Seema Malhotra has bemoaned the lack of office space in the west of the borough after moving her constituency base to Hounslow Civic Centre.
The Feltham and Heston MP says she opted to rent an office at the council's HQ, in Lampton Road, Hounslow, 'as a last resort' after exhausting all other options.
The Labour politician has to leave her existing local office at Labour Hall, in Manor Place, Feltham, as the building is being redeveloped.
She said she had searched far and wide for an alternative base in the area but had found nothing which was both affordable and sufficiently accessible for constituents.
She admitted it was not ideal to be in the same building as the Labour-controlled council, which could lead to criticism she is too close to the very organisation she is meant to help hold to account.
"I've been very frustrated by the lack of accessible office space in Feltham and Heston. The need for more office space in the area is something I pushed to get acknowledged in the Feltham Master Plan and it needs to be investigated," she added.
"Taking an office at the Civic Centre is a last resort rather than a first preference, but I wanted somewhere in the constituency which was accessible for all my constituents and this is the most suitable building."
Ms Malhotra is set to move to her new constituency office in two weeks' time. She plans to review the location at the end of her six-month lease.
Constituents will still be able to write to her or call her at her existing parliamentary office.
