Stallan-Brand Architects had submitted plans to demolish most of the historic property to retain only the building shell.

But a new application has been lodged seeking permission instead for internal and external alterations to create multi-use/event space and public realm.

Drum Property Group and client Barclays revisited their requirements and approach for the building following consultation with Historic Environment Scotland (HES).

A statement submitted by Stallan-Brand explained: “Our updated proposals are for a bold and exciting adaptation and alteration which turns the building back closer to its original layout and form. We are referring to this approach as a defurbishment, as opposed to a refurbishment.

“The proposal is to defurbish Kingston House, by stripping it back to its bare primary structure (close to its original form) and making bold new interventions through creating central voids through the upper floorplates, a new large rooflight above the voids and an adaptable fully openable ground floor facade.

“The purpose of this is to achieve Barclays’ original brief as a covered public space, event space and important gateway structure (in lieu of Grade A office space, which Kingston House cannot provide)…but without the need to make a substantial partial demolition of Kingston House.”

The statement added: “The adaptation and alteration of Kingston House is essential to delivering these significant benefits to economic growth.

“Barclays and their masterplanner’s aspirations saw the gateway provided by Kingston House as being central to their concept and their interest in the location.”

Meanwhile Stallan-Brand has also lodged plans for an Early Years Centre as part of the overall Barclays masterplan.

The nursery would be situated on the westernmost boundary of the financial services hub.
