An important feature of the design was the suspended cross with its two shadows. It was made by Mr. Mitchell, the woodwork teacher of Craybourne school, using pine from surplus pews. After being stored in St Mary Cray Parish Church it was carried in procession to Sidcup by the Youth Club on Good Friday.
Mr. Mitchell and his boys also made the Communion Table, from individually jointed strips of pine, one for each church member. No glue was used in the construction. It symbolises both a table covered by a cloth and a carpenters bench.
Regular united services were held in the two churches during the Second World War and they continued afterwards on an occasional basis.
In the 1960s and 70s there were moves towards Christian unity. In 1971 a 95% majority of members supported union of the Congregational and Presbyterian Churches to form the United Reformed Church. The proposed merger between the URC and the Anglican Church however failed to materialise. Between 1973 and 1975 discussions between the URC and Methodist Churches eventually led to a 75% majority of both churches in favour of combining. For financial and practical reasons the Methodist building was chosen. The first meeting of the combined church actually took place in the Station Road church because of roof repairs at Hadlow Road. On March 24th, following a ballot, the name Emmanuel was chosen. The Station Road church was eventually leased to the Barnabas Fellowship, now the Sidcup Community Church.
In 1990 the Church Hall was extended by the addition of the Green Room with a capacity of 50 people. A storage hut for the Scouts and Guides was also built behind the church. In 2007 toilets for the disabled were constructed in the church and the hall.
To celebrate the Millennium, in 2000 a full set of pew runners and chair cushions were made by members of the congregation.
In 2008, a complete re-wire of the Church and improvements to the wiring of the Hall were completed.
In 2016 a major refurbishment of the church hall was undertaken with updated heating, repainting and floor sanding.
