My only concern is, to get from either chamber they'd have to go across an entrance to a garage, are you sure they aren't originally ducted into the garage's?
Normally the engineer will be happy to use a suitable pre installed duct, it after all saves them time and work, but you need to consider how the are going to get the fibre to the external entry point.
A couple of years ago the garage was converted to cinema and the hatch blocked up on my side, however at the time I got OR to update the terrible terminal block in there. It does just look like an armoured cable coming up between the properties, with the armouring taken back 6 inches. There was a thread about it here:
https://forum.kitz.co.uk/index.php/topic,20944.0.htmlEven if they could get in (assuming it is ducted), the route from there into the house would be terrible. The cables come out of the corner of that wall box in the garage, go into the floorspace above, across the width of the house, then twist and turn and come out under the stairs, which is the only place with power at the front of the house.
Maybe they're doing all this work for nowt and were assuming they could come up into the houses. Or perhaps the assumption is they're going to have to come out of these new boxes in the flowerbeds and up the fronts of the properties. Not sure if they'd go across the front of a property above a garage though, which leaves the next option - that they come out of the flowerbeds and lift the paving to get across the garages.
The two boxes in flowerbeds serve 7 houses, and the flowerbeds are only in front of 4 of the properties, so there must be a plan for the other 3 (or maybe not, perhaps we're SOL and not getting it). Lots of my neighbours have done various vors or conversions in their garages so if the plan was to come into the houses between them in the garage, lots of us won't get service.
What is also a bit weird is that all through the various works ongoing the OR availabiity checker keeps changing it's mind. Sometimes it says FTTP coming soon, sometimes not. At the moment if I try to move my FTTC service and do the search for that with an ISP (eg BT, though currently with EE), it returns that FTTC is not available, and only offers ADSL! I guess that might be a symptom of them not wanting to do anything with FTTC given the forthcoming FTTP? I did check and it's not just me. Even the neighbour who's directly in front of the flower bed can now only get ADSL.
