PLANS have been submitted to demolish the toilet block at the car park at Kynance Cove and replace it with a new visitor information point.
It is proposed to build two new buildings, similar to shipping containers, but clad sympathetically in wood.
They would be removed entirely from the site during winter, it is proposed.
The National Trust has applied to Cornwall Council for planning permission for the work, which is now under consideration.
The trust's general manager for the Lizard, Alistair Cameron, said: "We've had various landscaping projects at the cove over the years. What we want to do now is take that landscaping project a step further.
"We inherited the toilet block from the then county council five or six years ago as they were looking to close them down.
"It's a 1960s' block and quite frankly not fit for purpose."
He said the current wooden removable buildings for the car park attendant would also be scrapped and that the two new buildings would be taken away during the winter season.
Mr Cameron added that the existing toilet block is closed during winter anyway but there is a toilet down in the cove.
The consultation period for the application closes on Wednesday.
The car park is in an Area of Outstanding Natural Beauty and a site of special scientific interest. The area is also common land.
