The following historical info was written on a website http://www.yorkroadchristians.contactbox.co.uk/ which no longer exists but can be found on the Internet Archive .. I hope the writer of it will not mind me using it here!
One point that can be added is that W.M.S. took this room consequent on him and others withdrawing from the present meeting at T.W. as the meeting was going with F.E. Raven in the division in 1890.
The building at 41 York road was built sometime shortly after 1867. It is now a Grade II listed building.
The initial use of the premises has become somewhat unclear over the passage of time, although one thought is that it was once a billiard room connected with the property opposite. It is also understood to have been used as an artist's studio.
A Change of Emphasis
The building then came into use as a church around 1890, when it was purchased by William Masters Sibthorpe for the use of some Christians who had been meeting elsewhere in the town. William Sibthorpe was the proprietor of the then well-known Tunbridge Wells haberdashery store W M Sibthorpe & Sons.
W M Sibthorpe’s son, W E Sibthorpe, arranged lunch-time Bible Studies for men in the period leading up to the Second World War.
During the war, an air-shelter was constructed in the basement for use by the congregation during air-raids. This air-shelter is still accessible (though not in use!) today.
There was an active Sunday School around this time (both at York Road and at the associated Grange Hall in Rusthall), which was later run by Douglas Hunniset, who was a draper from Southborough.
More Recent Developments
The building remained in the Sibthorpe family until 1976 when it was purchased by the newly formed York Road Christian Mission, a Charitable Trust created to maintain the building for the use of the congregation and for Sunday Schools. In the past five years, the roof has been extensively repaired and refitted and the exterior has been completely repainted. The interior, however, still requires much work to be done
