What makes Greenwich Special?

Greenwich, a bustling borough in the UK, offers a captivating blend of history, culture, and architectural diversity. Greenwich is famous for its architectural scene and experiences buildings ranging from grand historic structures to modernistic structures.The borough is best known for its classical architecture – the old Royal Naval College being a prime example of Baroque architecture. The Queen’s house stands as another example of Palladian architecture in the area, acting as a symbol for symmetry and classical proportions.

The residential scene in Greenwich is ever-evolving with the place offering a fascinating mix of period properties and modern homes. Features of the Georgian home in the area will include elegant facades, symmetrical designs, and classical detailing. The Victorian is generally more ornate, with spacious layouts and decorative brickwork. Edwardian properties will have significantly bigger windows and a more understated design. In recent years, modern developments, particularly along the riverside, have introduced sleek, minimalist designs with open-plan interiors and energy-efficient materials, seamlessly integrating contemporary living with Greenwich’s historical character.

There are many historic buildings in the area that have conservation status, ensuring that their unique character is preserved. Yet there is an awfully strong trend towards adaptive reuse whereby old industrial or historic buildings become modern homes, offices, or cultural venues. Such a course of approach keeps the architectural heritage in place while providing for contemporary needs.

Our Experience in Greenwich

As architects deeply embedded in Greenwich’s architectural scene, Extension Architecture offers more than just design; we create transformative spaces that enhance both lifestyle and surroundings. For architectural projects within the Greenwich Council area, we begin with a comprehensive property site assessment. This evaluation delves into the property’s history and its surrounding environment, ensuring adherence to all relevant regulations for your planned construction or redesign.

During the design phase, we prioritise staying current with all regulations, with particular attention to nearby conservation and heritage sites. For projects in sensitive areas, we develop thoughtful proposals that respect the unique character of the surroundings.

Planning application rules and building regulations can differ from one council to another. Our team is committed to staying informed about any updates specific to Greenwich Borough. Additionally, we analyse the approval and refusal patterns of other properties in the area, which enhances our understanding and supports our exceptional success rate.

House Extensions

Having dealt with more than 100 applications in the area, we like to consider ourselves as an expert when it comes to house extensions including single storey, double storey extensions, loft conversions and much more.

In one of our recent projects on Foyle road, the client wanted a single storey extension in order to get a bigger kitchen and home-office without disturbing the existing home at all.

More about us

HMO and Flat Conversion, Greenwich

Extension Architecture has also worked on flat/ HMO conversions in their 16 years of experience. A few years ago, EA was approached by a developer to convert his existing 4 bedroom residential unit into multiple apartments, and our director and team of planners recommended an extension in order to maximise the rental potential of his property.

We proposed to retain the existing retail unit on the ground floor, however, extend vertically by means of a mansard style additional storey, and to the rear, almost doubling the existing floor area and increasing rental potential by a huge 500%! The site, being located in a prime commuter area, was sure to have a great level of interest from potential future occupants.

The entire frontage was redesigned and modernised using zinc cladding with the aim of uplifting its appearance, making it a positive statement on the area. The council welcomed the proposal because of its interest in providing a positive contribution toward improving living conditions and also for being a high-quality design. The credibility of the project was on a firm footing from the outline planning consent due to the extra units. The development, with rear extensions and internal reconfiguration, yielded 6 self-contained units having 3 two bedroom and 3 one bedroom flats. Using our knowledge of planning and site constraints, we were able to increase the proposed GIA to 366 sqm of residential and 89 sqm of commercial floor space, over and above the original 2015 application.

New Build, Greenwich

Extension Architecture has been especially opportunistic to work on numerous commercial projects with the Greenwich council including development of a health and wellness centre, club house, banquet hall, galleries and accommodation. This has filled us with immense knowledge about the right way to develop drawings to receive grants on planning permissions when working with the Royal Borough of Greenwich.
