On 3 and 4 July workers in the capital will be given the opportunity to use St James's Park as their office.
The campaign will see the "Outdoor Office" created in order to encourage both Londoners and visitors to the city to make more of the great outdoor spaces that London has to offer.
The outdoor office will come complete with free Wi-Fi, reception desk - with receptionist - a boardroom, a brainstorm room, 12 hotdesk areas and even a water cooler.
The Outdoor Office will be situated overlooking the lake just off Birdcage Walk and Londoners can reserve areas for up to 2 hours between the hours of 9.30am and 6pm with a receptionist on hand to co-ordinate the bookings.
