The group, a 'one-stop shop' property support services company, has engineered the buy-out in a bid to expand its range of services - a move which could also lead to the opening of new LRW offices in the UK and overseas.
LRW is involved in a raft of projects across the North West, including the redevelopment of Manchester City's former home at Maine Road, the regeneration of Wigan town centre and the new Malmaison hotel in Liverpool (pictured).
Peter Roberts, a director of LRW said:
'We believe the change will bring significant opportunities to both the business and our employees, consolidating our existing substantial workload and enabling us to pursue and actively promote business in other sectors nationally and ultimately onto the international stage.
'However, on a day to day basis it's pretty much business as usual.'
Over the years the practice has been involved in a number of major developments, such as the Trafford Centre, the new airport at Doncaster, and a range of office, hotel and leisure schemes.
Neil Bellis, chief executive of Erinaceous Group, added: 'We welcome LRW to the group. The addition of a significant architectural design practice to the group broadens and deepens the services we can offer to existing customers, and we hope that LRW's customers will similarly benefit from the range of property support services now available to them as part of a larger group of companies.'
