O Walkie-Talkie (20 Fenchurch St) é apenas o 13º edifício mais alto de Londres, a 160m de altura, mas ele tem uma galeria de visualização gratuita (altura 155m):
The famous enlarged glass dome of 20 Fenchurch Street is dedicated to three storeys of exquisitely landscaped public gardens and London’s most exclusive social spaces, including observation decks and an open air terrace.

Esteja avisado que o 'jardim do céu' não encontrou favor universal, então não deixe suas expectativas muito altas:
The building was crowned with a Sky Garden, a babylonian jungle in the clouds that would be the pride of the Square Mile, framed as not just a place for bankers to drink, but a public space accessible to all. The reality is anything but. If you book three days in advance, or reserve a table at one of the overpriced dining concepts, you can go through airport-style security and be treated to a meagre pair of rockeries, in a space designed with all the finesse of a departure lounge. A hefty cage of steelwork wraps around in all directions, obscuring much of the view, while the restaurants rise up in a boxy stack of glass portable cabins. The more you pay, the worse the view gets: at the very top of the gourmet ziggurat, you’re as far from the windows as possible.
Copa Carbuncle: Walkie Talkie ganha prêmio de pior edifício do ano , The Guardian, 2 de setembro de 2015
O quarto edifício mais alto de Londres (225m) é o Cheesegrater (Edifício Leadenhall) . Normalmente não é aberto ao público, mas é aberto para um fim de semana por ano durante o Open House London .
Open House was started in 1992 as a small, not-for-profit organisation to promote public awareness and appreciation of the capital's building design and architecture. The intention was to open up London's splendid buildings to the general public who don't otherwise have access. We saw this as a way of helping the wider community to become more knowledgeable, engage in dialogue and make informed judgements on architecture.
The dates for Open House London in 2016 are 17 & 18 September
Você precisará de ingressos antecipados - verifique o site da Open House mais perto do horário (em anos passados, as informações foram disponibilizadas em agosto).

Eu acredito que o Gherkin (30 St Mary Axe, 180m) também abre suas portas para o fim de semana da Open House.
