Sorry for the late reply, been away from my computer for a week.
Unfortunately I have not come across W H Dickinson, but I believe that Ridley Villas was his office address. The remaining property still called 'Ridley Villas' where the LUNN family lived, died or went bankrupt, is unusual in that it still exists, where all the other properties that were also called Ridley Villas were demolished and I believe now have student accommodation for Newcastle university built on top. I wondered how or why it had survived, but I came across the following document from Tyne and Wear Museums Archaeology Department:
Name: Ridley Villas, 91, New Bridge Street, Shieldfield,
ID: 195 Ward: Ouseburn
STATEMENT OF SIGNIFICANCE: These Georgian villas of the 1820s were once part of a row of grand houses and may have been designed by John Dobson. The villas were built on land belonging to Sir Matthew White Ridley. Domestic use of the villas ceased in 1913/1914 when the building was converted into a TB hospital. By the 1960s Ridley Villas was being used as a general medical unit, which closed in 1972. The two storey brick and stone villas are now a hostel.

Abstract:
An archaeological assessment was compiled in response to a proposal to redevelop the site. The site was potentially one of great archaeological interest, as the available evidence marked it as the location of Shieldfield Civic War Fort. This earthwork was an intrinsic part of the defenses of the city during this period of great unrest and a monument class on which a relatively small amount of archaeological research had been undertaken. It was highly likely that the remains of the defensive ditches would remain within the site. Further archaeological evaluation was recommended.
I have visited the house and the area next to it is called Shieldfield. I am not sure what the property is still used for but it does not look residential.
Sorry I could not help with your ancestors only their place of work.
