He says: “What makes my job so satisfying is the pleasure of seeing the spaces we’ve created and, of course, the happiness we’ve achieved for our clients who now have a wonderful space to enjoy for many years to come.”

Over the last 10 years, A-SPEC has grown significantly. The professional team now consists of 8 skilled and experienced craftsmen and 2 office support staff, who are all dedicated to providing the best possible customer journey.
