Make us your Structural Engineer of choice

structural engineers in london

As one of the leading structural engineers in London we can provide an engineering service to meet your requirements. We will work in collaboration with your architect and contractor to drive the project forward.

Structural alterations to your property

If you are considering structural alternations or changes to your property you will likely need a structural engineer. As your appointed structural engineer we will produce structural drawings and calculations that are compliant with building regulations.

Once we receive a copy of the existing and proposed drawings we will extensively review them and provide a clear, simple to understand, non obligatory quote.

When instructed us to act as your structural engineer we will arrange for either our principal or one of our senior engineering consultants to visit the property for an initial inspection. We aim to complete this visit within 1 week of instruction and whilst we are at your property we will consider such items as;

  • Locations of load bearing walls
  • Construction of the existing structure
  • Floor joist direction and span
  • Foundation sizes
  • Layout of the existing structure
  • Neighbouring properties
  • Distance and species of trees or shrubbery
  • If previous work has been completed by other structural engineers

Following our visit we will commence our structural design. Using digital (or sometimes hand drawn) files provided by your architect we will save both time and client fees producing our base template. Where necessary a preliminary design will be provided for you to discuss with your architect and/or contractor ahead of producing our final scheme.

We would always recommend that building control are consulted ahead of work commencing on site.

Everyone is different

At Martin Redston Associates we pride ourselves at being consultants rather than simply design engineers. As such, we do just that and consult with you – the client and end user! Once we have issued our scheme we are happy to discuss, clarify and, where appropriate, update our schemes to meet your individual requirements.

Our Services

Structural Inspections

A structural inspection carried out by Martin Redston Associates typically focuses on specific items (such as cracks or other oddities). This will include a review of the area/element in question such as the present condition and predicted integrity. Following our assessment we provide a report detailing issues discovered and what needs to be done to rectify them. Included are details of the structural works required to return the building to a suitable condition. Or, where necessary details of what should be done to retain its structural integrity during & after structural alterations taking place. To find out more about what we can offer please click here.

Rear or side extension

Adding an extension to your home is more popular now than ever due to the relaxation in UK planning laws and regulations. There’s never been a better time to extend your home and get the extra space you’ve been dreaming of.

Our engineers are experienced with the design, planning and construction management of all types of extension. To find out more about what we can offer please click here.

Loft Conversion

Converting your loft space into an extra room is a popular, low-cost way of extending the size of your home. 

Our engineers will ensure that your loft conversion is designed to a high standard and made to last. We will inspect the current structural members and carry out a full survey, before creating a design that meets your requirements, whether you are looking for a “roof window” or “dormer” style roof conversion. We provide a full roof conversion structural engineering service. To find out more about what we can offer please click here.


The number of people completing basement and partial basement projects in London has grown enormously in the last few years. Space comes at a premium price so building on land that is already owned has become increasingly popular. Basements are versatile rooms with lots of uses from games or cinema spaces to a home office or gym. To find out more about what we can offer please click here.

Temporary works

At Martin Redston Associates we can work with your contractor to provide a cost effective and simple solution. We will review the permanent engineering design, complete a site visit then put together a scheme for the contractors use. To find out more about what we can offer please click here.

We work with a number of small and medium size developers bringing the design of both new domestic and new commercial buildings to life. If you are considering a project or would like our input on your design we can help. To find out more about what we can offer please click here.
