Why it was refused

  1. The rear roof extension, as indicated on plan numbers 357LHS/01, 357LHS/02, 357LHS/03, 357LHS/04 and 357LHS/05, by reason of the excessive bulk, height and massing of the rear roof extension results in an overly dominant, visually awkward and contrived form of development. The extension fails to respect the original hipped roof bungalow form and does not appear as a subordinate or sympathetic addition. The proposal would, therefore, be contrary to Policies LLP1, LLP19 and LLP25 of the Luton Local Plan 2011-2031 and the principles of high quality, sympathetic design 10th August 2026 See Notes for Applicants Attached. TOWN AND COUNTRY PLANNING ACT 1990 TOWN AND COUNTRY PLANNING (GENERAL DEVELOPMENT PROCEDURE) ORDER 2015 Continuation (Forming part of Application No: 26/00595/FULHH within Section 12 of the National Planning Policy Framework (NPPF, or the Framework).
  2. The development, by virtue of the inaccurate details within the submitted document number(s) 357LHS/01, 357LHS/02, 357LHS/03, 357LHS/04 and 357LHS/05, and by reason of the cumulative effect of unauthorised developments and roof enlargements, front gable ended extension and substantial rear roof extension, results in a prominent and visually intrusive form of overdevelopment within the street scene. The dwelling sits forward of the established building line, making the enlarged flank roof slope highly visible from public vantage points. The scale and massing of the roof alterations appear wholly at odds with the generally modest forms of development in the surrounding area. The proposal would, therefore, be contrary to Policies LLP1 and LLP19 of the Luton Local Plan 2011-2031 and the principles relating to maintaining local character within Section 12 of the National Planning Policy Framework (NPPF, or the Framework).
  3. The development, as indicated on plan numbers 357LHS/01, 357LHS/02, 357LHS/03, 357LHS/04 and 357LHS/05, by reason of the height, depth and substantial projection of the rear roof extension, introduces an unduly dominant and overbearing form of development that is highly visible from the limited rear gardens of adjoining occupiers on Leagrave High Street and Chapter House Road. The cumulative roof enlargements materially harm the outlook and general amenity of neighbouring properties, forming an intrusive and disproportionate addition within close rear to rear relationships. The proposal would, therefore, be contrary to Policies LLP1 and LLP25 of the Luton Local Plan 2011-2031 and the principles relating to safeguarding residential amenity within Section 12 of the National Planning Policy Framework (NPPF, or the Framework).
  4. The development, as indicated on plan numbers 357LHS/01, 357LHS/02, 357LHS/03, 357LHS/04 and 357LHS/05, proposes a significant intensification of the dwelling to a five bedroom property without submitting any parking information. The floor plans do not show the depth of the frontage, and the roof and block plans do not illustrate the front extension, making it impossible to assess whether adequate on site parking can be achieved. In the absence of this information, the Local Planning Authority cannot determine whether the development would result in adverse highway impacts. The proposal would, therefore, be contrary to Policies LLP1, LLP31 and LLP32 of the Luton Local Plan 2011-2031 and the principles relating to ensuring safe and suitable access within Section 9 of the National Planning Policy Framework (NPPF, or the Framework). 10th August 2026 C Inwards TOWN AND COUNTRY PLANNING ACT 1990 TOWN AND COUNTRY PLANNING (GENERAL DEVELOPMENT PROCEDURE) ORDER 2015 Continuation (Forming part of Application No: 26/00595/FULHH
