The Horton Street tech corridor is getting another major boost with the construction of a $3-million office building that will wrap around the London Roundhouse.

Creative Property Developments has begun construction of the 1,600-square-metre building at 240 Waterloo St. that will serve as a consolidated headquarters for Royal LePage Triland Realty.

It’s the second phase of a project that began in 2015 when Creative Property renovated the historic railway building called the London Roundhouse.

It became the new home for Ellipsis Digital, a digital agency.

Creative Property co-owner Slavko Prtenjaca said he’s working on the third phase of the Roundhouse project, a residential highrise tower.

The company is negotiating with city planning officials over the height of the proposed tower, he said.

Creative Property is trying to secure zoning to permit construction of a taller building.

“They are telling us that 16-storeys is no problem. We’re shooting for 25 storeys,” Prtenjaca said.

Ellipsis is one of a cluster of tech companies that have moved into area during the last few years.

Another tech company will share the new office building with Royal LePage but Creative Property isn’t disclosing the second tenant’s name.

A building that formerly housed the headquarters of Southside Construction has been demolished at the site.

The new building is being constructed on that footprint. It will be connected to the Roundhouse and extended around the rear of the property to create a semi-circle.

Creative Property has extensive land holdings in the immediate area and Prtenjaca said other projects are in the works.

Roger Caranci, a Royal LePage Triland sales rep and a consultant for Creative Property, said the city’s decision to rebuild Horton Street about five years ago and install a landscaped boulevard is paying off with substantial redevelopment of the area.

“The money the city spent has been a real boon to that area,” said Caranci, a former city councillor.

Construction of the new office building is scheduled for completion in October.
