Lissenden Gardens was built between 1898 and 1906 by the Armstrong family. Alfred Armstrong was the son-in-law of E. J. Cave, a prolific speculative builder. Alfred had made his fortune first through selling automatic vending machines, then through generating electricity. He was the first to generate electricity in Hampstead. The estate was designed by Boehmer and Gibbs, the architects who were experienced in building middle class blocks of flats in the Hampstead area and working for Cave. Edward Boehmer was American born but had trained in Germany. The estate consists of Clevedon Mansions, Lissenden Mansions, and Parliament Hill Mansions built round what was initially a garden but is now a private tennis court. The flats were built in the fashionable Edwardian period Arts and Crafts style, using red brick, with attention to detail such as stained glass above the front doors and some windows aw well as in the stair columns; hand-made tapered brick arches over the windows; hand-made red clay tiles; and terracotta foliage panels and flower tiles by the front doors. Wrought iron was used for the railings and weather vanes and cast iron in the fireplaces. There were service lifts to raise coal to the upper floors, a speaking tube with a whistle to allow the residents to attract the attention and then to speak to porters, and rubbish chutes from kitchens to ground floor collection bins.
The estate was hit by incendiary bombs in early September 1940 but there were no injuries. On 26 September 1940, a high explosive bomb hit the southern end of Parliament Hill Mansions, destroying 10 apartments served by one staircase. 13 people were killed, including several children. After the war, the remains of 1-10 Parliament Hill Mansions was replaced by the six-storey Chester Court, built in the utilitarian style by architects Anderson, Forster and Wilcox. The Armstrong family's intention was that residents would be able to move into this block, which has a lift, in old age.
In 1972 the Armstrong family decided to sell the estate through a sealed bid auction. The residents formed a tenants’ association and planned an expert campaign to save the estate. This was a period when many estates were being sold and tenants being persuaded to leave, so that new owners could refurbish them and then sell them to owner occupiers, making a significant profit. The Lissenden Gardens Tenants Association lost the battle to prevent the Armstrongs from selling privately, in spite of devising the Lissenden Formula, a creative proposal for the Camden Council to buy the estate, but to then allow tenants to buy the leases to their flats. The estate was purchased by Gulindell. Their first act was to put up the rents. The Gulindell plan was thwarted by the tenants' association campaign. The Council prepared plans to serve a compulsory purchase order on the Gardens, and the tenants' association used this fact to dissuade potential purchasers of vacant flats with posters in windows, warning "‘Caveat emptor’ – buyer beware – the estate was the subject of a compulsory purchase order". Central government refused to approve the compulsory purchase in July 1973, but the council retaliated the same month by serving “dangerous structure” notices on the some of the blocks, requiring the owners to carry out urgent repairs. No flats had been sold and an economic crisis was looming. The council persuaded Gulindell to sell. On 6 October 1973 council leader Frank Dobson, announced that Camden Council had bought the estate for £2.8 million. Residents continued to be organised and active after the sale to the council. They successfully resisted a comprehensive modernisation that would have destroyed the community, by moving all residents out for a number of years, and changed the appearance of the estate. Instead a much more sensitive programme of work was carried out, managed jointly by the council and residents. Lissenden Gardens today is a diverse community made up of council tenants, owner occupiers and private renters.
