Bulbourne Yard is an historically important purpose built canal maintenance yard that operated for nearly two centuries, only moving when the buildings could no longer accommodate mechanised production.

The Listed buildings are unmatched on the canal network for their completeness.

The Grand Union Canal, originally the Grand Junction Canal, was constructed as a short cut from Brentford in West London to Braunston in the industrial Midlands.  The Act of Parliament to allow the canal to be constructed was passed in 1793.   Construction started at the two ends of the canal simultaneously.  The Tring Summit was completed by 1797 and opened in 1799.

By 1811 the bridge over Icknell Road had been built and there appears to be a house in the current location of Plot 14.  This was named the surveyor’s house, the surveyor being James Barnes.

The four Listed buildings seem to date from 1849 and are shown on the 1882 map.

The map of 1899 shows the three cottages at the entrance of the site, Plots 4, 5 and 6, and also the tramways were insitu.

The new CRT office building was shown in the map in 1924.
