Sunray Avenue

Sunray Avenue preserves the form and character of a 1920s garden suburb. The street runs through a carefully planned estate of tile-hung cottages and short terraces, arranged around wide verges planted with mature trees and generous communal green spaces. Unlike the dense Victorian terraces that dominate much of south London, Sunray Avenue reflects an aspirational moment when postwar housing policy embraced open air, light, and the garden city ideal.

The buildings retain many original details—curved tile work on chimneys, timber picket fencing, and broad bay windows. What makes this avenue distinctive is not the individual houses but their collective arrangement: a planned landscape rather than incremental street growth. The Dulwich Estate controlled the design, and this shows in the estate’s spatial cohesion and its preservation of trees. That cohesion comes from a deliberate choice to name the place after something beautiful.

The estate lies on the south slopes of Herne Hill, which is one of the most celebrated estates of the ‘Homes for Heroes’ campaign following WWI. By 1920 Casina was empty and the Dulwich Estate released the land to Camberwell Borough Council for much needed social housing. A clause in the plans enabled an area of open space to be preserved for recreational purposes and the area around the lake was chosen and laid out, initially called Casino Open Space, renamed Sunray Gardens in 1923. The street itself derives its name from this garden space—Sunray Gardens—which in turn took its name from the newly opened park. The name “Sunray” carried symbolic weight: it evoked brightness and renewal after the devastation of the First World War.

The word “ray” dates to the early modern period, while “sunray” as a poetic compound became established in the nineteenth century. The choice to name a public garden “Sunray” rather than retain “Casino” reflected the values of the age—an emphasis on light, hope, and the democratization of leisure, not gambling or aristocratic pleasure. The street inherited this hopeful nomenclature.

Sunray Gardens is a remnant of the landscaped grounds of Casina, a late eighteenth-century house on the Dulwich Estate. The grounds were designed by Humphry Repton, including a large lake that survives as the sole remnant from the earlier landscape. Casina was built by the architect John Nash in 1796 for Richard Shawe, a lawyer to Warren Hastings. Other residents of the Casina estate included Joseph Buonaparte, Napoleon’s brother, and from 1875 it was the home of William Stone, MP for Portsmouth, a garden enthusiast who allowed the Surrey Horticultural Society Flower Show to take place in the grounds.

The estate developed after 1920 as one of London’s earliest “Homes for Heroes” schemes, built to house returning soldiers from World War I. Woodland Way, Sunray Avenue and Vincent Avenue were nearing completion by the end of 1935. The estate was laid out using “garden suburb” principles which involved a planned layout around generous green spaces. Unlike the traditional Victorian street terraces, this estate embodied new thinking about working-class housing: light, air, and communal greenery rather than density and profit.

The Friends of Sunray Gardens was formed in 1997 to preserve the park and Sunray Gardens was refurbished in 2001. Today the pond from Repton’s original design remains, ducks still visit, and the mature trees frame the estate—a rare survival from the Georgian landscape beneath layers of twentieth-century housing.

Sunray Avenue embodies the “garden suburb” aesthetic that emerged in early twentieth-century Britain, inspired by Ebenezer Howard’s ideas about planned, humane communities. The Sunray Estate was one of the first municipal applications of these principles after the First World War. Unlike later estates built with economy in mind, Sunray retained qualities that earned it recognition as a distinctly planned community: the coherence of design, the survival of front boundaries and hedges, the proportion of space to building.

The estate preserves the lake from Humphry Repton’s original landscape design for Casina (c. 1796). This remnant, now within Sunray Gardens, is one of the most direct continuities between the Georgian estate and the postwar suburb. The water feature anchors the public realm and connects residents to a history most will never know.

The estate was designed for returning soldiers and their families, but the historical record on individual residents is sparse. The gardens and park, rather than the street itself, are more extensively documented. Two notable figures connected to the broader SE24 postcode area bear mention: Richard Church (1893–1972), writer and poet, lived here as a teenager and went to school locally. He published his first poem in 1917 and wrote no less than 16 novels and three volumes of autobiography over a career which spanned more than 50 years. Church’s presence in Herne Hill during his formative years places him near the Sunray Estate during its construction period.

The estate itself commemorates the many unknown soldiers for whom it was built. No single figure dominates the street’s narrative; instead, Sunray Avenue represents a collective endeavour to provide decent housing to those who had served. The street’s name memorializes not a person but an ideal: the brightness and renewal promised to a generation returning from war.

The Sunray Estate has undergone selective modernization over the decades while retaining its essential character. The late twentieth century saw pressure on the original green boundaries as residents added driveways and removed front walls for parking. Yet amazingly the hedges have survived and the front gardens have not been lost to parking to a notable degree, particularly on Sunray Avenue itself. Many householders have chosen to respect the original planning philosophy, retaining verges and trees even as adjacent areas intensified.

The refurbishment of Sunray Gardens in 2001 marked a renewed commitment to the public realm. The Friends of Sunray Gardens, established in 1997, has stewarded the park and its historic lake. The street remains sought-after by families drawn to its garden-suburb character and its trees, and property values reflect the estate’s enduring appeal. In a borough increasingly defined by modernist housing and urban intensification, Sunray Avenue preserves a quieter, more spacious vision of London living.

Sunray Avenue today is a quiet residential street in the North Dulwich Triangle, one of south London’s most desirable neighbourhoods. Victorian conversion flats and family homes dominate the postcode, but Sunray Avenue itself remains defined by the 1920s–30s cottage terraces and the broad treatment of street space. The proximity to North Dulwich railway station (roughly 10–15 minutes’ walk) has made the area accessible to commuters, yet the estate’s design insulates it from traffic: there is no through-route to neighbouring areas, a deliberate planning choice that preserves tranquility.

Sunray Gardens, the public park from which the street takes its name, remains a focal point. The lake at its heart draws families and wildlife. Mature oaks, chestnuts, and other trees planted in the 1920s–30s are now over a century old and define the quarter’s character. The street itself is lined with these trees, and residents and visitors continue to value the spaciousness and greenery that the Camberwell Borough Council and the Dulwich Estate agreed to preserve over a century ago.
