In September 1887 a unanimous resolution was carried, "That the mission Work carried on in the cottage at Hawley's Corner now, become, by request of Miss Thorneycroft and the friends worshipping there, a branch of Christian work carried on by Brasted Baptist Church." "The opening meeting was a Harvest Thanksgiving Service held on Wednesday, 12 October, 1887. This was followed by Tea and a Public Meeting when officers were appointed as Secretary, Treasurer and Sunday School Superintendent. Supply preachers served the worshipping community and met with increasing success."

In 1897 the lease on the cottage at Hawley's Corner expired and a new plot of land was purchased next to South Street Farm for £45 and arrangements made to erect a new hall. The new Chapel was opened on 8 October, 1900, free of debt at a cost of £204 15s 9d. In 1910 it became evident that a larger building was required to meet the needs of the growing church. Further strips of land were received as a gift from the owner of the farm, the existing building was moved to rear of the site and became the Schoolroom and a new Chapel was opened for worship on 6 September, 1911, again free from debt at a cost of £314 17s 9d. By 1932 South Street Chapel no longer required the oversight of the Brasted Baptist Church and a special meeting of inauguration was held on 5 December that year attended by the combined congregations of both churches. The first meeting of the newly formed church at South Street Chapel was held on 19 December, 1932.

A lay pastor, appointed in 1942, retired in May 1987. During the Fifties the church experienced a period of rapid growth, especially in its work with children and teenagers and, on 6 June, 1960, a Church Hall was erected to accommodate the greatly enlarged Sunday School (70 on roll) and Youth Work. Numbers later declined with the closing of the local John Grooms Children’s Home and the movement of some members during the late Seventies to the "charismatic" churches. The current lay pastor was inducted in September, 1993, is building upon the solid foundation laid by his predecessors, and the church is again experiencing modest growth.

On all the early maps of the County of Kent, the hamlet now known as Westerham Hill was clearly marked as South Street and as such it was always known until the early 1920s. It formed the south western part of the large parish of Cudham and stretch further north than at present, including the hamlet of Pimlico and Biggin Hill as far north as Lebanon Gardens. Hence, this church was called South Street Baptist Chapel for some sixty or so years from its foundation in 1887. The name was changed for geographical reasons, but to older generations it still remains South Street Chapel - we are a sentimental lot!

The hamlet of South Street was once a thriving agricultural community, some dozen or so farms provided plenty of employment for the local men and also for the women, too, at hay time and harvest. They all knew one another and met regularly at work, the shops, the Post Office, the Pub or the Chapel - a very closely knit rural community, whose livelihood depended on having a good harvest. Which is why this church still places great emphasis on Harvest Thanksgivings.

South Street had three claims to fame. Firstly, its very luscious strawberries - all the farms grew them and sent them to Covent Garden. Secondly, its Racehorses, the stables at Grays Stud Farm, and the range of stables behind the Spinning Wheel (originally called The Paddock - now a restaurant)  were used for Bloodstock and, on at least one occasion, provided a Derby Winner [Silverstead]. Thirdly, its Annual Horse Show was one of the most famous shows in this part of Kent.

Alas! much has now changed. Strawberries are no longer grown here, the Bloodstock have gone long since, there is no Horse Show, the Post Office and shops are all closed, the farms have changed their use and employ little or no labour, the Pub has been revamped and caters for a much wider area and passing trade -  BUT the chapel remains, now called Westerham Hill Baptist Church, and still faithfully proclaiming the Gospel of the Lord Jesus Christ, as it has done for the past 114 years.
