The Hull-based firm is now part of a team working on a £5m project at Smith & Nephew in Hull, and has recently completed its part of a £4m construction project at the former Seven Seas site where independent aluminium supplier Eltherington is moving into a new factory.
The new contracts have helped to create four new jobs, and boost Ridings’ turnover to around £300,000, with figures expected to double in the next year.
Directors Liam Beardshaw and Ian Grimwood founded the business in May 2015, and managed to secure £300,000 worth of contracts within their first 24 hours of operation.
The company offers energy efficient design services for all building services installations.
It operates in a wide range of buildings including commercial, industrial, healthcare, public and private sectors.
Mr Beardshaw said: "We said before that the instant growth of the business had taken us by surprise and that has continued.
"That’s down to a combination of more work from existing contacts and appointments from new clients. Basically the projects have become bigger and more challenging."
Projects include residential development at St Leonard’s on Sea, renovations and refurbishments of various psychiatric units for Hull Citycare and the design of new laboratory facilities to the Smith & Nephew site in Hull.
"The pace of expansion has exceeded our expectations and we’re fortunate to be at The Deep Business Centre, where the team are well-versed in providing expanding companies with the extra space they need at short notice," added Mr Beardshaw.
"Our new offices should be big enough but the way things have been going it’s hard to tell. We’re also picking up a lot of work in the modular buildings sector, particularly involving school sites around the country, and we’ve also got longer term projects in the pipeline.
"That will need more staff, and we’re committed to training and developing our team."
