The formal submission of £50 million plans to transform Brighton Marina has been delayed.

Parkridge Developments had hoped to hand over its planning application for the next phase of work at the marina by the end of April.

But it is now expected to be a fortnight until Brighton and Hove City Council receives the plans.

Earlier this month we revealed the first pictures of proposals drawn up by Brighton-born architect Piers Gough for five new buildings at the marina.

These include three 14-storey tower blocks offering a mix of homes and commercial units.

The new buildings would feature a total of 220 homes, with stores like Marks and Spencer and Ralph Lauren lined up for ground-floor spaces.

There would also be a glass complex welcoming people to the marina and a four-storey building in Merchant's Quay.

Parkridge plans to carry out £12 million- environmental and access improvements, including a redesign of the marina's entrance, to make the site more attractive and accessible.

A new transport interchange building would be attached to the existing multi-storey car park, which would be screened in coloured panels.

Residents have welcomed the improvements, but plan to object to the size of the tower blocks.

A Parkridge spokeswoman said: "The final details of the planning application are still being put together. It should be ready within the next fortnight.

"After that, the timescale will depend on the council and how much public consultation they want to hold."
