This weekend it's that time of year when it's Open House again and a variety of buildings across the capital open to the public.
Amongst the usual suspects are the Gherkin and Lloyds of London, both of which will have heavy queues, but there's a good range of mid-rise buildings that will also be open and these should be easy to visit without having to wait for hours to get in.
10 Brock Street, the latest office tower at Regent's Place next to Euston Tower will be open. Designed by Wilkinson Eyre and only recently completed it's within easy reach of Tottenham Court Road and should have great views of the West End. It's open on both Saturday and Sunday from 10am to 5pm.
Make's radical reworking of 55 Baker Street, an old 1950s office building that got a brand new and very impressive entrance area and atrium is open on both Saturday and Sunday from 10am to 6pm. Unfortunately only the ground floor and atria are going to be open to visitors, but these are the best parts of the scheme.
In the City of London, 30 Crown Place will be having hourly tours from 10am to 5pm on Saturday and Sunday. Amongst the floors that will be open are the top three which each have their own terrace.
Fans of Richard Rogers will be able to visit both 88 Wood Street and the Lloyds Register of Shipping, two of his famous trio of office buildings, the third of which is Lloyds. They are both open on Saturday only from 10am onwards.
Tower 42 will be open on Saturday from 10am until 3pm. Heavy queues are expected there, although they should be less than the Gherkin and Lloyds. Those who care for visiting anyway should be aware the top of the tower, level 42, which will be open to visitors, will also be open only a couple of hours later to drinkers if they care to book in advance.
