Grand Designs Show Summary

Grand Designs is a Channel 4 TV series covering unusual architectural house-building projects, presented by Kevin McCloud.

The properties featured in the series vary wildly from homes underground to converted water towers, with the only common factor being that they're all rather unusual or extravagant in some way.
