The Abington Park Cafe looks unlikely to get a second, larger, extension after the latest plan, by the councillor who runs it, was recommended for refusal.
Councillor Tony Ansell (Con, Abington), submitted the new plan for a single-storey extension with an outdoor furniture store.
The Guildhall committee had already approved a smaller extension - without the furniture store - in January, which would increase the footprint by 42 per cent.
But officers said the fresh proposal - which would see a 63 per cent increase in size - would be too intrusive in what is a conservation area.
The planning report said: “It is considered that the larger extension now proposed, whilst appropriately designed in terms of how it continues the existing roof form, would result in a building of an excessive scale and which would consequently appear as an unduly visually intrusive feature within the Conservation Area to the detriment of the appearance of this.”
A resident also objected to the plan saying: “The application is unattractive and out of keeping with the conservation area.
“[There is also] a mishmash of materials on one face of the building.”
The previously approved plans for the smaller extension, which are being funded by the business, will include a new kitchen area, office and food store, providing more space for food preparation and serving.
