Structural Calculations

If you require a quote for a larger domestic building project such as a single or double storey extension, loft conversion, new build dwelling or a refurbishment scheme contact us today to help you with your home conversion. We can help you save time and money with our calculation packs for Building Control approval for your home conversion. This includes full structural plan packages, beam calculations for extensions, beam calculations for loft extensions and any other project planning assistance you may require.

At we offer a fully digital, paperless and streamlined calculation service for all domestic building projects. You can have the calculations you require for Building Control approval in a digital PDF format in a matter of days, depending on the scale of the project. This means you can get your building project started quickly and without any unnecessary delays.

To get your plans and beams calculations, you can email your architectural plans and supporting information to us using our simple online submission forms. Once we have your plans and project information, our expert team will be able to calculate you a bespoke plan for your home conversion.

Of course, we initially provide a full quote for our services based on the information you have provided to us. Our quotes are individually prepared for our clients based on the size and complexity of the overall scheme and the time we think the project will require. Larger jobs usually attract a reduction in fee. Every home conversion project is unique and we take everything into consideration to provide you with a competitive quote for our expert services. Once we’ve assessed your requirements, we simply email you with your bespoke proposal. It’s then down to you, but we’re confident you’ll agree we offer excellent rates.

All enquiries we receive are replied to the same working day! We know how frustrating it is to encounter delays! If you are satisfied with our realistic fee proposal, simply confirm to us that you are happy to proceed. We’ll then book your project onto our system and get to work on your beam calculations for extensions, beam calculations for loft extensions, full structural plans and all other requirements.


We understand that every project is entirely different, that’s why our team look forward to helping you create your new home conversion to the very highest standards.

Loft Conversions

Our loft conversion structural calculation packages contain everything which is required to obtain Building Control approval, material ordering and builders reference. All we require from you is a copy of your architectural plans or a detailed measured survey of the property.

Our loft conversion structural calculation pack includes calculations for all elements of the structure which need to be newly constructed or modified on site. This includes forming the new floor and roof structures.

As standard, our calculation packs include all the following calculations and details. However, as all projects vary in nature and subsequently have differing requirements, this will be individual and may vary from scheme to scheme.

All steel beam calculations for loft extensions and beam calculations for extensions, including padstone/bearing plates and splice calculation and fabrication detail (These may be required for both floor and roof support)

Floor joist calculations, including trimming joists

Rafter/roof modification calculations

Dormer structure construction details (If your scheme includes a dormer)

Full sketch details and layout drawings

All this is delivered to you in digital PDF format quickly and efficiently. Our team of experts pride themselves on their accuracy and presentation.
