Track Record/Permitted development

New Build/Permitted development/Richmond/ Über Shed

Sometimes it is surprising what is allowed without planning consent under “Permitted Development”. Even in a Conservation Area in the heart of London it can be permissible to build a garden outbuilding up to 2.5m high. HEAT have just completed a rather smart full width garden pod clad in cedar slats at the end of this garden in Barnes. We are looking forward to the planting season to see the garden take shape!

Kensington & Chelsea/Permitted development/ Chelsea house underway

A new project is on site in Chelsea. Principally an internal makeover of a terraced house; all the alterations will be accomplished under permitted development. Internal walls are being removed in the basement to open the space up and allow a new kitchen and family room to be created. Upstairs a fireplace focal point is being created where a chimney breast had been removed.

Islington/Permitted development/ 1930’s Extension

In Highbury there is a curious secluded private road developed in the 1930’s. A slice of idealistic New Town in an urban setting. For this project HEAT opened up the lower floor plan creating lateral living spaces, removing a hideous modern conservatory and replacing it with this sleek glazed extension which complements the linear elevations of the original house. Planning consent was not necessary from Islington Council, as the extension was built under permitted development.

Brent/Permitted development/ Queens Park Success

For this large semi-detached family home in Queens Park, HEAT have obtained planning consent for a roof extension and new conservatory as part of a package of refurbishments and improvements. Some alterations only required a Certificate of Lawful Development, some required planning and conservation area consents. The alterations were subtle, but completely transformed the way that the house is used. The interior design included striking timber panelled bathrooms.

Haringey/Permitted development/ Kitchen Extension Permitted

HEAT have obtained a Certificate of Lawful development for a kitchen extension to an Arts and Crafts house in North London. Combining decoration and modernism, this period of English architecture exerts a lasting influence on contemporary design. Illustration: Vase by William de Morgan.

Brent/Permitted development/ Exercise in Permitted Development

This was a quick exercise on a couple of houses in West London to see what the maximum permitted development would be, without applying for planning permission. The result was surprising – roof extensions and rear extensions were possible, that made the plans work much better. Within a couple of weeks the plans were drawn and ready to start on site without the delays of applying for planning consent.

Project 105


Kensington & Chelsea/Permitted development/ House in Holland Park

HEAT have recently completed the refurbishment of a house in Holland Park, backing onto beautiful park-like communal gardens. A complete refurbishment included programmable lighting, new bathrooms and finishes and a new kitchen. There were improvements to the rear elevation to restore the original proportions of windows. All this was completed without the need for planning permission as the alterations fell within permitted development rights.

Project 089


Camden/Permitted development/ Cottage in the Vale of Health

Sometimes planning consent is not necessary and for a charming detached cottage in the Vale of Health in Hampstead we were able to create an extension and alter the glazing under permitted development rules.

Permitted development is particularly valuable as it allows a much faster start on site, without waiting for planning consent. It can also be used to negotiate with planning authorities. We obtained a “Certificate of Lawful Proposed Use or Development” from the London Borough of Camden which is the pice of paper that you need when you come to sell the house and the lawyers ask whether you have planning consent for that extension.
