You might wonder what this building is, just to the north of Westminster Bridge; it is Portcullis House, built recently as offices for MPs. Those strange chimneys you see are part of the "passive" air conditioning system. What it is known for in particular, is the huge cost overrun, creating a palatial interior which cost over £1,000,000 for each MP housed. The public enquiry report into this was never published. Clearly excellent value, eh?
