STB - Roxby House - Sidcup - 038

Cubica Capital has secured a £6.8m loan from Secure Trust Bank Real Estate Finance to refinance Roxby House, a recently converted office block in Sidcup.

The five-year residential property investment facility funds the completed redevelopment of the five-storey building, originally designed by prominent post-war architect Owen Luder.

Following an extensive refurbishment completed in June 2026, Roxby House now comprises 34 contemporary one- and two-bedroom units, which are being rented out to young professionals. Located near Sidcup station, the property offers strong transport links into central London, with London Bridge accessible in under 40 minutes.

Structured at 70% loan-to-value, the transaction builds on a five-year relationship between Cubica Capital and STB. The facility is one of nine live deals between the two parties, with a combined value approaching £100m.

Alasdair Bowers, relationship manager at STB, headed up the deal, working closely with Ariel Mozes, director at Cubica Capital, to achieve drawdown in just over three months.

"We've worked with Alasdair and the team for many years," said Ariel Mozes, director at Cubica Capital. "Throughout the process, Alasdair was just a phone call away in the event of any potential obstacles and ensured the transaction was as seamless as possible.

"Roxby House has been thoughtfully transformed into a vibrant residential community. The redevelopment delivers modern residential accommodation while carefully retaining the building's architectural character. It is a welcome addition to Cubica Capital's growing residential portfolio."

"Working with Ariel and Cubica is always an enjoyable experience," said Alasdair Bowers, relationship manager at STB. "It's incredibly rewarding to see exciting developments like Roxby House come to life, especially considering the early demand for tenancies."
