With regard to the article on Greenwich Millennium Village, Powerwall Systems Ltd did not design the building with the problem.

Powerwall Systems was involved in other buildings at Greenwich but had no input whatsoever into the design or erection of this particular building.

The only involvement of Powerwall in this building was to supply the Honeycomb panels and external finishes, which are not in question in this case. I also wish to point out that Powerwall no longer supplies parts of its system; we only supply the full Powerwall system to Powerwall's specific design.

We are very concerned this article may have damaged our reputation. We trust this letter has addressed all the issues concerned.
