London Festival of Architecture 2016: 60 years after John Leslie Martin completed the Fitzhugh Estate in London, photographer Sharon O'Neill visited to see if the project lived up to its promises (+ slideshow).

The Modernist housing estate in Wandsworth was designed by the late British architect as a blueprint for the future of housing in line with the "new social agenda", as laid out in his 1930s publication The Flat Book.

Today, it offers an insight into whether post-war housing meets the needs of the 21st-century family, and whether the ideals of architects like Martin are worth revisiting.

On show as part of a London Festival of Architecture entitled Blueprint for Living, O'Neill's photographic series Flats offers a look inside some of the homes in the estate. In this essay, presented alongside archive photography, she describes her intentions.

The Flats series is a photographic exploration of one architect's vision of the "modern world" as told through the lives of the current inhabitants of one of his buildings.

Through a mixture of archive material and contemporary photographs, the series delves into the everyday world of the occupants of a council block designed and constructed in the mid-20th century.

The work attempts to frame the young architect's principles of Modernism from the perspective of his idealistic vision of the 1930s. Using the building and interiors of the current inhabitants, it develops a photographic dialogue to illustrate his "modern world", in essence, the realised future of his 1930s vision.

In 1939, the architect John Leslie Martin and his wife, Sadie Speight, published The Flat Book, which outlined their principles of design when living in the modern apartment. The introduction discusses the close relationship between planning and furnishing: "furnishings … are affected in their design, like architecture itself, by similar radical changes in methods of production, changing social requirements and by the contemporary demand for convenience and efficiency. It is in these basic conditions that all style has its roots."

The book – essentially a catalogue of furniture, fixtures and fittings – offered ideas and suggestions on planning the living space. It touched on new developments in the design of the flat, like giving less space to kitchens and bathrooms to provide a larger general living area.

In 1937, Naum Gabo, the Russian sculptor and painter, Ben Nicholson, the British abstract artist, and Martin edited Circle: International Survey of Constructive Art, a book which aimed to highlight the British contribution to the European abstract movement and brought together their shared ideology that Constructive art, architecture and design would improve people's lives. The book included contributions from Piet Mondrian, Le Corbusier, Laszlo Moholy-Nagy, Barbara Hepworth and Walter Gropius among others.

In Circle, Martin wrote eloquently about the machine age and the idea that art, design, architecture and society were not separate entities, but were all elements of the same conversation.

Martin was one of a group of architects who truly believed a better society could exist where social problems could be solved through intelligent design based on the scientific approach of identifying the problem, research and analysis.

In 1953, work began on what was to be known as the Fitzhugh Estate, a collection of five point-block buildings set on the edges of Wandsworth Common and designed by Martin. Commissioned as part of the massive post-war building programme, the aim was to alleviate the desperate housing shortage. This was in part due to bomb damage, but also as a wider initiative by the post-war government to provide decent, healthy homes for low-income working-class families.

The architect and historian John McKean poignantly describes the mood in post-war Britain at this time: "The new social agenda centred on the concept of 'fair shares': the people's war was to be succeeded by the people's peace; its achievement would be seen in the national health and educational services and in popular housing for all."

Widely viewed as a significant period for British Modernist architecture, Modernism was embraced by the civic architects who were handed the task of rebuilding post-war Britain. The jewel in the crown was the Royal Festival Hall, designed by Martin in 1948 whilst at the London County Council Architects Department. The building is widely regarded as one of the masterpieces of post-war British architecture and Martin received a knighthood in recognition.

The LCC Architects department in this post-war period gained much admiration as the largest architecture practice in the world and with the brightest of British talent. Martin was deputy and then head of the department at this time.

Architects like Martin were celebrated in the exhibition A Place to Call Home at the Royal Institute of British Architects, where their role was highlighted as "crucial in framing a modern view of the world … they provided new and idealistic plans for housing and blueprints for living".

The Fitzhugh Estate in Wandsworth, London, was part of this blueprint. Martin and his team designed state-of-the-art social housing that was featured in The Architects' Journal in November 1956, written as the first residents moved in. The building was lauded for its cutting-edge technology – using precast concrete and a 300-foot tower crane to speed construction – and full central heating.

Originally the flats were built to provide homes for local working-class families, and were serviced by communal facilities to improve health, hygiene and provide a good quality of life.

Since their construction 60 years ago, the concept of the council estate has undergone a huge shift. Originally perceived as a "step up", since 1980, when the dismantling of the council housing system began, it is more generally regarded as undesirable.

The block in Wandsworth is currently populated by a mixture of council tenants, those who purchased their flat through the Right to Buy Scheme and professionals who have bought properties on the open market either to live in or rent out. Demonstrating a significant shift from the original demographic.

This series is an exploration of how the idyll of a young architect has stood the test of time as society has changed and how his ideas of design for the living space, as demonstrated in The Flat Book, may have permeated into the modern sensibility.

The work acts as an interpretation of Martin's blueprint for living, a visual letter from the future back to the young architect of 1939.
