Our Start to Finish Turnkey Steel Construction Process
A true turnkey service means we handle the vital civil engineering and groundworks phases long before the steelwork arrives on site. We begin with comprehensive site surveys and structural calculations, ensuring the ground can support the substantial loads of modern portal frame buildings. Our team manages all site clearance, excavation, and heavy-duty concrete foundation pouring to establish a level, durable base.
Once the groundworks are securely in place, we proceed with steel frame erection. We supply and install both hot-rolled steel frames for large-span industrial warehouses and cold-rolled steel buildings for cost-effective workshops and storage units. The process finishes with high-quality weather-resistant cladding, roofing, and secure access systems tailored to your operational requirements.

To discuss your build with our experts, request a site survey today by calling 07393 355531.
Delivering a large-scale agricultural barn or a multi-unit industrial estate requires precise coordination. Our start-to-finish project management process eliminates the stress of managing multiple subcontractors. We handle every phase of the build in-house, ensuring flawless continuity from the dirt to the roof.
Every successful build begins with proper site preparation. We conduct thorough topographical and structural surveys to assess soil conditions, drainage requirements, and load-bearing calculations. Our civil engineering team then handles site clearance and ground levelling to prepare a stable footprint.
As experienced industrial estate contractors, we understand that a structure is only as strong as its base. We excavate trenches, install modern drainage systems, and execute concrete foundation pouring. For commercial warehouses and farm sheds alike, we install heavy-duty concrete flooring designed to withstand heavy machinery and intense daily operations.
Our steel building installers and farm shed erection specialists construct the primary skeleton of your unit. We utilise premium galvanised portal frames for maximum structural integrity. Compared to traditional timber frames, our steel constructions offer superior durability, fire resistance, and vast clear-span capabilities without the need for intrusive central support columns.
Once the frame is secure, we install weather-resistant cladding and industrial roofing to create a watertight envelope. We finish the project by fitting commercial roller shutters, secure personnel doors, fire doors, and highly durable fascias. The result is a fully functional, highly secure, and weather-proof asset ready for immediate use.
Partnering with ER3 Group LTD for your next agricultural or industrial build provides distinct operational and financial advantages. We design our turnkey building solutions to offer maximum return on investment for our commercial clients.
Navigating planning permissions and building control can be a complex hurdle. ER3 Group LTD brings extensive regulatory awareness to every project, ensuring your development proceeds legally, safely, and without administrative roadblocks.
For our agricultural clients, we are highly experienced in operating under Agricultural Permitted Development Rights (Part 6 of the General Permitted Development Order). We help farmers design and erect barns, livestock housing, and machinery sheds in full compliance with local agricultural planning criteria, significantly expediting the build timeline.
For commercial industrial estate builds, we adhere strictly to UK Building Regulations. We ensure all load-bearing calculations meet structural integrity codes, fire safety regulations are satisfied through correct fire door installations and compartmentalisation, and proper drainage systems are integrated into the groundworks to satisfy local authority requirements across Sussex, Hampshire, and Surrey.
Based in Worthing, ER3 Group LTD proudly operates across a 50-mile radius, serving rural agricultural hubs and expanding commercial estates. We are widely recognised as the leading farm building companies and commercial construction experts covering West Sussex, East Sussex, Hampshire, and Surrey.

ER3 Group LTD is a fully UK Registered Company (Company Number: 16386146), operating with comprehensive Public Liability Insurance.

We do not rely on outsourced management. Our "Start-to-Finish" capability means the team that pours your concrete foundation is part of the exact same network that erects your steel frame and fits your roller shutters. This guarantees accountability, superior quality control, and a seamless handover process. When you need dependable, risk-free construction, ER3 Group LTD is the local authority.
Yes. We provide a complete turnkey service. Our groundworks team handles site clearance, trenching, drainage, and heavy-duty concrete foundation pouring before our steel erection specialists arrive on site to construct the frame.

Timelines depend on the scale of the footprint and the complexity of the groundworks. However, because we manufacture and erect steel portal frames—and manage the entire site internally—we routinely complete commercial and industrial builds much faster than fragmented multi-contractor approaches.

Answers to common questions about our Agriculture Barn Builds and Industrial Builds
Do you handle the concrete flooring for industrial units?
Yes. We provide a full flooring service, including sub-base preparation and the pouring of reinforced concrete slabs. We can provide different finishes, such as power-floating, which creates a hard-wearing, smooth surface ideal for warehouses and workshops where forklifts are in use.
Can you help with a building if I already have the planning permission?
Absolutely. Many of our clients come to us once they have their "Permission Granted" notice in hand. We can take your approved drawings and turn them into a reality, handling the steel fabrication, groundworks, and erection phases.
What is the typical lead time for a steel frame building?
Lead times vary depending on the complexity of the design and the current demand for steel. However, because we manage the groundworks simultaneously with the steel fabrication, we can often significantly reduce the total project timeline compared to using separate contractors.
Are your buildings suitable for coastal environments?
Yes. For buildings in coastal towns like Worthing, Brighton, or Hastings, we recommend specific cladding coatings and galvanised steel frames that offer extra protection against salt-spray corrosion. We make sure the materials used are fit for the specific location of your site.
