Eighteen new homes would bring chaos and congestion to a Morecambe street, say residents.
Plans to build 10 two-bedroom houses and eight one-bedroom flats are being opposed by people who live on King Street, a small cul-de-sac just off Euston Road near the town centre.
Around 20 residents have put in written complaints to Lancaster City Council, who will have the final say on the proposals by Morecambe-based Milli Developments Ltd.
A bungalow and a garage at the end of King Street, close to where the railway line runs, would be demolished to make way for the development.
Jean Burton, a resident of King Street, said: “I don’t think it’s a good idea.
“This is not a wide road. You can’t pass on it. Lots of people park down here. It’s often blocked by delivery vans.
“Eighteen new houses means there could be a possibility of 36 extra cars.
“There are a lot of young children who play out in the road who have nowhere else to play. It’s going to be congested.
“People come down here with scaffolding and they are stuck on the road forever.
“The exit onto Euston Road is awful. People on nearby streets are also up in arms about it too.”
Councillor Mark Bevan has also written to the council in support of residents.
A report by architects Harrison Pitt says the end of King Street would be remodelled to allow easier vehicle movements.
It also says the new homes would have a modern design and be arranged in semi-detached pairs, with back gardens facing the railway line.
The city council is expected to make a decision on the planning application later this year.
