15 We turn first, out of that order, to the view that is enjoyed through the windows in the family/kitchen room. Those windows have a sill, taking into account the frame of the window, some 1,400 mm above the floor of the room. The views through that window towards the respondents' property were entirely views of the bamboo and other vegetation located on the respondents' property and on the property immediately adjacent to and slightly downhill from the respondents' property, fronting Gow Street. That view would be able to be seen, in our assessment, in two fashions. First, as a view of observed in a transitory fashion whilst walking through the room toward the deck area, either in an ingress or egress fashion to that room. Second, if it were enjoyed in a sitting position, it would be, because of the sill height of the windows, a view that was significantly in an upward direction toward the upper part of the vegetation on the neighbouring properties. With the exception of the Lilly Pilly tree and the tops of the palm trees that are presently on the respondents' property and on their neighbouring downhill property that would obscure the view of the sky from a sitting position in that room, we are of the opinion that the view that would be enjoyed from those windows would be a view of the sky and that, from a sitting position, there would be no realistic opportunity of any water views.
16 We are, therefore, satisfied that the view of vegetation from those windows - an otherwise pleasant and green outlook - is not severely impacted by the vegetation that is the subject of the application. We are, therefore, satisfied that there is no jurisdiction with respect to the view from those two windows.
17 The same position does not apply with respect to the views from the two balconies. We were able to observe - as can be seen from the outlook around the corner of the bamboo from the lower balcony or from each edge of the vegetation, that is both the bamboo and the Lilly Pilly tree, from the upper balcony - that the bamboo does provide, from the upper balcony, a reasonably significant and observable interruption to the view and, from the lower balcony, does almost entirely obliterate the view of the water (although, we acknowledge, that there is significant further interruption of possible views to the water occurring as a consequence of the ridge line of the respondents' house).
18 One matter we should observe, at this time, before expressing a conclusion about either of those views is that the respondents' raised the prospect that either they or their neighbour (upon whose property the Lilly Pilly is growing, which is also a property that presently has a single storey house on it, as is the respondents' house) might make applications to the local council for consent to add an additional storey to their dwellings.
19 That is not a matter that we consider relevant in these proceedings, as there was no evidence of any actual application of either nature before us. If there were to be such applications made, they would be dealt with and assessed by the local council in accordance with the relevant Local Environmental Plan and any Development Control Plan provisions and are thus not matters appropriate for us to speculate upon in these proceedings.
20 However, we are satisfied, at least with respect to the view from the lower balcony, which is the principal private outdoor entertaining space adjacent to the living areas of the applicants' house, that the impact on the view from that location is severe and that our jurisdiction is enlivened with respect to it. Whilst the position is marginally different with respect to the view from the upper balcony (as the view from the upper balcony is primarily a view enjoyed from a balcony that is adjacent to bedrooms and certainly not from a primary living space of the dwelling) it is also, perhaps, arguable that that obstruction might be severe.
21 However, as we have determined that the view impact upon the lower balcony is severe and is appropriate for us to consider intervention, it is unnecessary for us to reach a determined conclusion with respect to the impact on the view from the upper balcony (as any remedy that might apply with respect to the view from the lower balcony will also necessarily have a curative effect with respect to the view from the upper balcony).
22 We turn, therefore, to consider matters contained in the Trees Act in s 14E(2)(b) and that is:
"Whether the severity and nature of the obstruction is such that the applicant's interest in having the obstruction removed, remedied or restrained outweighs any other matters that suggests the undesirability of disturbing or interfering with the trees by making an order under this part."
