Sehra handles Mayfair/Harley Street mews and townhouse casework with a strong medical/office-use and heritage-fabric focus. He is consistent about mapping a listed building's development history (when it was reconfigured, which parts date from later alterations) to justify why internal demolition of 'modern fabric only' is acceptable, while significant historic spaces (a double-height ballroom, for instance) are protected outright. He records negotiated basement/plant schemes in detail, crediting specific revisions (retaining more historic door/window openings, switching to a lightweight glazed infill roof) that followed officer comment during the application, and is thorough on rooftop plant/terrace noise assessment, naming each nearby noise-sensitive receptor and its distance from the source.
· maps a listed building's alteration history in detail (when reconfigured, which parts are later/no-interest additions) to justify which areas can be altered and which are protected
· credits specific negotiated design revisions during the application (retained openings, changed roof form) that followed officer comment, describing the 'before' and 'after' explicitly
· for rooftop plant/terrace noise, names each nearby noise-sensitive receptor property and its approximate distance from the source rather than a general amenity statement
· treats a temporary-permission condition's end date and reversion use as a live constraint on the current application rather than incidental detail
· what this officer's reports consistently look for: which parts of a listed building's fabric are historically significant versus later, no-interest alteration, mapped against the building's known development history
· what this officer's reports consistently look for: the specific 'before' and 'after' of a scheme negotiated during the application, not just the final version
· what this officer's reports consistently look for: each individual noise-sensitive receptor near a proposed plant installation, named and distanced from the source
“The upper floors of the mews have been altered and today form open plan offices with no features of interest. The ground floor entrance area has also been altered. The proposed internal demolition relates to modern fabric only and is, therefore, acceptable.”

“Following negotiation more of the historic door and window openings have been retained, and the roof of the infill has been changes to a lightweight glazed roof.”

“The nearest noise sensitive receptors were identified as being residential properties in 36 Hay's Mews - (19m away); Roseberry Court - (7m away); Roseberry Court facades to the south east facing the plant - (24m away) and 15 Hay's Mews - (10m away).”
