An appeal has been submitted to the Planning Inspectorate after Middlesbrough councillors refused an application to convert a large Marton house into three separate flats.
What was proposed
The applicant, Harkin Associates, sought permission to divide a four‑bedroom semi‑detached dwelling on Gypsy Lane into three self‑contained units — two at ground floor level and one on the first floor, each with its own entrance. The project would have involved the demolition of a detached garage and the loss of three parking spaces, alteration of two rear gardens, changes to the driveway and associated landscaping, and the erection of a cycle store and fencing.
Council officers backed the conversion
Council planning officers recommended approval. Development control manager Andy Glossop told councillors the site was in a sustainable residential location close to Marton shops, pubs and a school and was served by a main thoroughfare. Officers considered the proposed rooms to be of "sensible sizes" and judged there would be adequate parking provision.
Local objections and councillors' decision
The application, which was originally lodged in 2025 and debated at a planning meeting on 12 February 2026, drew a number of objections. Sixteen written objections were recorded, including letters from two ward councillors; one letter supporting the scheme was also received. Objectors raised concerns about a change of character for the area, over‑development, impacts on existing residents, and increased traffic and parking pressures.
Against the officers' recommendation, eight members of the planning committee voted to refuse permission. The summary of the council's decision available on the planning portal states the proposed splitting of the property would represent a change to the way the dwelling would be used and would result in... (the publicly available summary on the portal is truncated at this point).
"growing demand"
Appeal to the Planning Inspectorate
Nearly six months after the committee's refusal, an appeal has now been lodged with the Planning Inspectorate. The appeal submission argues the scheme complies with Middlesbrough's Local Plan and points to a growing demand for smaller housing units in Marton and across the borough.
The final determination now rests with a planning inspector, who can uphold the council's decision or overturn it on the grounds of planning policy, material considerations or procedural matters. The submission of an appeal means the site could yet be developed in the manner proposed if the inspector finds in favour of the appellant.
Why the case matters locally
The dispute highlights recurring tensions in Middlesbrough between the drive to increase housing supply and concerns about the impact of changes in use on established residential streets. Decisions on small‑scale conversions can set precedents for similar proposals elsewhere in the town, influencing parking, street character and the mix of dwellings available to residents.
- Location: Gypsy Lane, Marton, Middlesbrough
- Proposal: Convert 4‑bed semi into 3 self‑contained flats
- Applicant: Harkin Associates
- Council decision: Refused by planning committee on 12 Feb 2026 (8 votes to refuse)
- Next step: Appeal lodged with the Planning Inspectorate
| Issue | Detail |
|---|---|
| Officer recommendation | Approve (sustainable location; rooms of sensible size; adequate parking) |
| Public responses | 16 objections, 1 letter of support |
| Council reason | Refusal cited change of use and impact; summary on portal is incomplete |
The appeal will be considered on its planning merits by an inspector appointed by the Planning Inspectorate. Until that process concludes, the site remains subject to the council's refusal but the outcome now depends on national planning appeal procedures rather than the local committee.
