The residue of Cockman's Farm became Woodfield House, home to the Roman Catholic Passioist Fathers (1852 and 1858).

In 1896 Schweppes opened a large mineral water factory, and the present Anglican church of St. John's was established in Algernon Road.

With a planned tram line along the West Hendon Broadway due to open in 1904 and run by Metropolitan Electric Tramways, Welsh Harp station was closed in 1903, and West Hendon became a thriving Edwardian retail district[2] until overshadowed by Golders Green.

During World War II, on 13 February 1941, the Luftwaffe dropped a single SC2500 maximum heavy explosive bomb (equivalent to two V2 rockets), killing 85 people, injuring hundreds, destroying 40 houses in an area west of the Edgware Road and making over one thousand locals homeless.

[4] During a very hot summer in the 1960s, the water levels fell dramatically and remains of some of the destroyed houses could be seen.

[5] In 1984 a small Islamic Centre was established at 135 the Broadway; it was later moved to Brent View Road and reopened as Hendon Mosque on 23 August 1996.

[2] Hendon Mosque notably held the funeral for Nazia Hassan, a pioneer of Pakistani pop music, in 2001.

110 West Hendon Broadway was built in the 1930s as an attractive building with a floral clock in its front garden.

Originally used for a local car parts business, the building was seemingly used as UK headquarters for the Free German Trade Union Federation from the 1970s to 1990.

[12] The most prominent building of the new development is Hawfinch House, a high rise 26 storey tower that is 85 metres (279 ft) tall, completed in July 2016.

[15] Barnet London Borough Council has faced criticism for its regeneration of the West Hendon Estate, including the use of compulsory purchase.

[1] In 2018, Jeremy Corbyn and Mayor Sadiq Khan visited residents in the estate and were told of having been let down by Barnet council.

[17] The estate has been featured on the BBC's Victoria Derbyshire show, which found that the Marsh Drive block was in poor condition.

The Silk Stream, a tributary of the River Brent, marks its northern boundary with The Hyde, a small loose area bordering Kingsbury and Colindale.

The Silk Bridge on the A5 crosses the stream to the Hyde, across which is a retail park, a Sainsbury's supermarket and Hendon Magistrates' Court.

In addition, Cool Oak Lane forms part of the designated London Cycle Network.

The street contains several local amenities such as a post office, surgery, restaurants and an Irish pub (The Wee Pub, formerly O'Hanlons), beauty salons and hairdressers, and other businesses and organisations including the Welsh Harp Boat Centre and its accompanying cafe.
