The Greeks of the Community were distinguished for their industry and their business acumen, and, being economical and frugal, especially during the early years of their establishment in London, soon became for the most part financially independent.
They now wished to enjoy a more comfortable life, both for themselves and their families. They kept their offices in the City, but took up their private residences in other parts of London.
The favourite districts were Lancaster Gate and Bayswater.
These districts, which today are almost in the centre of the unending metropolis , were then only on its fringe, and to go from the City to Hyde Park, for instance, was considered a long excursion, which was undertaken, normally, only on holidays, as a relaxation and in order to enjoy the fresh country air.
After three decades had passed from the founding of the Church of Our Saviour, no one any longer had his private residence in the City; and whereas previously all had lived within a very short distance of the Church, now five whole miles divided the Church from the residential district of the faithful.
For the men, in particular, who had every day to make the journey to the City, a tiring one with the means of transport then available, it was hard to undergo the same fatigue on Sundays also, when they were supposed not only to perform their religious duties, but also to rest from the labours of the week. Moreover, the number of the Greeks had greatly increased, and there was scarcely room for them all in the Church then existing. These various difficulties made it imperatively necessary to build a new larger Church, situated closer to the residences of the Brothers.
When agreement had been reached on the questions of the site and of the method of erecting the Church, the General Meeting of the Community on January 31, 1874, elected a Building Committee, with Emmanuel Mavrogoreato as Chairman and the following members: D. Vikelas, C. A. Ionides, S. Constantinides, P. P. Rodocanachi, P. Sechiari and D. S. Schilizzi. At the same time the Community elected another committee, for questions of finance, composed of A. A. Ralli, M. E. Rodocanachi, M. Paspati and S. Dilberoglou. The secretary of this committee was S. Papantonopoulos.
After the Building Committee had received instructions from the General Assembly they did not seek to begin their work humiedly. They were inspired by the noble ambition to give those who had elected them not just any kind of Church, not 'some shabby building', as they said, able somehow or other to serve the religious needs of the ever-increasing Greek colony in London, but a beautiful Church, outstanding in style and execution, a monument worthy of the great names of the Greeks settled in London and of the Greek Orthodox Church.
In their preliminary labours, as also after the work began the committee had the advantage of the professional assistance of Messrs. Freshfield and Williams, who advised them on legal questions which arose from time to time, and of the architect of the Church, John Oldrid Scott, son of the famous architect Sir George Gilbert Scott, and uncle of the Scott who designed and supervised the construction of the Anglican Cathedral at Liverpool. The contractors for the building were Messrs. Kirk and Randall.
In order to ensure that the execution should conform to the plans and that expenditure should not exceed the estimate, the committee proceeded to make an exact preliminary study of every part of the building and of every particular of the design, from the great dome down to the smallest door.
The quantities, measurements, materials and complete design were set out in detail. The plans amounted in number to 600.
After the Building Committee had laid these firm foundations for the work and had precluded all unnecessary expense, and after the financial committee had collected the contributions of the members of the Community, the work began.
In the month of June 1877 the foundations of the Church were marked out, and on July 18 of the same year the foundation-stone was laid. The learned patriot Mr. Emmanuel Mavrogordato delivered a speech appropriate to the occasion.
