Two of the rejected Twickenham riverside development competitors have joined forces as they urge Richmond Council to reconsider its plans.

The Regency era inspired proposals, including an arcade of shops and up to 40 homes, was met with negativity from residents in the official consultation.

Of 778 people surveyed, less than 10 per cent of respondents said they thought the proposals from architects Quinlan and Francis Terry were a ‘good idea’.

Community group Twickenham Alive, who want to see a lido on the site, and architects Kemp Muir Wealleans have combined elements from their rejected plans to announce a new concept for the riverside.

A spokesman for Twickenham Alive said: “A business proposal to develop the lido is with the Council from the Bristol Lido organisation.

“A senior executive from an international organisation has confirmed an offer to fully fund the remainder of the site as they like what we are proposing for Twickenham Riverside.

“This offer could mean that the council could recoup their £6m spent on purchasing the site and not cost the borough a penny and also help to rejuvenate Twickenham’s town centre.”

It is believe the other competitors in the council’s competition to design the King Street and Water Lane site were Adam Architecture, John Simpson Architecture and Atkins, who worked with Twickenham Alive.

The alternative proposals have so far not been released to the public by Richmond Council but are subject to a Freedom of Information request by this newspaper.

Cabinet member for environment and business said she would “consider” making the plans public, while council leader Lord True said it could be “commercially insensitive” to do so.

Deputy leader Councillor Geoffrey Samuel added: “It is too late [for alternative proposals] but what I do know is that Quinlan and Francis Terry are prepared for much more far reaching provisions than have been made public.

“Not every issue can be addressed but a lot of them will.”

A petition from Eel Pie Island residents was presented by Councillor Susan Chappell at a council meeting last month, which gained more than 800 signatures.

The Eel Pie Island Association opposes the scale of the development and the access it provides to the river, while businesses raise concerns over the design and potential for future development.

Architect Henry Harrison, who lives on the island, said: “The proposed development of the remaining land along the lines of the Quinlan and Francis Terry scheme is a triumph of megolamania over common sense.

“Clearly this land is a development site, and would be recognised as such if it was referred to a higher government level for determination.”

What was in the council’s January 2015 brief to architects?

• Introduce a town square on King Street and at the top of Water Lane, and one that is sufficient in size to support local market activity

• Introduce the opportunity for niche restaurants, retail, arts and crafts, and commercial activity within the overall scheme and be complimentary in style and formation to surrounding retail streets, specifically Church Street, Twickenham. Including the opportunity for alfresco/cafe dining activity

• Potential for ‘front of house/reception’ for council services to be provided

• Connect to, and be complimentary of, existing properties not within the ownership of the Council on King Street and Water Lane.

• Include a proportion of residential including shared ownership options

• Introduce, as appropriate, further open space to provide for the relevant connection to existing open space and access to the Diamond Jubilee Gardens • Create an area for performance on the Embankment (amphitheatre)

• Consider a current/future opportunity to connect with, and develop, the access road at the rear of King Street, with the potential to establish retail activity that is complimentary to the overall site

• Introduce facilities that could be available for community use including café, toilets, room to hire.
