Small Industrial Steel Frame Buildings | Bespoke Fabrication and Installation
Steel frames account for 98.3% of all industrial shed construction in the UK, and for good reason. Steel delivers structural integrity, clear internal spans, and long-term durability that no other material matches at scale. But not all steel frame buildings are equal. There is a significant difference between an off-the-shelf kit assembled from standard components and a building that has been designed, fabricated, and installed to your exact specification by a certified UK fabricator. At Latmet Fabrications, based in Sywell, Northampton, we design and build bespoke small industrial steel frame buildings for business owners, farmers, developers, and operations managers across the UK. Every project is engineered to your site, your specification, and your programme, and certified to UKCA standard under FPC-EXC-2 BS EN 1090-1.
What Is a Small Industrial Steel Frame Building?
A small industrial steel frame building is a bespoke structure built around a structural steel portal frame, designed for industrial, commercial, agricultural, or operational use. The portal frame, comprising columns and rafters connected by moment-resisting joints, provides wide clear spans with no internal columns, giving you unrestricted internal space to configure for your specific operation.
Unlike timber or masonry alternatives, a steel frame building can be erected quickly, is inherently strong, and will perform reliably across decades with minimal maintenance. The frame carries the load of the roof structure, cladding, and any internal equipment such as overhead gantries, mezzanine floors, or heavy plant. Because the building is fabricated to specification rather than assembled from standard kit components, the dimensions, steel grade, connections, cladding, and openings are all determined by what your project actually requires, not by what a catalogue offers.
Small industrial steel frame buildings are suited to a broad range of uses. These include manufacturing and light industrial units, commercial storage and warehousing, agricultural storage and barn structures, workshops, vehicle storage, and covered operational facilities of all kinds. If you need a building that performs to a specific standard, sits correctly on your site, and complies with UK building regulations, bespoke fabrication is the appropriate route.
Latmet Fabrications is certified to FPC-EXC-2 under BS EN 1090-1 and is a UKCA-approved contractor. Every building we fabricate meets the standards required for structural steelwork in the UK market.
Bespoke Fabrication Versus Kit-Build - What Is the Difference?
The steel frame building market contains two distinct types of supplier: kit-build companies and bespoke fabricators. Understanding the difference matters when you are making a significant capital investment.
A kit-build steel building is a pre-engineered structure manufactured from a standard range of components. You select a size from a catalogue, order the parts, and assemble them on site, or pay a contractor to do so. These buildings are designed to cover a wide range of applications generically, which means they are rarely optimal for any one of them. The structural calculations are based on standard assumptions. The dimensions are fixed to the nearest standard increment. The certification applies to the product range, not your specific build.
A bespoke fabricated building is different in every material respect. The design begins with your site, your specification, and your operational requirements. Structural calculations are produced specifically for your location, taking into account local wind and snow loads, foundation conditions, and intended use. The steel frame is fabricated to those exact dimensions in our Northampton facility. Every connection, every column, every rafter section is manufactured for your project. The result is a building that fits your site precisely, performs to the structural requirements your project demands, and carries full UKCA certification under BS EN 1090-1 - the UK standard for structural steel fabrication.
For business owners and developers making a capital investment in a permanent structure, bespoke fabrication is not a premium option. It is the correct approach. A building that has been engineered for its specific location and use will outperform a standard kit across every measure that matters: structural performance, compliance, longevity, and fitness for purpose.
What We Build - Uses and Applications
Latmet Fabrications designs and builds small industrial steel frame buildings for a wide range of commercial, agricultural, and operational applications. Our clients include business owners expanding their operational footprint, farmers replacing or adding storage and working buildings, property developers requiring commercial units, and operations managers commissioning purpose-built facilities for manufacturing, logistics, or storage.
Our buildings cover the following use cases:
- Industrial workshops and manufacturing units — clear-span interiors suited to machinery layout, fabrication, assembly, and production environments
- Commercial storage and warehousing — secure, weather-tight structures for stock, equipment, raw materials, and finished goods
- Agricultural buildings and barn structures — fabricated to the specific requirements of farm operations, from grain and hay storage to machinery housing and livestock facilities
- Garages and vehicle storage — commercial-grade covered storage for vehicles, plant, and equipment
- Covered operational facilities — bespoke structures for sector-specific requirements where standard buildings are not adequate
Because every Latmet building is fabricated to specification, we are not constrained by standard sizes or catalogue dimensions. If your site, your operation, or your planning consent requires a specific footprint, height, or configuration, we design and build to meet it. Contact us on 01604 969 242 to discuss your requirements.
The Fabrication and Installation Process
Understanding how a bespoke steel frame building is delivered from enquiry to handover helps you plan your project with confidence. Below is a summary of the process we follow at Latmet Fabrications.
Initial enquiry and site survey. The process begins with a conversation about your project. We will discuss your site, your intended use, the specification you require, and any planning or regulatory considerations relevant to your location. Where appropriate, we will arrange a site survey to assess ground conditions, access, and any site-specific factors that affect the design.
Design and structural specification. Once we have a clear picture of your requirements, we produce a structural specification for your building. This covers the frame geometry, steel sections, connections, cladding specification, door and window openings, and any structural provisions for internal equipment. All structural calculations are produced for your specific site and use.
Fabrication at our Northampton facility. Your building is fabricated at our facility in Sywell, Northampton. Working to BS EN 1090-1 under our FPC-EXC-2 Factory Production Control certification, we manufacture every component of your frame to the precise dimensions required. This includes columns, rafters, connections, purlins, and all associated steelwork.
Foundation preparation. A steel frame building requires a concrete foundation. We will advise on the foundation specification required for your building, but the groundworks are typically arranged separately by the client. We recommend initiating foundation work in parallel with fabrication to minimise the overall programme.
Installation. Once your foundations are ready and your building components have been fabricated, our team installs the structure on site. Typical lead time from order to installation complete is 12 to 16 weeks, depending on specification and site readiness. Where planning permission is required, this programme should be extended to account for the planning process.
Typical lead time: 12 to 16 weeks from order to installation complete. Early engagement with our team allows your project to be programmed efficiently and reduces the risk of delays.
Planning Permission for Industrial Steel Frame Buildings
Planning permission is one of the most common concerns for buyers considering a steel frame building project. The rules are not always straightforward, and getting this wrong can result in costly delays or enforcement action. This section sets out the key points for industrial and commercial steel buildings in England.
Most new commercial steel frame buildings over 4 metres in height require full planning permission from the local planning authority. This applies to the majority of small industrial steel frame building projects. The application must be submitted to the relevant local authority, and a decision typically takes 8 weeks for minor applications or up to 13 weeks for major applications.
Industrial buildings and warehouse extensions under 200 square metres may qualify for permitted development rights in some circumstances. However, this is subject to conditions covering height, proximity to boundaries, and the class of use. Permitted development does not remove the requirement for building regulations approval, which is a separate process covering structural compliance, fire safety, and energy efficiency.
If your project is located in a conservation area, an Area of Outstanding Natural Beauty, or near a listed building, additional restrictions may apply and full planning consent is almost certainly required regardless of size.
Our advice is to contact your local planning authority at the earliest possible stage in your project. A pre-application enquiry can give you a clear indication of whether permission is likely to be granted and highlight any issues to address before submitting a formal application. We can advise on the general planning considerations relevant to your project, but we do not manage planning applications on behalf of clients. If you require a planning consultant, your local authority can direct you to appropriate resources.
Initiating the planning process early, ideally before or alongside the design stage, is the most effective way to keep your overall programme on track. A planning application submitted in April can typically receive a decision by June or July, allowing fabrication and installation to proceed for autumn completion.

Spring Is the Right Time to Commission a Steel Frame Building
April marks the start of the spring build season, the period when business owners, farmers, and developers planning new buildings for summer or autumn completion are actively researching and commissioning projects. For steel frame buildings, the timing of your order has a direct bearing on when your building will be ready for occupation.
With a typical lead time of 12 to 16 weeks from order to installation, a project commissioned in April is realistically on track for completion between August and October 2026, before the conditions that make outdoor construction work more challenging in the autumn and winter months. If your project also requires planning permission, an application submitted now can receive a decision in time for fabrication to begin without delay to the overall programme.
If you have a building project in mind for 2026, now is the time to begin the conversation. Contact Latmet Fabrications on 01604 969 242 or use our enquiry form to request a quotation. All pricing is provided on application, based on your specific site, specification, and programme requirements.

Do I need planning permission for an industrial steel frame building?
Most new commercial steel frame buildings over 4 metres in height require full planning permission from the local planning authority. Industrial extensions under 200 square metres may qualify for permitted development rights, subject to height, boundary, and use conditions. Permitted development does not remove the need for building regulations approval. We recommend contacting your local planning authority at the earliest stage of your project to confirm what is required.
How long does it take to build a steel frame building?
Our typical lead time is 12 to 16 weeks from order to installation complete, depending on specification and site readiness. Where planning permission is required, this should be factored into your overall programme, minor applications typically take 8 weeks and major applications up to 13 weeks. We recommend initiating both the planning process and your fabricator enquiry as early as possible to keep your project on schedule.
What does UKCA certification mean for my building project?
UKCA (UK Conformity Assessed) is the post-Brexit conformity mark required for structural steel products placed on the UK market. Latmet Fabrications is certified to FPC-EXC-2 under BS EN 1090-1 — Factory Production Control, Execution Class 2. This certification covers structural design, material traceability, welding quality, and compliance with UK building regulations, and provides assurance that your building has been fabricated to the required standard.
What is the difference between a bespoke fabricated building and a kit-build?
A kit-build steel building is a pre-engineered standard structure assembled from off-the-shelf components. A bespoke fabricated building is designed and manufactured to the client's exact specification, including site-specific dimensions, structural calculations, steel grade, and cladding. Bespoke buildings carry full UKCA certification specific to the project, are engineered for the precise location and use, and are fabricated and installed by the same team throughout.
