The Upton 'pre-fabbery' was located on Molyneux road, off Greasby Road (now Old Greasby Road) and was used to re-house some of the people made homeless during the bombing of Birkenhead. The Prefabs were constructed out of aluminium and where delivered from the factory in three or four large pieces that could be assembled in under three hours. The Prefabs came complete with fitted kitchens and bathrooms.

For the first time, many young families found themselves living in well-designed accommodation with hot and cold running water, new electric appliances, and an inside bathroom.

The Upton Prefabs survived for nearly 30 years, but where replaced with the conventional houses which now occupy Molyneux Close and Greystoke Close. These houses have themselves recently been refurbished.
