<|start_header_id|>assistant<|end_header_id|> Here is a summary of the property description in a single paragraph: A rare opportunity to build a 4-bedroom detached house is available in a convenient location, just 0.5 miles from Rickmansworth town centre and station. Planning permission was granted in 2016 but has since lapsed, offering a chance to reapply and bring the project to life. The building plot is situated on Valley Road, adjacent to Pembroke House, and can be accessed by turning left off the A404 from the Rickmansworth Station roundabout.
