Have you access to the deeds of your house - that would show when it was built.
Is it on the 1939 register? Or is that the one that only goes up to number 20.
I do have the deeds but its written really oddly, i dont understand a majority of it. I will go through them again and see what i can find. I found the 20 houses on Find My past. My house is 30 Althorpe Crescent in Milton keynes but i searched under the district of Wolverton or stantonbury. I believe years ago the estate was Bradwell but was changed to Bradville (Bradwell is still around, its not an estate near mine)
