Architectural trends play a key role in shaping both the interiors and exteriors of residential houses and flats. The main tendencies for 2025 focus on sustainability, biophilic design, minimalism, and functionality with the efficient use of space. In the UK, particularly in major cities, the ongoing trend of converting 19th- and 20th-century industrial buildings into residential apartment blocks, as well as transforming Edwardian and Victorian mansions into more functional, amenity-rich private homes, remains highly popular. Let’s take a closer look at these key directions and how they are being realised.

Sustainability and care for the environment

Architectural studios are increasingly incorporating the principles of sustainable construction, including the use of environmentally friendly materials — particularly those with high thermal insulation properties that help reduce heating costs — and energy-saving technologies such as solar panels.

Designers and architects are also striving to preserve green spaces as much as possible when planning for biodiversity. This approach is even being implemented in multi-storey apartment complexes, for example, through the creation of green roofs and lounge areas within internal gardens. Biophilic design further enhances residents’ well-being by improving their psycho-emotional state, creating a more comfortable and healthier living environment, oxygenating the air, and filtering pollutants.

Notable examples of sustainably designed buildings include Fulham Riverside, Neo Bankside on the South Bank, and Battersea Power Station.

Conversion and regeneration of old buildings

Textile factories, breweries, and 19th- and 20th-century dock buildings, of which there are many in London, are increasingly being transformed into residential complexes featuring luxury flats and studios with a functional aesthetic. Such buildings often retain their distinctive colourful brick facades, high arched windows, and massive wooden beams — elements that skilled architects can adapt to create atmospheric homes with Art Deco influences.

This transformation not only preserves historical heritage but also maximises the use of space in densely built-up cities, where land availability is a common challenge. Examples of realisations:

• The 19th century The Chocolate Factory in North London has been converted into stylish lofts, high-ceilinged flats, and exhibition spaces, this former factory retains much of its original layout, as well as its colourful brick facades and large windows, which provide ample natural light;
• St Pancras Chambers, a Gothic-style hotel and station built in 1873, has been converted into exclusive apartments, with its arched windows and decorative features, such as stained glass and mosaics, carefully preserved;
• The former Marine Wharf warehouses by the Thames, constructed in the early 20th century, have been transformed into a modern residential complex featuring numerous flats and communal living spaces.

Another popular option is the renovation of old properties from Victorian/Edwardian times (1837-1910). Preserving historical heritage and adapting it to modern, comfortable conditions are challenges for the architect team. 

Functionality and Maximum Space Utilisation

In large cities, where high building density and rising property prices pose significant challenges, architects are increasingly finding innovative ways to maximise space. One solution is the design of micro-apartments, typically ranging 25-35 square metres, where built-in furniture, foldable beds, and multifunctional layouts ensure that every metre is utilised efficiently. A notable example in London is the Pocket Living complex.

Another popular approach is vertical development and the addition of extra floors. Mansard apartments are becoming increasingly common in London and other major cities. Architects also offer various solutions for expanding living spaces. For example, the popular services provided by Armstrong Simmonds Architects:

• Loft extension. This involves modifying the roof, expanding the space, installing panoramic floor-to-ceiling windows, and more. As a result, loft can become a study or an extra bedroom;
• Basement Expansion. Clients will get additional living space that can be converted into a gym or home cinema;
• Outbuildings. These can be either single-storey or two-storey. A popular solution is to extend the kitchen or living room in this way.

All these trends are actively embraced and implemented by our studio, Architect Armstrong Simmonds. We are always happy to collaborate and ready to bring any residential project in London to life.
