Enforcement Notices

ENF/0480/24 – 3 Milnefield – Roof not constructed to approved plans.
EN/0047/24 – 25 Sylvia Avenue – Breach is of section 2 of the 1979 Ancient Monuments and Archaeological Areas Act. Hardstanding and fencing including concrete on and into monument. Council officers are to attend No25, on the 23rd October.  Conservation are currently also liaising with Historic England on this matter and whether legally they can enforce historical breaches within the monument as well.
EN/0034/23 –5 Wellington Avenue – noncompliant with Granted plans Building footprint and height and windows assessed. Developer has proposed minor adjustments to make it acceptable to immediate neighbours; however, the building is still not compliant with the approved plans. The Council are still of the opinion that the owner is required to submit a full planning application for the proposed alterations: Enforcement team visited this month and state that they have initiated formal action and are looking to serve a Breach of Condition Notice..
EN/0132/25 and ENF/0337/19/P – Road and barn on Green Belt on fields lying north of Roger Bannister Rugby fields. (Oli Farm – see PL/1930/24).  Enforcement notice issued for 8.2.2020 failure to comply. This has now been granted permission for an agricultural barn to be constructed.
ENF/0603/14/P – Farmland to the rear of Grimsdyke Lodge: The S215 Notice gave them until 15.2.2019 to remedy the condition of the land. We requested why the enforcement has not been initiated. We reported further commercial fly tipping on the field and Enforcement team inspected the site on Monday 20 April and are considering a further S215 enforcement notice. The field is in a very poor state and could bring the threat of relegation to grey belt and future development.
