Commercial Construction & Fit-Out
Commercial Building Services in Hertfordshire & North London
From office and retail fit-outs to commercial refurbishment and maintenance, TCM Building & Maintenance can discuss the scope, access and specialist requirements relevant to your project.
What Commercial Construction Involves
Commercial construction covers any building work carried out on premises used for business purposes — offices, retail units, restaurants, warehouses, healthcare facilities, and educational buildings. Unlike domestic work, commercial projects operate under a different regulatory framework: the Building Regulations apply in full, CDM 2015 duties are more stringent, and the contractual structure (typically JCT) is more formal.
A commercial fit-out can range from CAT A works, such as basic services and finishes, to CAT B interior work including partitioning, ceilings, flooring, building services, data and furniture. TCM can deliver building work directly and coordinate the specialist contractors and professional disciplines required for the project.
