This week we see how architect Peter Wilson copes with a major challenge: he had to build a library in the small Dutch town of Helmond. But the site of the new building is surrounded by 1970s cube houses designed by Dutch architect Piet Blom. Until now they have shaped the face of the city center.So Peter Wilson's design had to harmonize with them. We find out how he rose to the challenge in the next edition of our series The Architect's Eye .
