The existing house, designed over 25 years ago, is a freehold end-of-terrace family dwelling arranged over three storeys, with an additional terrace and mezzanine level within the roof space.
The property was built within the curtilage of the London Hydraulic Power Company Pumping Station—a Grade II Listed Building.
Planning permission has been granted for remodelling the existing roof and adding a conservatory at terrace level, converting the ground-floor garage into habitable space, inserting two new windows to the rear elevation, introducing an integrated solar green roof system.
Thanks to the difference of level of around 3 meters from the current ground floor – accessible from the courtyard on the North-East side of the building - and the street level on the South-West side along Canada Estate, it will be possible to create a new basement level, underneath the current ground floor, benefiting of a window towards Canada Estate, improving natural light and ventilation for the room at this level.

The planning drawings describe the general scope of the project as follows:
The scope should allow for the following additional measures:

The proposed flat roof allows to optimise the use the whole footprint at loft level, which is currently restricted to the central section under the ridge. The side glazing is frosted to address any privacy concerns. The conservatory maximise the flexibility of the top level, integrating internal and external space, to be used as amenity space and occasionally as guest room.
The set of drawings below is an update in comparison with the planning drawings reflecting recent conversations, although it is subject to some further adjustments.
