Structural Design Services
Complete structural design and calculations for residential and commercial projects across the UK, taking your project from initial concept through to final, build-ready drawings.
What Is Structural Design?
Structural design is the engineering process of planning, analysing and designing the structural elements of a building so that it can safely carry the loads placed upon it and remain stable throughout its life. It ensures that elements such as beams, columns, foundations and connections perform correctly and comply with UK Building Regulations and relevant British Standards. At LENIO Group, we provide complete structural design and calculations for residential and commercial projects across the UK, taking your project from initial concept through to final, build-ready drawings.
We do far more than produce calculations. Our engineers carefully analyse the loads, materials and site conditions involved in your project to create efficient, practical designs that contractors can build with confidence. This approach reduces the risk of on-site issues, delays and additional cost, and helps your project progress smoothly from design to construction.
Our Structural Design Services
Residential Structural Design
We provide structural design solutions for all types of residential projects, including house extensions, loft conversions, internal wall removals and new builds. Our designs ensure that your home improvements are structurally safe and can be approved by building control authorities.
Commercial Structural Design
Our commercial structural design services support offices, retail buildings, warehouses and mixed-use developments. We focus on delivering efficient structural systems that provide safety, durability and cost-effective construction.
Steel Structure Design
We design steel beams, columns, frames and connection details for both residential and commercial projects. Our steel designs are developed to ensure strength and stability, as well as ease of fabrication and installation on site.
Reinforced Concrete Design
We provide reinforced concrete structural designs for foundations, slabs, retaining walls and structural frames. These designs are engineered to handle all relevant load conditions while ensuring long-term durability and safety.
New Build Construction
We offer complete structural design solutions for new residential and commercial buildings, from initial concept through to construction. This includes foundation design, load calculations and framing systems, all developed in full compliance with building regulations to deliver a safe, efficient and buildable structure from the ground up.
Structural Calculations
We prepare the detailed structural calculations required for building control approval and construction. These calculations demonstrate that all structural elements meet safety standards and perform correctly under the loads they will carry.
Structural Inspections and Reports
We carry out structural inspections and prepare detailed reports to identify defects, assess structural safety and recommend remedial solutions. This service is well suited to property owners, buyers and insurance requirements.
Our Structural Design Process
Every project begins with an initial enquiry and consultation, where we review your requirements, gather site information and provide initial guidance on feasibility. We then carry out a site visit and structural assessment to inspect the property, record site conditions and identify the load-bearing elements.
Using established engineering software and UK design standards, we complete the structural analysis and design calculations to confirm that the proposed scheme is safe, stable and compliant. We then prepare clear structural drawings, including layout, reinforcement, and steel and concrete details, coordinated with the architectural plans so the design can be built accurately on site. Where required, we also provide support for the building regulations submission, preparing the necessary engineering documents.
Quality Assurance Built In
Every drawing we produce passes through our structured quality assurance process, progressing through preliminary and detailed design stages before being issued as Good for Construction. Each drawing is prepared, checked, independently reviewed and approved by a dedicated project team, which means high accuracy, full compliance with UK standards and clear accountability at every stage.
Who We Work With
We provide structural design services for homeowners, architects, contractors, property developers, commercial businesses, builders and mortgage brokers across the UK.

Frequently Asked Questions
Structural design is the engineering process of planning and designing the framework that keeps a building safe and stable. It ensures that structural elements such as beams, columns, walls and foundations can carry the loads placed upon them without failing. A well-prepared structural design also demonstrates compliance with UK Building Regulations and relevant British Standards. At LENIO Group, we translate this analysis into clear calculations and drawings that your builder can construct with confidence.
You typically need structural design whenever you make a structural change to a building. Common examples include removing a load-bearing wall, building an extension, converting a loft, or constructing a new structure. In these situations, a structural engineer confirms that the new arrangement can safely support the applied loads. Engaging an engineer early helps avoid delays and ensures your project meets building control requirements.
In most cases, yes. Building control authorities usually require structural calculations to confirm that your project meets UK safety and construction standards. These calculations demonstrate that each structural element has been designed to carry its intended loads. We prepare clear, submission-ready calculations to support your building control application.
Yes, but only with a proper structural design prepared by a qualified structural engineer. Removing a load-bearing wall requires a suitable support, such as a steel beam, to safely transfer the load that the wall was carrying. Building control approval is usually needed before the work begins. We can carry out the assessment, design the support and provide the calculations you need.
Most residential structural design projects are completed within a few working days to two weeks, depending on the scope and complexity of the work. More complex or larger projects may require additional time for analysis and coordination. If you have a specific deadline, please let us know, and we will advise on timescales and work to accommodate your requirements wherever possible.
