Primrose Hill architect house extension designed by camden architects, with oak kitchen and stone flooring

Architecture for London has completed a number of bespoke homes in the Borough of Camden. Our architects create beautifully crafted properties with a considered design approach. Client involvement at each step of the process is key to creating a truly collaborative project.

At our house extension and refurbishment at Dartmouth Park we designed a large kitchen, barbecue area and a snug with a suspended stove at the rear of the house. The snug is enclosed by a frameless glass box that gives extensive garden views. Large sliding glass fill the new kitchen with natural light. In Fitzrovia we extended and refurbished a Grade 2 listed Georgian property, inserting a new master suite with feature bath. A glazed study extension leads to a first floor roof terrace to the rear. If you are looking for experienced Camden architects, please contact us to arrange an initial meeting to discuss your project.

Our architects work in all parts of the Borough of Camden including our projects Dartmouth Park House Extension in NW5, Primrose Hill house extension in North London NW3, Kentish Town NW5, Fitzrovia W1, Hampstead House Extension and Belsize Park NW3, St John’s Wood NW8 and West Hampstead NW6.

Architects in Camden

With over 10 years of experience in the borough and the surrounding neighbourhoods, our team of architects are highly knowledgeable about working in Camden and the particular planning requirements of the borough.

Sustainability is a key consideration of all of our projects. We work with our clients on the design and material choices to consider the embodied energy and energy performance, while ensuring that our refurbishments maintain the characteristics of Camden’s heritage buildings.

Permitted Development rights in Camden

Permitted development rights allow many household improvements and extensions without the need for planning consent, for example: rear extensions, garden rooms and loft conversions. If you live in a freehold house, then you may have permitted development rights. It’s worth noting however that these rights don’t generally apply to flats or listed buildings.

Be aware of Article 4 Directions – these sometimes exist in conservation areas, they can remove some or all permitted development rights. Camden publishes guidance for each conservation area that makes clear if any permitted development rights are removed.

We would usually apply for a Lawful Development Certificate from Camden to confirm that the proposals are permitted development and therefore planning permission is not required.

“From obtaining planning permission to helping me choose great contractors, AFL were brilliant throughout. They were a pleasure to work with!” – Fatos, Primrose Hill

Camden planning permission

If the works do not fall under permitted development or prior approval, it is likely they will require planning permission. Your architect will need to submit a planning application including existing and proposed drawings along with any other supplementary documentation, which is outlined on the Council’s website.

The Council recommends engaging with a qualified professional to prepare and submit your application, which should be done as early as possible in the design process.

As noted in Camden’s planning Guidance CPG1, in order to achieve high-quality design in the borough, applicants must carefully consider buildings in terms of context, siting, detailing and materials. Camden require proposals to:

  • provide visual interest for onlookers, from all aspects and distances. This will involve attention to be given to both form and detail
  • consider the extent to which developments may overlook the windows or private garden area of another property
  • ensure buildings do not overshadow existing outdoor spaces
  • materials should be selected carefully and should relate to the character and appearance of the area, particularly in conservation areas or within the setting of listed buildings

Building in conservation areas in Camden

Camden has a rich history and a varied built environment. As such, conservation is a very important aspect of Camden’s planning policy. To protect the unique character and charm of the borough’s neighbourhoods, 40 conservation areas span nearly 50% of the borough as shown in the conservation area map below.

Conservation areas are not designated to stop all future development or change but to ensure that change is managed to conserve the historic significance of the area as a whole.

Pre-app advice in Camden

Like most boroughs, Camden Council offers a pre-application service. This is an opportunity to discuss your proposed scheme and obtain written advice from a planning officer before submitting an application. We don’t always recommend this route, mostly due to the time scales involved. For simpler householder projects, proceeding straight to a full planning application is usually our recommended route. We find pre-apps to be more productive on larger schemes, for example on new build houses and multi-unit residential and commercial developments.

Listed building consent in Camden

With a total area of just 21.76km², Camden is one of the smallest boroughs in London. Despite its small size, there are over 5600 listed buildings in Camden. Read more about listed building consent in London.

Our architects have significant experience working with listed buildings in Camden, having recent architectural projects achieved successfully listed building consents for houses at Gainsborough Gardens NW3, Conway Street W1T, Downshire Hill NW3 and Albert Street NW1.

Any material works to a listed building will require listed building consent, whether the works are internal or external.

Rear extensions in Camden

Camden has specific guidance on the design of rear extensions in their CPG1 planning guidance. The Council requires extensions to:

  • be secondary to the building being extended, in terms of location, form, scale, proportions, dimensions and detailing
  • respect and preserve the original design and proportions of the building, including its architectural style
  • respect and preserve existing architectural features, such as projecting bays, decorative balconies and chimney stacks
  • respect and preserve the historic pattern and townscape of the surrounding area
  • not cause a loss of amenity to adjacent properties with regard to sunlight, daylight, outlook, overshadowing, light pollution, privacy and sense of enclosure
  • allow for the retention of a reasonable-sized garden
  • retain the open character of the existing garden and the gardens of neighbouring properties

Basements renovations and extensions in Camden

Camden has specific guidance on the design of basements in their Camden Planning Guidance CPG: Basements

  • Basement development must not cause harm to: neighbouring properties; the structural, ground, or water conditions of the area or the architectural character and heritage significance of the area.
  • The siting, location, scale and design of basements must have minimal impact on the host building.
  • Basement development must be no more than one storey deep and must not exceed 50% of the garden.
  • Applicants will be required to submit information within a Basement Impact Assessment (BIA).
  • In some instances, the Council will require a Basement Construction Plan to be provided.
  • BIAs will require expert independent verification funded by the applicant.
  • An Article 4 Direction requiring planning consent for all basement development covers the whole of Camden.

Camden’s existing built environment

The built environment in Camden is varied, as the borough spreads from Bloomsbury in the south, all the way north to Highgate Village. As it does so, the 18th century urban squares of the great estates become the once rural medieval villages of Hampstead and Highgate, now enlcosed by greater London. Along the way the formal Victorian and Georgian squares and terraces dominate, along with much notable mid twentieth century modernist architecture and newer infill developments.
