10 Downing Street
Logistics Guide

You cannot enter Downing Street itself as it is a high-security government residence. However, the famous black door is visible from the Whitehall security gates. The viewing area on Whitehall is 100% accessible, featuring wide, smooth pavements ($5\text{Hz}$ vibration) and no steps. It is a very easy 'roll-by' landmark.

The nearest high-quality PRM restrooms are in the 'Churchill War Rooms' (entry fee required) or the public toilets at Westminster Pier. For a free option, the 'Lord Moon of the Mall' pub at the end of Whitehall has excellent accessible facilities.

The best drop-off is 'Whitehall / Horse Guards Avenue' ($51.503800, -0.126100$). This is a very wide part of the street with a long dropped curb, allowing a taxi to deploy a ramp safely before you roll the $50\text{ meters}$ to the gates.

It has a 'monumental and high-security' sensory profile. Acoustically, it is noisy due to traffic ($70\text{dB}$) and occasional protests. Visually, it is dominated by grey stone and black ironwork. Physically, it is very stable ($5\text{Hz}$). There is a heavy police presence which can be intimidating for some.

Yes, Whitehall is a major tourist artery. However, the pavement is over $6\text{ meters}$ wide, so even with crowds, there is plenty of room to maneuver a large power-chair.

The police are usually very accommodating. You can say: 'Could I please move closer to the gate for a photo from my chair?' They will usually ensure you have a clear spot.
