Others have more detailed knowledge than I do of the history, but I suspect that your development is old enough to have received some consideration both in the Openreach commercial rollout and in any state aided project.
Unfortunately decisions have to be made about what is enabled and what isn't. I'm aware of similar oases elsewhere - Bedford cabinet 120 is an example (postcode MK42 9EX is close). Borough Hall is just up the road, the hospital is immediately opposite, whilst the areas on the Kempston side and around the railway depot across the river are residential. Unfortunately, the cabinet is on Palgrave Road a few metres off Kempston Road (on your left as enter the development), a fair way from the flats in Britannia House and Wheelwright House that make up the majority of the addresses. From an FTTC point of view, it would be better in between Wheelwright House and Britannia House.
For a long time Bedford cabinet 120 was slated for the end of the commercial rollout, but appears to have been dropped, possibly because the distances from the cabinet mean those living in the flats wouldn't get a huge speed increase over ADSL. It has never been part of the BDUK plans, so far as I know.
Unless anyone knows any different, there are now no plans to bring FTTC or FTTP to SMBD cabinet 120.
If you are fortunate enough to have enabled properties across the street, one option might be to get a co-operative person nearby in the enabled area to allow you to install and operate a second line there (outgoing calls barred) at your expense so that you can enjoy FTTC via a point to point wireless link, paying a few tens of pounds (or beers) annually for the electricity used to run the equipment. It's not ideal, but might be better than what you have.
