We are once AGAIN calling on the London Borough of Hillingdon to REFUSE the latest amendments to planning application 79535/APP/2026/11.

This is no longer simply a dispute about an overdevelopment proposal. It is about the severe and ongoing harm being caused to neighbouring residents through unacceptable loss of privacy, loss of light, overbearing impact, prolonged disturbance (ASB) and the continued failure to protect residential amenity in accordance with the Hillingdon Plan.

For the past nine months, neighbouring residents with gardens only 9m long, have endured:

• Continuous disruption and construction disturbance
• Loss of peace, privacy and quiet enjoyment of their own homes
• Ongoing stress, anxiety and exhaustion
• Building works taking place outside permitted hours, including building activity continuing until 2:45am, for which video evidence exists
• Sleep disruption and significant impacts on daily wellbeing and quality of life

Residents are exhausted. This situation has become intolerable and cannot be allowed to continue indefinitely. Despite repeated applications, withdrawals, objections and amendments, the developer has continued pursuing revised applications rather than addressing the fundamental planning harms he knew existed when purchasing the property and planning his proposed development. This has subsequently been repeatedly identified by residents and flagged as contravening established planning policy. While the latest amendments appear some what closer to what has physically been constructed without permission, this does not resolve — nor justify — the substantial harm already caused by the unauthorised build. The amended plans still:

• Propose an excessive, dominant and overbearing form of development
• Result in severe overlooking and an unacceptable loss of privacy to neighbouring homes and gardens
• Introduce more rear-facing clear opening windows at an approximate separation distance of only 10 metres from neighbouring residential properties, substantially below the 21 metre guidance set out within the Hillingdon Plan for protecting privacy and residential amenity
• Fail to accurately reflect that the extension has been constructed significantly higher than originally approved and upon a newly raised patio level, significantly intensifying the overlooking impact upon neighbouring properties
• Fail to properly represent the original and altered site levels, including an estimated two-foot increase in ground level caused by deposited builders’ waste and raised land levels, materially worsening the real-world impact on neighbouring residents
• Create an oppressive sense of enclosure and visual dominance
• Cause additional loss of daylight and outlook to neighbouring homes, including properties benefitting from established Right to Light protections within their deeds!

These are not minor or technical concerns. Residents are effectively losing privacy, natural light and the ability to peacefully enjoy their homes and gardens 

There are also growing concerns regarding the apparent intensification of the property. The replacement of one large clear opening window at the rear with two smaller clear opening windows. This raises legitimate concerns regarding the future subdivision or intensified use of the loft space. This element was previously rejected within earlier submissions, and residents are deeply concerned that the development could facilitate increased occupancy levels, including the potential for future multi-occupancy use (HMO), placing additional pressure on neighbouring homes and residential amenity.

Residents are deeply concerned about the implications for:

• Noise and disturbance
• Privacy and overlooking
• Increased occupancy and intensified use
• The long-term character, livability and residential amenity of the neighbourhood. 

This prolonged process has also exposed serious concerns regarding the handling of the application itself. The development has gone through repeated cycles of refusal, withdrawal, resubmission and amendment, forcing residents to repeatedly:

• Re-engage with the planning process
• Submit further objections
• Relive the stress, uncertainty and disruption caused by the development

Residents should not be subjected to an endless cycle of amended applications where the core planning harms remain fundamentally unchanged. At some point, a clear and decisive line must be drawn in the interests of fairness, public confidence and proper planning control.

This is no longer just a planning matter — it is a human one. Residents report serious impacts upon:

• Mental health, relationships  and emotional wellbeing
• Sleep, WFH and day-to-day living
• Their long-term sense of comfort, safety and security within their own homes
• Two residents have developed what their GP's have called stress-related health conditions during this prolonged process.
• One resident is facing these ongoing impacts whilst living with an advanced incurable illness.
• One resident has put their home on the market. 

Families who have lived peacefully within this community for many years now feel overlooked, ignored and worn down by a process that appears to prioritize repeated amendments over the protection of existing residents.

We are therefore calling upon Hillingdon Council to:

• Uphold the policies, standards and residential protections contained within the Hillingdon Plan
• Properly apply planning policies relating to overlooking, residential amenity, overdevelopment and site levels
• Put longstanding residents and neighbouring amenity first
• REFUSE this amended application
• Recognise the cumulative and ongoing impact this development has had upon neighbouring residents
• Require the removal of all rear clear opening windows impacting privacy
• Require the garden and patio levels to be restored to their original approved levels
• Protect the character, privacy and livability of this residential neighbourhood
• Prevent continued cycles of amendment where the fundamental planning harm remains unresolved

This development, in its current form, is not — and has never been — acceptable.

 Our homes should be places of privacy, comfort and security — not places where residents live under constant overlooking, disturbance, stress and loss of wellbeing.

We ask residents, supporters and the wider community to stand with local families to support us. Please SIGN and SHARE widely. What is happening here could happen to any resident, any family and any neighbourhood if planning rules and protections are not properly upheld.
