    Central Brighton

The brief

Change, replace or alter the existing three pairs of French doors and one window to provide workable ventilation for all the habitable rooms and re-arrange the interior to make the best use of the limited space. The property is listed and any works needed both Listed Building consent and planning approval.

The property

The property is a single aspect basement flat at the front of Sillwood Mansions a Grade 2 listed terraced house built in 1829 in the centre of Brighton. It is accessed by separate steps leading down to the entrance at basement floor level. The flats three doors and one window openings are flat arched, they follow the line of the fenestration above and they form a significant element of the front façade of this important heritage building.
The doors were not original and their style did not match anything in the rest of the building. The one remaining window was a boxed sash window but the top no longer existed and had been replaced with two opening casements. None of the fenestration provided adequate or secure ventilation to the living room or the bedrooms which they served.
Internally the layout was very different from the original ‘servant quarters’ and the primary aim was to maximise the useful space in the flat.

The solution

The flat is part of an iconic Listed Building and it was critical that any external changes enhanced the historic front elevation. The openings and principle elevation were maintained but the existing doors and window were replaced with a pair of French doors (forming the front door) and three double-hung vertical sliding sash windows. The doors and the windows were timber of a style reflecting the period and all with a glazing bar pattern matching the windows above.
Internally, walls were straightened, a second WC/shower room added and cupboards built using existing alcoves, spaces, and corners.

The result

Externally, the basement is now in visual harmony with the rest of Sillwood Mansions, the lines of the windows and doors flow from one floor to another. The new doors and windows provide secure ventilation to all rooms and inside the space works efficiently and is clutter free.
