Renovation / Extension - Fireproof glass, potential options?

[boxrick]

Hello folks! I am planning a home renovation / extension. I will be completely gutting my property internally and extending.

 

My new architect tells me I need fire rated windows due to its vicinity to the boundary. I have included pictures and circled in red the bit which is causing an issue along with pictures of the border. But as you can see my windows are fairly large and likely going to have to be custom, I don't even believe I can get something like this fire rated because of the difficult shape.

 

On the other side of the boundary is a golf course and a bunch of trees and weeds ( basically nothing ). I am currently trying to purchase the land on the other side of the boundary to give me enough space and have made attempts to get fireproof glass / frames without much luck. 

 

Is what my architect tells me completely correct?
Is there any sensible ways to work around this, or does anyone have any suggestions?
Does anyone know somewhere which may do the required fireproof windows ( frames / glass as a unit )?

what is the distance to the boundary?

Seems to be a lot of mature trees very close to where you proposing to build, and you will be digging well within the root protection areas. If they are not on your land, how are you going to deal with this?
