A four-bedroom chalet bungalow in Selby Gardens, Uckfield, could be demolished and two new homes built in its place.
The two new homes would be smaller than the existing one at Totland but documents submitted with the planning application say they represent a considerable increase in density for the site.
A planning, design and access statement says the existing property, while still habitable, is in a poor state of repair, has suffered subsidence and is generally of sub-standard construction.
The new homes would be of a size to accommodate growing families, built to a high standard and be economical in ownership.
They would have a contemporary look, with flat roofs, rendered walls and grey and oak highlights.
The statement says: “We feel the houses sit well and make a better use of the width of the plot.
“The overall scheme would have a fresher, more modern feel and would complement the already eclectic mix of housing in the locality.”
The existing access would be widened and extended to provide for easier movement into and within the site boundary.
Uckfield Town Council says the application is an overdevelopment of the land, out of keeping with neighbouring properties. Councillors are also concerned about the condition of the private road.
Two neighbours have objected on similar grounds to the town council. They are also concerned that provision for eight vehicles to park would greatly increase the volume of traffic on Selby Gardens, an unadopted, narrow rough road where there are already turning problems.
