Doubleday's father was a grocer and following his death Doubleday managed the business, not very well, apparently. This Facebook page has a 1975 photo of the building with the plaque, 271 High Street, when it was the grocers 'International Stores'. That page also has this 1966 photo of the previous building being demolished. It was clearly a shop but one can't tell what it sold. Note the building to the left, south, could easily date from 1800. So it seems a fair assumption that this is the building in which Henry Doubleday was born in 1808 and died in 1875.
