How It Works

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.

1. Site Survey & Civil Engineering

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.

2. Groundworks & Foundation Pouring

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.

3. Steel Frame Erection

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.

4. Roofing, Cladding & Finishing

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.

The Benefits

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.

  • Seamless Project Speed: By controlling the entire process—from groundworks to steel erection—we minimise delays commonly caused by overlapping subcontractors.
  • Unmatched Durability: As premier farm shed builders and industrial unit builders, we use heavy-duty galvanised steel, robust concrete hardstanding, and weather-resistant cladding that require minimal maintenance over their lifespan.
  • Cost-Efficiency: A true turnkey service means accurate budgeting from day one. You avoid hidden costs, site management fees, and material delays.
  • Bespoke Design Adaptability: Whether you need vast grain storage construction pre-harvest or a partitioned commercial warehouse, our portal frame designs are entirely bespoke to your operational needs.

Local Compliance & Planning

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.

Frequently Asked Questions (FAQs)

Do you handle the groundworks as well as the steel frame?

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.

Can you build structures under Agricultural Permitted Development Rights?

Absolutely. We frequently work with farmers and landowners under Part 6 of the General Permitted Development Order. We ensure the footprint, height, and location of your agricultural barn comply fully with the necessary regulations to avoid full planning permission delays where applicable.

How quickly can you erect an industrial warehouse?

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.

Do you provide warranties and insurance?

ER3 Group LTD is fully covered with comprehensive Public Liability Insurance, and our workmanship is carried out to exact UK Building Regulations, ensuring long-lasting structural integrity and safety.

FAQ

Frequently Asked Agriculture Barn Builds and Industrial Builds Questions

Answers to common questions about our Agriculture Barn Builds and Industrial Builds

Do I need planning permission for a new industrial unit in Worthing?

Yes, most commercial and industrial builds require full planning permission from the local council. However, some smaller extensions or specific agricultural buildings may fall under permitted development. We can help you identify which rules apply to your specific site in Sussex or Surrey.

How long does it take to build a steel portal frame warehouse?

The timeline varies based on the size of the unit and the complexity of the groundworks. Generally, a steel frame can be erected in a matter of weeks once the foundations are set. A full turnkey project from site prep to handover usually takes a few months, which is significantly faster than traditional builds.

Can you handle the concrete flooring for heavy machinery?

Yes. We specialise in commercial groundworks and can pour reinforced, power-floated concrete slabs designed to take the weight of forklifts, HGVs, and heavy industrial plant equipment.

Do you offer repair services for existing industrial units?

While we focus on new builds, we also handle significant refurbishments, including stripping and replacing old cladding, installing new roofing systems, and upgrading roller shutters to improve site security.
