Postcode district: HA3
The postcode district HA3 is based on a north-west to south-east axis. Its northern boundary goes approximately from Harrow Weald Common, down Brooks Hill and along Kenton Lane, until its junction with Kenton Road. Here the boundary moves slightly to the east, to follow Fryent way, Salmon Street, Forty Lane and then Forty Avenue. After curving around to use Eastern Lane as its southern boundary, HA3 uses the train tracks linking North Wembley, South Kenton, Kenton and Harrow and Wealdstone tube stations as its western boundary. The northern boundary follows Uxbridge Road as it crosses the train tracks, and then follows Oxhey Lane to meet with Harrow Weald Common. HA3 includes the areas of Harrow Weald, Wealdstone and Kenton.The HA3 postcode district lies within or includes part of the following towns, counties, localities, electoral wards and stations: Barnhill, Belmont, Brent, Greenhill, Harrow, Harrow & Wealdstone Station, Harrow Weald, Hatch End, Kenton, Kenton East, Kenton Station, Kenton West, Marlborough, Northwick Park, Northwick Park Station, Preston Road Station, Queensbury, Wealdstone.
Records that date as far back as the thirteenth century describe Kenton, or as it was then known, Keninton, as a hamlet, which we now know was concentrated around Woodgrange Avenue. However, the area grew, in the same way as so many of the London suburbs grew, following the opening of the railway. Harrow and Wealdstone station opened in 1837. At that point the area was almost entirely rural. Harrow-on-the-Hill was more developed and was the closest settlement of any size, though was 1.5 miles away. By 1908, however, the population had grown enough to warrant the opening of Preston Road tube. This was quickly followed by Kenton Station which opened in 1912, and South Kenton station which opened in 1933.
Bellfield Avenue, Brookshill Drive and West Drive, all in the very north of the postcode district, are some of the most expensive streets in the area, where four or five bed family homes can reach six-figure asking prices. Not only are the properties themselves substantial, the location is ideal, allowing easy access to the motorway, using the Uxbridge Road as a link to the city and the nearby open spaces of Pinner Park and Harrow Weald Common. The area also benefits from a number of golf courses. At the more southerly end of the postcode district, there are some similarly desirable family homes, such as those on Northwick Circle. Due to their proximity to the underground station, these four bed detached properties can often reach asking prices of £850,000. Aston Avenue near Kenton tube station also has desirable properties for around £700,000, whilst Elmwood Avenue (running parallel to the train tracks) also has some desirable properties with asking prices of approximately £750,000.This shows that the most desirable areas within the postcode district, which contain the most substantial properties, are those at the very north or the very south. In the middle of HA3, however, there is some more affordable property. The most affordable areas appear to be on the east side of the High Road that links Harrow Weald and Wealdstone, particularly around College Road, Spencer Road and College Avenue, where there is a mix of both purpose built blocks and period conversions.
