MR JUSTICE WAKSMAN:
"Though the properties are connected by retaining a single storey, the infills maintain the sense of space and visual separation between the properties. It is very characteristic of the area."
"The gap is significantly eroding resulting in the terrace appearing to merge into the application property to the detriment of the open character conservation area."
"At 7 to 11 the terrace is constructed of stop brick while the host property is fully stuccoed. The use of perforated metal cladding will introduce a wholly new material into a prominent and important frontage that does not compliment or reflect the existing appearance. The perforated metal will appear as an incongruous and alien feature."
"The terrace would be located one to two metres away from our client's bedroom and, secondly, it would directly abut the side wall of our client's house."
"We are willing to discuss whether the metal frame for the terrace needs to be attached to our neighbour's end wall or whether it could be made lighter."
"The terrace is utilised in the evening when the clients are open, very short distances will mean that any voice means that comings and goings will be readily audible."
"Secondly, the terrace would itself physically adjoin the side wall. No details are provided, but it may be that the case there will be some form of structural connection physically tying into to the wall. It raises the concern there will be noise and vibration transference through the wall as a result of footsteps on the terrace, general moving, scraping of chairs et cetera. The wall was not designed to insulate against such noise impacts and it is an end of terrace property.
The application has provided no assessment of the impact of noise and disturbance or proposed any acoustic treatment and this runs contrary to policy DM31."
"The second objection expressed concern for potential noise disturbance due to proximity of roof terrace to adjoining bedroom windows. The letter also states the roof terrace and staircase would result in overlooking reducing the level of privacy enjoyed in a neighbouring garden. Furthermore, the letter states that the side extension would reduce sun light to neighbouring gardens.
The letter also objects to visual impact on the side extension due to the loss of visual separation between the adjoining terrace on Dartmouth Row and the application property eroding the open character of the conservation area. In addition, the letter states a side extension introduces a new material to prominent frontage, contrasting significantly with the stucco of the application property and the brick of the adjoining terrace forming an incongruous addition to the Street."
"The following policies are considered to be relevant to this application: DM1, 30, 31 and 36."
"Side extension of terrace is said to be considered to be a later extension to the property. If replacement is considered acceptable, the proposed side extension will be relatively modest, proportionately subservient. Officers consider the contrasting material and canted frontage will prevent a terracing effect helping to maintain the sense of visual separation. The retention of the large gap at roof level further enhances the separation. The extension successfully responds to the surrounding architecture, particularly the canted frontage which references various elements of the host building. Furthermore, the reddish colour references the tone of bricks on properties on the western side of Dartmouth Row opposite the application property. Both the terrace and the French doors would be screened. That is because of the structure at the front."
"The roof terrace is not considered to give rise to unacceptable noise disturbances given that the side elevation does not have windows. The terrace is considered to be a sufficient distance from the windows in the rear and front elevations of number 11. It is also considered that an element of external noise would be expected within an urban residential environment such as this."
"It does not give rise to unacceptable noise disturbances, given that the side elevation does not have windows. The terrace is considered to be a sufficient distance from the windows in the rear and front elevations of number 11 and you would consider that that element of external noise would be expected in an urban environment anyway."
"I confirm I took potential noise impact of the proposed roof terrace into account. I did not request the applicant to submit any formal noise assessment. I did not consider that one was required."
"It is not clear whether the extension was to be attached."
"Even if it was constructed in such a way, vibration would not be a material planning consideration for this type of development."
"To avoid structural transmission between the two properties the avoidance of physical contact between the dividing wall and the new proposed structure would generally rule out the appearance of adverse effects. Conceptually, a metal structure fixed directly without a resilient and anti-vibration product onto a party wall has the potential of transmitting structural noise in the new structure and its connected elements and through to the dividing wall. This could then become a new source of reradiated structural noise not previously present at 11 Dartmouth Row.
Typical uses of the new terrace which would have the potential to transmit structural noise are walking on the terrace or stairs, trailing or dropping objects and, depending on the type of structural connection, banging of doors. All of these are considered to be reasonable use of the space. If the new proposed structure were connected without the anti-vibration products, the noise transmitted via the structure of the adjoining residence would have the potential for being noticeable and not intrusive or potentially noticeable and intrusive during the daytime based on the definitions in PPGN."
"The implications would be that small changes would imply, for example, turning up the volume of a TV set next door defined as an adverse effect during the night-time. The same type of noise would be notable and intrusive and potentially noticeable and disruptive. It can affect sleep. There is potential for this type of sound transmission to qualify as a significant adverse effect, which according to the guidance in a worst case scenario should be avoided and there could be the possibility of sleep disturbance.
However, it is best practice to isolate finished floors from adjacent residential properties vertically and horizontally. There is no clear requirement to address the lateral transmission of impact sounds. In building regulations it is generally accepted any flooring will be resiliently separated from the structure. It is therefore reasonable to assume the applicant would adopt best practice to minimise the effect of the transmission into the structurally connected adjacent properties.
In summary, if the applicant had no rights on the dividing wall, the construction of an independent structure is unlikely to create adverse effect. If the applicant has the right to access the dividing wall to build the proposed side extension, use of best practice would likely mitigate. Therefore, the intrusiveness of the noise would be reduced in relation to a scenario where best construction practice was not applied."
"The council will protect the local distinctiveness of the borough by sustaining and enhancing the significance of non-designated heritage assets. Development proposals should be accompanied by a heritage statement proportionate for significance of the asset. The council will seek to retain and enhance locally listed buildings and structures and may use its power to protect their character, significance and contribution made by their setting where appropriate."
"A new development or alterations to existing buildings. You should not grant planning permission where it is incompatible with the special characteristics of the area, its building spaces, settings and plot coverage, stale form and material."
