Replacing a conservatory offers an opportunity to rethink how the adjoining rooms work. At Greenway in Berkhamsted, our design brings the kitchen and dining area into a more connected rear space, with a vaulted ceiling, three rooflights and doors onto a reconfigured patio. The separate living room at the front remains, giving the home a choice between shared activity and a quieter room.
Dacorum Borough Council granted householder planning permission on 26 August 2026, under application 26/01545/FHA, for removal of the existing conservatory and its replacement with a single-storey rear extension.
A kitchen and dining space shaped around daily use
The existing arrangement separates the conservatory from the kitchen and living accommodation. The proposed layout opens up the rear of the house, positioning the dining table in the projecting garden-facing part of the extension and the kitchen alongside it. The connection between them allows cooking, meals and conversation to share one space.
Practical storage is built into the arrangement. Removing the kitchen chimney breast makes room for full-height cupboards incorporating a washer and dryer, while another deep cupboard accommodates the fridge and freezer. A ground-floor WC and coat storage sit nearer the hallway, keeping those functions close to the entrance.
The front living room is retained as a separate room. That balance is useful in a home extension design: the rear can become more sociable without requiring every ground-floor activity to take place together.
A vaulted roof that belongs with the house
The site is within Berkhamsted Conservation Area, so the roof and external finishes are central to the design. A pitched roof over the projecting dining area meets a sloping roof over the kitchen, echoing forms already present on the house and neighbouring properties.
Three rooflights bring daylight into the rear accommodation from above. The vaulted ceiling makes the roof form part of the interior, rather than treating it only as an external feature. Garden-facing windows and patio doors provide additional light and views, with the doors opening towards the side of the reconfigured patio.
Brickwork below the window sills, pebble-dash finishes above and matching roof tiles relate the extension to the existing building. The proposed windows use a timber-style appearance. These choices reflect our approach to extensions in conservation areas, where the details of a new addition need to work with the character of the property.
Responding to the terrace and its neighbours
The projecting part follows the depth of the existing conservatory. Along the other side, the design retains separation from the neighbouring house across the existing side access. These relationships informed the extension’s shape and its approach to neighbouring outlook and daylight.
The project went through pre-application discussions before the householder submission. The decision notice records that this early engagement led to improvements to the scheme. It is a useful example of how planning advice and design development can inform a proposal before a formal decision.
Permission requires the works to follow the approved plans and specified materials. The subsequent building regulations design coordinates the roof, structural openings, drainage and thermal performance. These details are particularly relevant where a vaulted roof and several glazed openings meet the existing house.
