LANSDOWNE HOUSE PUBLIC EXHIBITION LANSDOWNE HOUSE TODAY LANSDOWNE HOUSE

The modern-day Lansdowne House was completed in 1988, but has a number of significant issues, including:

• Inefficient layout with a large atrium, numerous cores and limited floor to ceiling heights which results in an inflexible building that provides poor-qualityEXISTING office accommodationPLAN in a landmark location in Mayfair • Poor sustainability credentials – at a time when buildings contribute over 50% of the emissions which negatively affect air quality in central London • A defensive design with small openings creating a hostile building which negatively contributes to the surrounding area • Poor quality retail and public realm around the site – particularly on Lansdowne Row and narrow pavements on all frontages

Lansdowne House typical plan

The existing 9 storey building is served by 6 cores surrounding a central atrium. The typical floorplate has a warren-like quality of spaces. The building is largely cellularised as a result. Existing Site

LANSDOWNE HOUSE PUBLIC EXHIBITION A BUILDING FIT FOR THE FUTURE LANSDOWNE HOUSE

Alberti wrote:

"Beauty is the harmony and concord of all parts achieved in such a manner that nothing could be added or taken away or altered except for the worse."

The new proposals for Lansdowne House take inspiration from the way in which the structure is celebrated and not hidden away. It is an architecture of permanence and inherent flexibility, capable of responding to future unanticipated challenges.

Modern techniques of building create longlasting architecture.

A proposed 21st Century building has top lit circulation spaces, stairs are visible and celebrated to encourage their use. This central promenade is generous and adaptable, allowing its reimagining in future use.

LANSDOWNE HOUSE PUBLIC EXHIBITION DESIGN LANSDOWNE HOUSE

The Site presents a great opportunity to create a civic presence on Berkeley Square, one of the most important and enjoyed .

Inspired by the original Lansdowne House’s (1768) garden and pavilion relationship, the new building seeks to create a new palazzo on the square, framing the southern end of Berkeley Square with a design which respects and responds to its local context and key views. Mayfor Oriel and arcade We are seeking to create a ‘piano nobile’ (Italian for “noble floor”) a composition technique borrowed from renaissance architecture and prevalent throughout Mayfair. This variation of storey heights going up the building is in a similar fashion to the Georgian and Victorian facades on Berkeley Square.

The proposal is for a high-performance modern building, which has at the heart of its design, classical principles inherent to Mayfair’s distinctive character. The new design will have a formal composition.

Opportunities arise from the deep façade to create loggias: internal Formal composition balconies that further enrich the façade’s depth and composition which will allow occupants to step outside on all levels of the building.

Unusually for a modern building, the masonry exterior supports the building, creating a rich and deep external appearance.

The columns are sculpted to be structurally efficient allowing space between for high performance Oriel windows, referencing Mayfair’s curved glass shopfronts.

The building would curve gently to embrace the square, the corners are curved to soften the building.

The building facing the Square will have a symmetrical arrangement rising higher centrally, in keeping with a classical façade arrangement.
