Highgate Extension

Renovation and Extension

Our clients had lived in this modern house in the Highgate Conservation Area for a few years when they contacted us. With a growing family, the house was in need of refurbishment and extension to give them the space they needed. A key part of the project was to bring more light in to the ground floor and to structurally open it up to make an open-plan space.

Interior Design and Alterations

The concept was to split the open plan space into three zones. The new kitchen was planned to the side of the space with it’s own door to the garden and a separate pantry space accessed from inside. The main family space for relaxing and watching TV is in the middle of the space. While the existing rear wall of the house was removed and a new ground floor extension built to extend the living space, with space for a large dining table close to the garden.

The whole house was refurbished with new electrics, heating, and decorations throughout. Our clients disliked the existing staircase which was dark and so this was replaced with a bright, open design with glass balustrades. On the second floor a further extension was constructed over part of the roof terrace, to give a new bedroom and study space. The master bedroom suite was also re-planned and refurbished with a new walk in dressing room.

Planning Approval

The design included for the refurbishment of the exterior of the house at the front, including new windows and doors. As well as insulated render, and landscaping and planting design for the front garden. It was important that our design was seen to enhance the Conservation Area, so we made sure that the choice of materials and the detail of the design worked with the Planning Policy. As a result the design won the support of the Highgate Society and the Conservation Officer. And our clients were delighted that the planning application was approved on the first go.

Better Natural Light

The structural changes to the house were designed to open the space to the garden. This results in a living space with much more light, and a framed view through to the garden from the entrance hallway. The staircase was redesigned to be more open, with oak treads and glass edges, adding light to the space. This was extended up to the new bedroom and study space in the top floor extension, and a new frameless glass balustrade fitted on the roof terrace to create a great place to sit and look back over Highgate.


The finished house includes a great new kitchen and pantry, as well as an extra shower and boot room on the ground floor. Lots of extra storage was also woven in to the former garage space. This was an unusually tall space and so we were able to design a mezzanine level to take full advantage of the height and tuck away the main boiler and controls.

Extension Design

The ground floor extension is designed in keeping with the modern aesthetic of the house. While the top floor extension adds huge value to the house by creating an extra bedroom, that our clients can also use as a home office when they do not have guests staying. The extra bedroom has sliding doors giving access on to the roof terrace with fantastic views across Highgate.
