COASTAL DWELLING (Refers to image 1)
The existing dwelling on this coastal site was an archetypal 1960's four bedroom house. The property was in a dilapidated condition and LCA was commissioned to design a replacement dwelling that took full advantage of this large site and the distant sea views.

One of the initial tasks completed in the design of the new dwelling was to assess the orientation of the new house within the site. The proposal developed was a 'butterfly plan' with the centre body of the plan predominantly south facing, to maximise solar gain. Large roof overhangs to the fully glazed first floor gables and external louvres to the ground floor provide solar shading to any large areas of glass. This form avoids the uncomfortable heat gain that may result if the whole of one side of the house was south facing, but also facilitates generous and unhindered views to the sea.

The project is currently on site.

CROWN COTTAGES (Refers to image 2)
The works to Crown Cottages were focused on improving the thermal performance, comfort and running costs of a pair of semi-detached Crown Estate cottages. The works were targeted to enhance the Energy Performance Rating of the properties and consequently to benefit the economy of energy use, carbon footprint and user comfort.

The cottages, built in 1950, remain largely unaltered from their original construction and consist of cavity brick faced construction, concrete tiled pitched roof, metal Crittal type windows and solid ground floors. The properties had limited central heating, served by coal fuel burners with back boilers. Hot water was delivered directly from uninsulated storage tanks.

The scope of the works to the properties was informed by an assessment of the existing building using a Sustainabilty Matrix developed by LCA for the project. Application of the Matrix provided an analysis of the existing building and an assessment of the economic and practical viability of various improvement options, upon which design decisions were made.
