A couple’s plan to fit double glazing at their Grade II listed Marlow home has been refused.

Mr P and Mrs K Beyer applied for the changes to their 18th century ‘Dial House’ on St Peter Street, Marlow.

However, planning officers claimed that replacing existing windows with double glazed timber ones would ‘not protect or enhance’ the property.

In a decision notice handed down this week, they said: “The proposal represents unacceptable additions where original fabric would be removed and negatively impact the listed building.”

The couple said in their application that the choice of ‘traditional’ timber windows would match the existing ones and that their proposals aimed to secure the long-term future of a ‘family home’.

They also argued that the double glazing would significantly reduce energy consumption and ‘improve the thermal quality of the building’.

They wrote: “If this proposal is approved, all the house windows will match and will all have the same thermal efficiency and security values.”

However, planners said the proposals conflicted with planning policy, adding that the agent and applicants were repeatedly given clear advice on what would be acceptable on several occasions.

They said: “The agent did not wish to amend the application.”
