"Whereas the application drawing shows a separation distance of 1 metre between the flank wall of the extension and the boundary, the actual separation distance is only 0.45 of a metre which means that the eaves and fascia of the building are adjacent to the boundary with the guttering over hanging number 28 [number 28 being their property]."
"The drawings approved pursuant to the [earlier] planning permission clearly show a single storey extension with a low hipped and pitched roof above. What currently can be seen on the site is totally different, particularly in respect of the height of the walls of the extension on the side boundary adjacent to number 28 and the pitch of the roof which means that the whole structure appears to be substantially bigger, and in particular higher, than what appears on the approved application drawings. The extension is supposed to be 'single storey'. It is certainly not as it stands. The extent of the changes is clearly represented in the [particular] drawing. This shows the pitch of the roof increased from 40 to 44 degrees with a consequent increase in the height of the building by approximately 1.23 metres. It also shows, as accurately as possible, the elevational relationship to Chesham House itself with an originally indicated pitch of 41 degrees to the roof. Whereas in the original plans the ridge was to be in line with the eaves level of Chesham House it is now significantly above."
"We have provided the council with the following irrefutable evidence that the above extension is a two storey building: 1. The building has been surveyed by [some chartered surveyors], and the height is already 7.12 metres (it will be around 150-200 mm higher when completed). The height from our site is approximately 8.6 metres due to the difference in ground levels."
"2. A cross section drawing showing the storey height of the first floor is approximately 2.4 metres (this dimension is easily verifiable from a site inspection). 3. A cross section drawing showing that if the building had been constructed in accordance with its original permission, the first floor accommodation would have been sufficient for storage only and insufficient for use as a habitable room. 4. Photographs of structural first floor joists. 5. Photographs of the opening in the floor joists which has been built and shaped to take a full size staircase, rather than a storage access door (this again is easily verifiable on site inspection). A two storey building is in breach of policy H9 as the minimum side space does not exist and therefore we cannot see any circumstances under which this application should be approved."
"When considering applications for new residential development, including extensions, the council will normally require the following: (i) for a proposal of two or more storeys in height, a minimum 1 metre space from the side boundary of the site should be retained for the full height and length of the flank wall of the building. ..."
"The council considers that the retention of space around residential buildings is essential to ensure adequate separation and to safeguard the privacy and amenity of adjoining residents. It is important to prevent a cramped appearance and unrelated terracing from occurring. It is also necessary to protect the high spatical standards and level of visual amenity which characterise many of the borough's residential areas. Proposals for the replacement of existing buildings will be considered on their merits."
"The amended proposal is to be single storey and no first floor plans have been submitted. The northern flank wall of the proposed amended extension is according to the plans to be located approximately 1 metre away from the property boundary along the northern edge of the application site. The eaves of the pitched roof on the northern flank is to be located approximately 0.45 metres from the northern boundary."
"The council has quite clearly permitted development in conflict with this policy, [that is H9] because: (i) the building is at least two storeys in height. The height from slab level to the ridge is about 7.2 metres which is a full two storeys. Moreover, due to the change in levels between Chesham House and our clients' property, the flank elevation of the building appears as 8.6 metres high when viewed from the latter, which is getting on for three storeys. The building is also sited less than 0.5 metres from the site boundary. The relationship between the building and the site boundary is shown with reasonable accuracy on the plan which accompanied the original application permitted in November 2006. It is clearly much less than one metre. We have noted that had, in the amended application, the plans show the building sited about one metre from the boundary. Whether deliberate or not, this is an error. Neither the siting of the building nor the line of the site boundary altered between the dates of the two applications. We are unsure whether, or to what extent, the officer who decided this application under the council's scheme of delegated powers appreciated this error. However, as H9 is referred to in the reason for condition 6, it appears that it may have been appreciated. On this basis it appears that the council considered that condition 6 would be sufficient to ensure compliance with the policy. However, that involves placing on the words of the policy a meaning which they cannot reasonably bear because the policy is clearly dealing with the effect of physical height and bulk and proximity to the adjacent boundary not with whether there is floorspace in the upper storey."
"No additional floorspace shall be provided within the building hereby permitted in the form of a single storey side/rear extension without the prior written approval of the local planning authority."
"In order to comply with policy BE1, H8 and H9 of the adopted unitary development plan, to accord with the terms of the application and prevent over development of the site."
"1) Nowhere within the officer's delegation report was it mentioned that the application at Chesham House complied with policy H9. It was considered that policy H9 regarding side space was not relevant as the proposed development was single storey, and policy H9 refers to development of two or more storeys. 2) Condition 6 of the application states that: [the condition is cited]. This condition, along with condition 4 stating that the development must be built in complete accordance with the submitted plans was included in order to prevent that building being used as a two storey development. Policy H9 has stated within the reason for the condition not because the development complies with the policy, but to demonstrate that a two storey development cannot be created in the present location as it would be contrary to policy H9 and would not be likely to be agreed or permitted."
"Policy H8 With respect to policy H8(i) and BE11, the council considers the scale and form of the permitted development is not out of keeping with the host dwelling house, which is a large detached property. Condition 2 has also been imposed, in order to comply with policy BE1, to control the materials of construction, requiring that as far as practicable the materials used match those of the existing building. With respect to policy H8(ii), the council considers the single storey side/rear extension is linked to the main dwelling house, therefore there is no space between the extension and the host dwelling house. A space has been retained between the flank wall of the development in question and the property boundary between Chesham House and Chalvedune [that is the claimant's property]. This was clearly illustrated on the approved plans."
"You confirmed at our meeting that there is no intention to use the roof space at present. However, if at some future date it is proposed to use the first floor to provide additional floorspace, whether for additional living accommodation, storage or any other ancillary use, I confirm that planning permission would be required. Any application would be considered on its merits, having regard to the development plan and any other material considerations, including the impact on the amenities of the adjoining properties."
"On1 February 2008 I visited Chesham House and inspected the inside of the extension. I was able to view the roof space through an inspection hatch. I was able to confirm that a first floor had not been constructed within the building above the ground floor."
"In our view, the time has now come to accept that a mistake of fact giving rise to unfairness is a separate head of challenge in an appeal on a point of law, at least in those statutory contexts where the parties share an interest in co-operating to achieve the correct result. Asylum law is undoubtedly such an area. Without seeking to lay down a precise code, the ordinary requirements for a finding of unfairness are apparent from the above analysis of the Criminal Injuries Compensation Board case."
"First, there must have been a mistake as to an existing fact, including a mistake as to the availability of evidence on a particular matter. Secondly, the fact or evidence must have been 'established', in the sense that it was uncontentious and objectively verifiable. Thirdly, the appellant (or his advisers) must not have been responsible for the mistake. Fourthly, the mistake must have played a material (not necessarily decisive) part in the tribunal's reasoning."
