Plans for a new development

Read about how Base Energy are working with SJT Developments Limited on their new three-storey apartment block containing 28 residential dwellings!
Land at Long Road, Canvey Island


Base Energy are working alongside Marden Homes Limited and SJT Developments Limited to make sure the proposed apartment block complies with the BRE guidance.

The existing space is currently occupied by grassland and trees. It is located at the back of an Iceland Foods store and is surrounded by residential dwellings. The proposals are for a three-storey apartment block containing 28 residential units, communal areas and garden space.

The Story

Base Energy were brought on board to provide an expert Daylight Report in line with the National and Castle Point Borough Council planning requirements. The purpose of the report was to assess the potential impact to any neighbouring properties.

Concerns were raised that the daylight levels of surrounding residences would be affected by the construction of the apartment block due to the close proximity of the buildings. There were several dwellings to the rear of the proposed development and in total we had to assess 19 relevant windows with fears that these windows would suffer an unacceptable reduction in natural light.

The Solution

Our specialist Daylight assessors created a complex 3D model of both the existing and proposed sites to assess the daylight levels using a method called the ‘Vertical Sky Component. The analysis allowed our assessor to compare the amount of available light that falls directly on the centre of an opening. If the opening retains at least 80% of its former daylight level, then it is deemed acceptable.

Results showed that all windows had a negligible reduction in daylight levels, due to the proposed neighbouring development. This led to the conclusion that the development satisfies the requirements as set by BRE.

As such, the project was able to go ahead without the worry of facing any objections to planning.
