RH Irving Construction’s work will be a familiar sight to many.

From those jetting off on holiday from Manchester Airport, to people living in new build homes, to the hundreds of thousands who flock to garden centres each weekend.

This year the company, which is based in Longtown, is beginning work on another high profile contract; the multi-million pound task of restoring the historic lido and promenade at Grange-over-Sands, overlooking Morecambe Bay.

Over the last half century, the company has grown its offer to work on a wide range of civil engineering, construction and infrastructure projects, as well as new builds including Houghton Hall Garden Centre, in Carlisle, and around 10 other garden centres across the country.

Other projects of note include the Johnston Centre project in Kirkcudbright, which involved the refurbishment, upgrading and alterations to a Grade B listed building and large new garden centres in Falkirk and Stokesley, North Yorkshire, for Klondyke Group.

The company, which employs 100 people with a turnover of around £20m a year, built and moved to new offices in Longtown in 2005.

This year the company is starting work on the £6.8m project to restore the lido and promenade in Grange-over-Sands, which it hopes to complete next spring.

Work on the lido will include an upgrade of the central pavilion and the development of a landscape feature within the former pool area.

The male and female changing rooms will be mothballed internally for refurbishment at a later stage, although some stabilisation work will be carried out on the roof and terraces, as well as cleaning and decoration on the outside.

Repairs will be made to the concrete terracing around the perimeter of the pool, including concrete repairs to the diving board structure.

When the work is complete, people will have full access to the seating terraces that overlook the central pool space. Work on the 1900m-long promenade will include the removal of unstable sections and repairs to the seawall.

It is hoped that in time Westmorland and Furness Council will work with a commercial partner so the site can be run as a swimming pool once more.
