Roe Green Park is a park in the London Borough of Brent, northwest London, England. The Barn Hill Conservation Group maintain the Roe Green walled garden that is within the park. This now much used park came about because of the rapid growth of suburban housing in this part of the district in the early 1930s.
 

Kingsbury Manor was purchased by a Mr Cloke a local builder and developer in 1929, and surrounding Valley Farm land the following year. Under pressure from the local Ratepayers' Association, the Council negotiated with Mr Cloke to purchase some of his other land for a park, and in March 1935 two fields on the south side of Bacon Lane (about 21 acres) were bought for about £27,000.
 

The building we now know as Kingsbury Manor was designed by W. West Neve, and built in 1899. Its original name was “The Cottage”, and it was constructed as a country house for the Duchess of Sutherland, in ten acre grounds next to Valley Farm, Kingsbury. Born Mary Caroline Mitchell, daughter of the Principal of an Oxford college, she inherited a large amount of money when the Duke (her second husband) died in 1892, just three years after their marriage.

In the autumn of 1928 the disused coach house (now the Lodge Kingsbury Road) was rented by John Logie Baird, who employed a small team of engineers to work there on his invention, television.
Eighty foot high masts were erected, and the first picture broadcast from the continent was received in 1929, with the first combined transmission of sound and pictures the following year, the concretebase for one of Baird’s TV masts is still there.
