Lewis (Jack) and Annie (Nance) were still living in the Jones family house at 22 Lowestoft Road, Watford, when their first child, Robert Albert Lewis Jones, was born on 15th July 1921.
In 1922 a radio broadcasting station began transmitting from London with a call sign of "This is 2LO calling", which developed into the first BBC radio service. Lewis became a keen amateur constructor of 'wireless sets', and he was aware of every development in the 1920s. He used designs, such as super-heterodyne, which were published in the amateur wireless magazines. With no mains electricity he used accumulators (batteries) for the 'low tension', which were charged weekly at a local shop, and a box full of 4.5V torch batteries wired together for the 'high tension'. Lewis had a loudspeaker when most people only used earphones. For an aerial Lewis used a square wooden frame with wire wound around it, which was suspended from the ceiling in his bedroom, and gave a better signal than the typical 'long wire down the garden' of most listeners.
North Watford was expanding in the 1920s and they found the new home they wanted. Lewis, Annie and their son Robert moved into 74 Bushey Mill Crescent, Watford in November 1929 and Lewis and Annie would continue to live there all their lives. Their second son, Dennis Eric Jones, was born there on 26
th April 1930. Lewis had rented an allotment garden since 1919, at Harebreaks in Watford, and this was a valuable help supplying almost all the vegetables they needed during the 1920s. He needed a greenhouse, but now could not afford to buy one, so he designed and built his own from rough timber using the tools and carpentry skills that had been passed on to him by his father. Lewis was a keen gardener and there is no doubt some of the flowers he grew were incorporated in his designs. His 'Desert Flowers' chintz in 1938 was probably inspired by his cacti collection. He was constantly searching for ideas and they came from museums, exhibitions and newspapers. When a subject was suggested it was always thoroughly researched.
