Howard's solution to the related problems of rural depopulation and the runaway growth of great towns and cities was the creation of a series of small, planned cities that would combine the amenities of urban life with the ready access to nature typical of rural environments. The main features of Howard's scheme were: (1) the purchase of a large area of agricultural land within a ring fence; (2) the planning of a compact town surrounded by a wide rural belt; (3) the accommodation of residents, industry, and agriculture within the town; (4) the limitation of the extent of the town and prevention of encroachment upon the rural belt; and (5) the natural rise in land values to be used for the town's own general welfare.

Howard's ideal garden city would be located on a 6,000-acre tract of land currently used for agriculture purposes only. It would be privately owned by a small group of individuals; this company, in retaining ownership, would retain control of land use. Revenue, to pay off the mortgage and to fund city services, would be raised solely by rents. Private industry would be encouraged to rent and to use space in the town. Only a fraction of the tract's land would be built upon by the town's 30,000 inhabitants; the rest would be used for agricultural and recreational purposes.

At the centre of the city would lay a garden ringed with the civic and cultural complex including the city hall, a concert hall, museum, theatre, library, and hospital. Six broad main avenues would radiate from this centre. Concentric to this urban core would be a park, a combination shopping centre and conservatory, a residential area, and then, at the outer edge, industry. Traffic would move along avenues extending along the radii and concentric boulevards.

Howard stressed that the actual placement and planning of such a town would be governed by its site. In 1903 he had the pleasure of seeing his plan realized. A garden city called Letchworth was developed about 30 miles north of London in Hertfordshire, Eng. It succeeded according to the guidelines that he had laid down, and in 1920 a second, Welwyn Garden City, was established nearby. Howard's concept of interrelating country and city in a planned city of predetermined size has enjoyed wide popularity in the planning of subsequent new towns. His emphasis on greenbelt areas and controlled population densities has become an integral part of suburban and city planning as well.
