Mast Quay, Woolwich - designed by Nigel Upchurch Associates – is an example of good practice, showing a mosaic of different roofs, many of which will use aggregate from the original site in varying depths.

The scheme is a good example of an effective partnership being established between the nature conservation lobby and the developer where the importance of incorporating ecological mitigation works was recognised from the outset, particularly as the site is in an area that is a traditional stronghold for the black redstart.

In addition to working closely with ecologists to provide mitigation for black redstarts, the architects also dealt with in the design other brownfield biodiversity issues.
