Steel Building Extensions & Refurbishments for Industrial & Commercial Businesses in Kent, Essex, East & West Sussex

Steel building extensions and refurbishments allow you to maximise an existing building on your land. Extending your factory or warehouse is the most cost effective solution for a business looking to scale up or modernise its capacity. BM Steels offer experience and understanding in transforming and expanding your existing commercial or industrial space and will rise to any technical challenges to achieve that.

BM Steels provide steel building extensions and refurbishment for commercial and industrial projects in the South East of England. We can handle all aspects of a project, from initial design and planning through to build, or we can just provide the individual services you need to complete a project.

Our Services:

Re-roofing, Re-cladding & Insulation:

Your existing steel building may be suffering from storm damage or in need of weather repair. We can re-roof the existing structure and also add new cladding and insulation to bring it in line with modern specification and regulation.

Reconfigure Existing Layouts:

Your steel building refurbished space can also be totally reconfigured to improve production, work flow or new requirements. New openings can be created and mezzanines added to provide additional workspace.


In preparation of your steel building extension, existing land may need to be cleared. We provide either hard or soft demolition services. Any waste management is handled responsibly, including hazardous materials like asbestos, ensuring your site is safe and compliant.


We offer professional groundwork services for all our industrial and commercial projects. These services include: groundwork design, borehole sampling, core sampling, piling, pad foundations, strip foundations, drainage and the safe removal of waste materials.

Hot Rolled & Cold Rolled Steel Buildings:

If your steel building extension or refurbishment, is in non-regular space or it is larger in scale, we will provide a bespoke hot rolled solution. For more more straightforward projects where the structure isn’t too high, the space can facilitate a regular building footprint or there is no load-bearing requirement, a cold-rolled is the perfect solution.

Plans, Engineering & Design Drawings:

Our full design and engineering package for extensions, includes a full set of preliminary plans and drawings to support your planning application, as well as, detailed engineering and structural drawings. We can also provide for projects design plans for groundwork, cladding, steelwork and second-fix.

Site Surveys & Professional Statements:

For a site survey, we can conduct borehole drilling, core sampling, drainage, electro-magnetic and topographical surveys, as well as WAC testing. We also ensure all necessary professional statements for any local authority validation process are provided eg. CIL, SuDS, Transport Assessment etc.

Planning Applications & Building Control Applications:

We are experienced in liaising with local authorities across Kent, Surrey, East Sussex, West Sussex and SE London in getting your Planning Application approved. We can also manage your Building Control Application, ensuring that all building regulations are met and your application is approved.

We also provide each of our professional services individually
