Structural Engineers Brighton

SWJ are Structural Engineering Consultants that cover Brighton and the south coast.  We’ve worked with private clients from Newhaven to Bognor Regis to Arundel,  and specialise in new builds, and large and complex extensions including loft conversions & basements.

If you have a property in Brighton or the surrounding area and are planning a completely new build or a complex extension such as a basement or even a swimming pool  – it is never too early to contact SWJ Consulting and talk about any new plans or large structural alterations to your home or property.

Increasingly UK property owners, and developers, in popular holiday destinations such as Brighton, are investigating basement extensions or large scale loft conversions, as a way to increase living space. We have the experience and the expertise to let you know, very early in the process,  if your home is suitable for a significant extension that won’t alter the building’s footprint.

We specialise in large and luxury residential projects for private clients to ensure their visions, and their architect’s visions can be realised. Many people don’t realise that a large percentage of the costs of an extension, or new build, is in the ground – in the foundations. This of course is especially true of basements and swimming pools. By talking to us early on in the process, we can complete a feasibility study before you spend money on any designs or planning applications.

Structural Engineers, like ourselves,  are vital when it comes to understanding whether you can have the extension, annexe, basement or swimming pool you desire and we can ensure the plans are then correctly implemented.

About SWJ Consulting

We are based in Oxfordshire so are perfectly placed to service clients in Brighton and along the south coast.

If you are considering a large extension, swimming pool, or basement then contact us and talk to us about your new project. We will work with you, and your architect, to ensure the design you want is achievable. The worst outcome for a client is to fall in love with a design from your architect and then find out you need to compromise on the design because of structural concerns.

How we work

  1. We complete a site visit to identify any potential issues and check over any existing plans
  2. We will then produce initial design ideas for any feedback or questions from you and your architect
  3. Once the design is finalised we will complete detailed drawings for your contractors, architect and warranty provider

Large commercial residential projects

We were asked to design an extension with 62 additional self-contained apartments for this extra-care facility. The extension included a semi-basement and is an example of how we work in cooperation with other contractors, to anticipate and avoid any issues on site.

Basements and extensions for Brighton homeowners

This project is similar to the types of homes and projects we’re asked to look at in Brighton. This luxury home was refurbished and extended with the addition of a third floor as well as a basement and extension to the back of the house.

Brighton’s listed and Historic Buildings

We have extensive experience with historic and listed buildings, for both developers and private clients – and frequently work with Historic England. This project was the restoration of 18th century listed barns and the addition of new buildings for a developer.
