2

Design & Calcs

We draft your structural details and complete all the necessary calculations.

3

Submission

We deliver a combined package ready for submission to Local Authority Building Control or your Approved Inspector.

4

Approval

We stand by our work. If Building Control raises any questions with our solutions, we resolve them promptly at no extra charge.

Straightforward, Fixed Fees

No confusing hourly rates. Know your exact project costs upfront before any work begins.

Frequently Asked Questions

Answers to the questions we're asked most before a project begins.

What does a structural engineer do?

A structural engineer assesses whether a building or structure can safely support the loads placed upon it. For domestic projects, this commonly includes designing steel beams, checking foundations, assessing walls for removal, designing structural alterations, and providing structural calculations for Building Control.

When do I need a structural engineer?

You will generally need a structural engineer if you project involves:

  • Removing a load bearing wall or chimney breast.
  • Building a house extension.
  • Loft conversions.
  • Installing structural steelwork.
  • Constructing retaining walls.

If you are unsure whether engineering input is required, please get in touch and we will be happy to discuss your project.

Can you tell me if a wall is load bearing?

Often yes, with a few details — but a site inspection may be required before we can provide a reliable opinion.

Some walls appear non-structural but support floor or roof loads, while others that appear substantial may not be load bearing at all. A proper assessment considers the structure as a whole rather than the wall in isolation.

Do I need structural calculations?

Many domestic building projects require structural calculations to demonstrate that the proposed structure is suitable for its intended purpose. Building Control will often request these calculations before or during construction.

What information do you need to provide a quote?

Typically the following information is helpful:

  • Property address.
  • A brief written description of the proposed work.
  • Architectural drawings or plans (if available).
  • Photographs of the existing property.
  • Any previous structural drawings or calculations.

If drawings are not available, we can discuss the most appropriate way to proceed.

Please note these details are not required for initial consultations. We can discuss your project over a call first to determine suitability.

Do you visit site?

Where appropriate, yes.

Some projects require a site visit before design work can begin, while others can be completed using suitable drawings and photographs. This depends on the nature of the work and the information available.

Do you provide full Building Regulations drawings?

No.

We provide structural calculations and structural details relating to the structural elements of your project, such as steel beams, lintels, floor structures, and so on.

A full Building Regulations submission typically includes much more than the structural design. Depending on the project, this may include architectural drawings, construction details, insulation specifications, ventilation, drainage, fire safety, energy efficiency, and other information required to demonstrate compliance with the Building Regulations.

Where required, we regularly work alongside experienced architectural designers who can prepare the necessary architectural drawings and coordinate the Building Regulations submission. If you already have an architect or architectural designer, we are happy to work directly with them to integrate the structural design into the project.

Do I need Planning Permission?

Structural Engineering and Planning Permission are separate matters.

Whether Planning Permission is required depends on the nature of your project and local planning requirements. Many domestic projects fall under Permitted Development rights, but you should always confirm the requirements applicable to your property.

Can you arrange Building Control?

We can provide the structural calculations and supporting information required for submission to Building Control where appropriate.

The appointment of Building Control and management of the application is normally arranged by the homeowner, builder or architectural designer unless otherwise agreed.

If you are yet to appoint a builder or architectural designer, we work closely with a number of experienced professionals that can coordinate your project.

Will your calculations guarantee Building Control approval?

No.

Our structural calculations are prepared using the information available at the time and in accordance with the relevant design standards.

Building Control may request additional information or clarification depending on the project, and any approval remains at their discretion.

We do, however, provide ongoing assistance with Building Control queries that relate to our work at no extra charge.

Can builders work directly from your drawings?

Our drawings and calculations cover the structural elements of the project only. They should always be read together, and where applicable, alongside the architectural drawings and any other project information.

Builders should ensure they have all the necessary drawings and approvals before commencing work. If any part of the structural design is unclear, or changes are proposed during construction, clarification should be sought before the work proceeds.

That being said, in relatively straightforward projects, our drawings can sometimes be used as a basis for construction.

Can my builder remove the wall before calculations are completed?

Structural alterations should not normally begin until the structural design has been completed and any necessary approvals have been obtained.

Removing structural elements without an appropriate design may create safety risks and could result in additional costs if temporary support or remedial works become necessary.

What if something changes during construction?

Changes are common during building projects.

If the layout, dimensions, materials or construction method differ from the original design, the structural design may need to be reviewed and, where necessary, updated before the work proceeds.

While minor changes may (in some cases) be accommodated in the original fee, significant changes will incur additional charges.

Can you inspect work on site?

If requested, site visits can be arranged to review aspects of the structural work.

Unless specifically agreed in writing, our structural design service does not include routine site inspections, supervision of construction, certification of workmanship or quality control of the contractor's work.

Can you work with our architect or builder?

Yes.

We regularly work alongside homeowners, architects, architectural designers and builders to help deliver residential projects efficiently. Good communication between the project team helps ensure the structural design integrates smoothly with the overall design.

I don't have an architect or builder, can you help?

Yes.

We work closely with a number of experienced builders and architectural designers who can coordinate and deliver your project as required. Please get in touch to discuss further.

Still have a question?

Every property is different, and no FAQ can cover every situation.

If you are unsure whether your project requires structural engineering, or would like a free quote, please get in touch with a brief description of your proposed works. We will be happy to discuss your project and explain how we may be able to help.
