Open-City, the organisation behind the immensely popular Open House London weekend, has just announced a new programme of architectural walks around the city between now and May.

There are seven to choose from. All sound mouth watering if you enjoy exploring architecture.

South London Regeneration – Borough, Bermondsey and Bankside, from the towering Shard to the area’s many experiments with housing developments.

Hidden West End – The architecturally interesting buildings, old and new, that you might not have noticed in this most familiar part of town.

East End Transformation – Discover how the development of Canary Wharf, the upcoming Olympics and other initiatives have radically changed the built environment of east London.

The Square Mile – Of all the areas in London, its most ancient offers the greatest variety of architectural styles, from Roman walls to towering glass edifices.

Boat Tour: Architecture of the Thames – Take a leisurely boat trip, first upriver to Battersea, then downriver to Canary Wharf , while an expert guide discusses the history and architecture of the river’s most important buildings.

Photography Tour: The Changing Face of London – Another tour of the City, but this time with camera in hand and a specialist in architectural photography to guide your focus.

Evening Residence Tour: The Gap House – Take a snoop around Bayswater’s unusual Gap House, a narrow residence squeeze between traditional terrace houses.

Walk times, dates and costs vary, so check each individual page for further details and other booking information.
