Why it was refused

  1. The proposed development, by reason of its design, bulk and massing, would result in an overly dominant and visually intrusive form of development that fails to appear subordinate to the host dwelling. The proposal would harm the character and appearance of the original building and the street scene, resulting in an unsatisfactory standard of development. 8th May 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: 26/00007/FULHH The proposal is contrary to Policies LLP1, LLP19 and LLP25 of the Luton Local Plan 2011- 2031, which require development to be of high-quality design, respect the scale and proportions of the original building, and respond positively to local character.
  2. The proposed development would introduce an unacceptably cramped form of development through the reduction of spacing between properties, which would be out of keeping with the established pattern of development and harmful to the character and appearance of the surrounding area and users of Mountfield Path. The proposal conflicts with Policies LLP19 and LLP25 of the Luton Local Plan 2011-2031, which seek to ensure that extensions do not represent overdevelopment of a site or harm the character and spatial qualities of the surrounding area. ADVISORY: If this is your first submission for this form of development, before making your re-submission, we recommend that you seek formal pre-application advice to assist in addressing the concerns raised in the assessment of this application. Please note that any such advice may not guarantee an approval. Details of this service can be found on the planning pages of the website Part 2: Biodiversity Net Gain – Information on Statutory Requirement The effect of paragraph 13 of Schedule 7A to the Town and Country Planning Act 1990 is that planning permission granted for development of land in England is deemed to have been granted subject to the condition (biodiversity gain condition) that development may not begin unless: (a) a Biodiversity Gain Plan has been submitted to the planning authority, and (b) the planning authority has approved the plan. The planning authority, for the purposes of determining whether to approve a Biodiversity Gain Plan, if one is required in respect of this permission would be Luton Borough Council. There are statutory exemptions and transitional arrangements which mean that the biodiversity gain condition does not always apply. These are listed below. Statutory exemptions and transitional arrangements in respect of the biodiversity gain condition.
