neighbour wants my permission re building garage on fenceline.. Other side already has the same a garage built on the property line so its a bit closed in/hemmed in, as these garages and side walls go much higher than usual fences what problems do you forsee what questions should i ask eg re height depth brick or anything else should i at least get them equal height and length to match but it will be very hemmed in. i measured the side existing with the garage on boundary line goes up almost 3 metres and the roof is heighter so it blocks all my view on that side and i really dont want my view blocked on the other side but do i really have a choice. and is this a big deal or inevitable. its about 8,5 metres long the one there already on the other side, is that a normal size for a garage. i was hoping in future to put a granny flat in my yard with read access to a lane. how would this affect it. will it make it darker having fences much higher on either side of it. how will it affect my property in any way please. it will block a certain amount of sunshine and light from my garden or future granny flat. i beleive it will block a certain amount of view and just feel very hemmed in and make a granny flat darker. its possibly a metre higher than a normal fence line maybe more. is there any reason why its better for me if it was built a bit back from the fenceline how do i know if they need an easement on my block and what this means as i saw a similar question posted years back asking this. it said something about do they need an easement on your block as tahts a great concern having an easement running down both sides of your yard. that some new estates have zero lots and each person has the next door neightbours easement on the non zero lot side I have no idea what this above paragraph means. i dont know what zero lots means or what easements are. it can mean that for any future granny flat i will lose a metre on both sides narrowing my lot and i wont be able to build on the fenceline i will have to have a setback. so i will lose 1 metre on each side of my fenceline how much of a setback would it make me have. so what should i suggest to this neighbour. any other comments about this to consider or ask about please.
