Our Services

Commercial Projects

At Prostructural Designs, we handle the structural engineering for all types of business properties, from new shop fronts and office fit-outs to large industrial warehouses. Our main priority is ensuring your building is safe and structurally sound while keeping the design as efficient as possible. We work closely with developers and contractors to provide practical plans that keep your project on track, helping you avoid wasting budget on unnecessary materials.

Residential Projects

Planning a new build, a loft conversion, or a rear extension? If you are altering an existing property—from removing a chimney breast to knocking down a load-bearing wall—we are here to help. We provide the professional structural calculations and steel beam (RSJ) designs your builder needs and Building Control requires. Whether it’s a small renovation or a large family home, we ensure every change is safe, legal, and built to last.

Design Consultancy

Before you start building, Prostructural Designs helps you figure out if your ideas are actually possible. We look at your plans and provide expert advice on the best way to build them safely and efficiently. By spotting potential structural issues early on, we save you from expensive mistakes later in the project. Our goal is to make sure your design is buildable, solid, and cost-effective from the very beginning.

Building Regulations Advice

Getting approval from Building Control can be a confusing part of the process, but Prostructural Designs makes it simple. We take care of the technical side by providing the exact structural drawings and reports the inspectors need to see. We ensure everything we design meets current UK Building Regulations, so you can get your official sign-off and complete your project without any legal or safety headaches.

Getting Your Project Ready to Build

At Prostructural Designs, we don’t just produce drawings—we help make your project run smoothly from start to finish. As experienced structural engineers, we focus on creating designs that are clear, accurate, and easy to build, reducing stress and unexpected issues during construction.

We use advanced 3D modeling technology to create a full digital model of your structure before construction begins. This allows us to identify and fix potential problems early, such as misaligned elements, unclear details, or clashes between different parts of the structure. By resolving these issues upfront, we help avoid costly changes, delays, and confusion on site.

Our 3D models provide a clear visual reference for builders and trades, making it easier to understand how everything fits together. This improves communication, reduces errors, and helps ensure the build progresses efficiently and safely.

The result is a well-coordinated, reliable structural design that saves time, controls costs, and gives builders and homeowners confidence throughout the construction process.

Our Structural Engineering Services

Whether you are at the very beginning of an idea or ready to start construction, we offer a full range of support:

Feasibility & Planning: We help you check if your site is ready for building and if your ideas are physically possible before you commit to a design.
Full Design Packages: We provide everything your builder needs, including detailed structural designs, technical drawings, and final certifications.
Home Alterations & Extensions: We specialize in all house types, providing calculations for loft conversions, rear extensions, and removing internal walls.
Steel-Framed & Commercial Builds: From industrial warehouses to steel-framed offices, we design strong, efficient structures for any business use.
Structural Inspections & Reports: If you are worried about a crack in a wall or buying a new property, we provide expert inspections to give you an honest assessment of the building's health.
Design & Build Support: We work alongside your contractors to ensure the structural side of the build is handled correctly from start to finish.

To make sure every detail is perfect, we use modern design software to visualize your project. This helps us spot potential issues early, evaluate any risks, and ensure your building is as safe and efficient as possible.

Frequently asked questions

General Services

A structural engineer is a professional responsible for designing the 'skeletal framework' of a building to ensure it is safe, stable, and compliant with all relevant regulations. You need one for any project that alters or affects a load-bearing part of your property, such as:

We provide expert structural engineering for both residential and commercial projects. Our core services include:

Home Extension Structural Design
Loft Conversion Design
Internal & External Load-Bearing Wall Removal
Chimney Breast Removal (including Gallow Bracket design)

We work with all parties. We can collaborate directly with your appointed architect or contractor, or work with homeowners who need a structural design package before hiring a builder.

Timelines vary, but we prioritise efficient service. Once we have all the required information (architectural plans, site photos, dimensions), a typical timeframe is:

Simple Wall Removal: 3–5 working days.
Extension/Loft Conversion: 7–12 working days.

We carry comprehensive Professional Indemnity Insurance (PII). This essential coverage protects you in the unlikely event that an error is found in our design or advice. We can provide proof of our PII certificate upon request.
