Northam radar station, which operated between 1941 and 1944, is listed at Grade II for the following principal reasons:
* Degree of survival: as a substantially intact Chain Home radar station which retains its principal buildings, tower and mast bases, and other related structures; which allow a clear understanding of how the site functioned;
* Historic interest: as a physical manifestation of tensions and fears during the Second World War, which resulted in the establishment of a chain of radar stations to protect Britain’s coast;
* Group value: for its strong visual and spatial relationship with two associated decoy targets (recommended for scheduling).

The former RAF Chain Home station had the best preserved radar remains in Devon. Chain Home stations developed in stages from, in some cases a mobile unit, through an intermediate station, then the final station. The photograph shows a structure which dates from the intermediate period. Other details: Photograph.

A Second World War Chain Home Radar Station transmitter or receiver block is visible on aerial photographs of 1941 onwards at RAF Northam Radar Station. It appears possibly newly built on aerial photographs of 1941, and surrounded, but not covered over, by protective earthworks on aerial photographs of 1945 to 1958. It might be an Intermediate Chain Home (ICH) building, a midway stage in the development of Chain Home stations with permanent towers and temporary buildings. By 1958 the roof of the structure had been removed or collapsed. Several outbuildings can be seen in the immediate area, probably associated with the blockhouse. Two of these survived as structures in 2007, the location of a third immediately to the south of the blockhouse is visible only as foundations, whilst a fourth and fifth structure, at circa SS44802998 and SS44812993, appear to have been completely removed. The precise function of each outbuilding is uncertain but the radar station would have contained a stand-by generator, a sub-station, air-raid shelters and guard houses, and these might have been counted among these additional structures.

Photographs taken from the top of one of the masts in 1947 include these structures; the main structure centred at 244783,129978 is empty and does not have a roof.
