London’s Architecture

Following the Great Fire of London in 1666 which destroyed most of the buildings, the city was rebuilt. Christopher Wren was one of the main architects involved and during this time he designed Kensington Palace and St Paul’s Cathedral, one of the finest examples of British Baroque architecture.

Later, the Georgians built the iconic red brick, terraced buildings seen in central London today, such as Grosvenor Square. In the Regency period that followed, buildings were designed with the white stucco facades that we see in Belgravia. John Nash was a leading architect and was responsible for Regent’s Street and Regent’s Park.

The Victorian era, following the Industrial Revolution, saw the revival of elaborate architecture, typified by St Pancras Station and the Houses of Parliament. The country’s new prosperity was reflected in the growth of homes for the expanding middle class, as well as homes for the growing numbers of factory workers.

The Edwardians continued to build homes in London – these were often larger than their Victorian forerunners and many were in a terraced style. Art Deco houses followed in the 1920 and 30s, including many apartment blocks and Southgate Underground Station. In World War II, London was badly bombed and there was a need for rapid rebuilding which resulted in the construction of many high-rise flats.

In the 21st century, the city is a melting pot of architecture. Contemporary developments include high-rise luxury apartment blocks, and the skyline boasts new London architecture such as The Gherkin and The Shard.

Development of London

The London Plan 2021, the master planning strategy for the next 20-25 years, prioritises the need for house building.

The population is expected to grow by 70,000 each year to reach 10.8 million in 2041, underlining the urgency for building huge numbers of homes along with creating employment space. Mayor of London, Sadiq Khan, wants to see tens of thousands of new homes built every year.

The London Plan aims to rebalance development in a particular order to see more affordable housing to both buy and rent, and a greener, safer city. Each London borough has housing targets with sustainable growth a guiding principle.

The Plan also wants to create well-paid jobs and improve transport links, with walking and cycling to become mainstream options in a city with cleaner air due to low emission zones. The Plan identifies space for over 52,000 new homes per year and a target for 50% to be genuinely affordable.

Schemes that deliver 35% affordable housing are to be fast-tracked and new buildings must be built to low carbon standards.

Why Hire an Architect?

The best architecture firms hold an extensive knowledge that can add value to all stages of a scheme. As a result of this, hiring architects in London from one of the many architecture firms with a proven track record may well save you money in the long term.

An architect is trained in building design and construction, enabling them to calculate the best use of space or suggest the most energy-efficient way to heat a house. Their knowledge of maintenance and running costs is also helpful.

An architecture practice can be useful for just the initial stages of your scheme, for instance preparing drawings and obtaining planning permission, or they can be involved for its entirety, master planning project management duties.

Total involvement can include creating technical drawings for builders to quote on, selecting the builder to use and dealing with contracts, monitoring the build, and keeping tabs on costs. Paying attention to detail is their stock in trade!

Architects will be used to dealing with the relevant local planning authority and will be aware of its environmental aims and policies on reuse of old or historic buildings and low carbon materials.

The best London architects can ensure that your scheme satisfies the local authority’s requirements for enhancing the development area through biodiversity net gain (BGN), which may involve installing bird or bat boxes or incorporating special habitats into the scheme.

All architects in the United Kingdom must be registered with the Architects’ Registration Board, and most are members of the Royal Institute of British Architects.
