site and to prevent further deterioration to the historic building which has lain empty since 2006.

The Castle Mona was sold at auction for £1.21m in May but the identity of the owners was kept firmly under wraps for months - until the Examiner revealed their identity.

The new owners have not said what they intend to do with the historic building.

Tevir Group was incorporated in the island at the end of August, with a registered address at Analyst House on Peel Road, Douglas. KJ Holdings is named as the company carrying on the business, in the application for registration.

Companies Registry names KJ Holdings’ directors as Keith Jones and accountant Ciaran Colm Doherty.

Mr Jones and Mr Doherty are also directors of Kero Holdings Ltd, which is a director and shareholder of Flintshire-based Kero Ltd. The name of Kero Holdings was changed to Tevir Ventures Ltd in August.

Keith Jones, aged 75, is named as a ’person with significant control’ - ie beneficial owner - of the UK company.
