Plans have been submitted to alter an iconic Swindon landmark so that it will be suitable for new tenants.

Knight Frank has set out proposals on behalf of AEW UK Investment Management LLP to partially demolish the interior of the Grade II* Spectrum Building on Mead Way and prepare it for future occupants.

If Swindon Borough Council approves the two applications, the building would be reverted to how it was before 2010, after Renault left the site but before Kidz About, The Golfing Hole, and Cooper Tyres occupied the space.

The building fabric associated with the old soft play area would be removed, a non-original internal warehouse office facility would be demolished, an external access walkway would be replaced, and other minor maintenance work would be carried out.

Knight Frank argues that the work will not harm the historic significance of the building.

A spokesperson said: “The applicant’s overarching objective is to secure the occupation of The Spectrum Building through the imminent open-marketing of the site to prospective commercial occupiers.

“To enhance the prospects of achieving this objective, they wish to reverse building works specifically relating to the previous children’s soft-play facility, alongside a number of other measures to increase the attractiveness of the site to the widest possible range of potential commercial tenants.

“It is [AEW UK]’s full intent to secure the most viable use of The Spectrum Building and to ensure its long-term viability as a functioning economic asset."

Major maintenance and roof repairs are currently in progress on the yellow West Swindon landmark.

The full proposals can be viewed on the Swindon Borough Council website using references S/24/0294 and S/24/0295.

The thrust of the argument is that, since the Spectrum building was intended to function as a warehouse with ancillary office and amenity facilities in visually spectacular architecture, the site’s optimal use is one that is consistent with that original aim.

So, Knight Frank suggests, warehousing and other commercial uses would require the least alterations to the building’s fabric, once additions made by Kidz About are removed.

The spokesperson added: “The Spectrum Building was designed and intended to serve a functional purpose, and not merely act as a static ornament, with its current vacancy serving to detract from its significance.

“The proposed alterations, primarily comprising the strip-out of recent additions to the building, are solely intended to improve the attractiveness of the site to the widest possible range of industrial, warehousing and commercial tenants and increases the likelihood of the building being put back into active use.”
