ISG is working on an extensive extension and refurbishment of the Wellington House building in Wimbledon to create new office space for client Threadneedle Pensions Ltd.

Work to date has included demolition of existing cores and facades and an extension to the rear of the building, as well as the development of an additional floor, new exterior, and central cores.

The Wellington House project is due for completion in late spring 2019 so visitors will be able to get a sneak preview of the rejuvenated building, prior to the final works before handover to the client.


The building has two existing tenants within the building, one a restaurant that is open 12 hours a day 7 days a week, the other an estate agent also open 12 hours per day 6 days per week.

There are two office buildings to the side and rear of the project as well as a residential block of apartments on the SE elevation.

There is a private school directly opposite the site with students ranging from 4 – 18 years old. Due to this there is a road closure restriction only between 9am to 14.45pm daily and all deliveries need to be in place during that time.

With all the above mentioned constraints and the enforcement of a section 61 in place with the local council which restricts the times we can make any noise the demolition and construction of the new building has had to be precisely planned and actioned with accuracy and precision so that no complaints were received or filed into the Considerate contractors scheme (CCS).

In the period we have had two planned visits with the CCS at which we are assessed on our consideration to the neighbours, tenants and general public. The first visit we received a score of 40/50 which is very good, the second visit we received a score of 42/50 which was a great achievement for the whole team.

On arrival, all visitors will receive an induction before a presentation on the history of the project. Visitors will then be provided with PPE and escorted around the project by a member of the construction team where they can see first-hand the works that are taking place behind the scenes.
