Contemporary first floor addition for a bungalow

APS Architectural Design was approached by the client to put forward a design for the construction of a contemporary first floor addition at Holywell Bay, apply for all necessary consents and manage the construction works to completion.

The property lies within the settlement of Holywell Bay, approximately half a mile from the beach. The property resides within a small Cul de Sac which comprises of three bungalow style properties which were constructed in 2002.

The proposal was to construct a first floor addition that would enhance the existing property. The existing footprint of the proposal remained unchanged and changes to the ground floor were minimal. The first floor addition was constructed and finished to a high standard using materials and a design aesthetic which is typical of the property's coastal location. The proposal's structure was investigated to check it's feasibility alongside the existing structure. To ensure optimum habitable space at first floor and to minimise the increase in ridge height the pitch of the proposed roof trusses have been reduced to 22.5˚ (for the lower section of roof). Initial sketch elevations were drafted and it was realised that to assist with the aesthetics of the proposal, the ridge level of the proposed roof trusses which form the gables running north to south had to be increased by a further 375 mm.

The vertical elements of the pre fabricated trusses which form the first floor external walls are clad externally using horizontal Western Red Cedar ship lap boarding and insulated to the current Building Regulations standard. Soffits and fascias along with Gutters and down pipes are anthracite PVCu. 780 x 1400 mm Velux roof lights have been used throughout the proposal, all windows at first floor are grey anthracite PVCu.

The front gable comprises of a main glazed area 2350 mm in width from floor to the vaulted ceiling. Vertical aluminium privacy louvres have been incorporated within the design to minimise overlooking, the louvres are supported by the existing ground floor bay dormer at the foot of the aluminium louvres and by the proposed fascia/soffit detail at the head of the aluminium louvres. The front dormer opens out on to a modest balcony and is guarded using stainless steel and glass balustrading. Box dormers front and rear finished in Grey Hardiepanel board are minimal in appearance and consist of a concealed flat roof and gutter finished in Sarnafil lead grey single ply roofing membrane with the external walls finished in Grey Hardiepanel board.
