18 I am satisfied that a comparison between the development, as currently approved, and the development as proposed to be modified will be "essentially or materially"" the same as the approved development for a number of reasons. These are:
+ the proposed use does not change,
+ the external building envelope and volume is identical to the original approval,
+ the internal configuration is identical to the original approval,
+ the walls to be replaced have no special significance,
+ the new walls are generally in the same location as those demolished,
+ the safety and structural reasons for the removal of the walls was not challenged,
+ there was no suggestion that the retention of the walls was a fundamental consideration of the development application and that a different decision would have been reached if the walls were always proposed to be removed, and
+ the new walls do not impose any additional amenity impacts on adjoining properties.
19 In Thomas, consent was granted for alterations and additions an existing dwelling however the whole of the main part of the house was demolished including the floor and internal walls that were shown to be retained on the approval. Clearly, the demolition of the parts of this dwelling shown on the approval to be retained were more extensive than in this case. Moto Projects requires a qualitative and qualitative assessment in any comparison between the development, as currently approved, and the development as proposed to be modified. In my view, the circumstances in Thomas can be clearly distinguished from the circumstances in this case, particularly considering those matters in par 18.
