Farncombe Road: Worthing

What was the client’s brief?

Our client was looking to extend the existing property to create some additional residential units in a busy and popular part of Worthing.

What did Jessey Mason do?

We worked closely with a planning consultant and the client to come up with a suitable scheme.  In the summer of 2017, we received planning approval for 4 flats.  The client is now considering his options of how to proceed.

Bath Road, Worthing

The property is a converted 1920’s house into 2 flats.  The first floor flat had a large roof space, which the client wanted to utilise to provide more family space.

We obtained planning consent for a large open plan living room and created an up-side down maisonette.  We also obtained building control consent and helped liaising with the contractors on site.
