Repair, Extension or Conversion

Structural integrity must be maintained whenever a residential property undergoes repair, extension or conversion.

AC Design engineering services ensure the construction of a new build, residential home property or commercial building is stable.

The primary focus is upon key structural components, including:

  • Foundations
  • Walls
  • Columns
  • Beams and roof members


Improving the structural integrity of existing buildings involves preparing a comprehensive structural analysis, dimension surveys, reports and drawings.

The advice and services of residential structural engineers will also be called upon whenever the stability of a property is affected by:

  • Subsidence
  • Fire
  • Flooding
  • Explosion


The degree of damage is carefully assessed to decide the necessary remedial action required.

How we guide you through the process

A home renovation, such as a loft conversion or party wall extension often involve a structural engineering solution which demands considerable detailed planning and preparation. Our approach at AC Design is to help and guide you through the process as clearly and simply as possible, including:

  • Initial site visit – to discuss the proposed work and desired outcome.
  • Structural designs – produced from architectural plans provided or a survey. Structural information for the design are clearly shown and carried out.
  • Assessment of the proposed alterations and new structure required. This enables loads to safely flow through to the footings.
  • Building control calculations. Used in producing drawings for building construction and costing.
  • Impact assessment of local ground conditions – using geological maps, trial pit excavations and full soil testing.
  • Information compiled and issued – to comply with Part A of the building Regulations.

We offer:

Full support for structural engineering projects

AC Designs provide full support for a comprehensive range of structural engineering projects, to scale. Our residential engineer and architect services, include:

Full compliance with building regulations

We can also help with all aspects of building regulations, providing full compliance support for both residential and commercial projects, from loft conversions to property renovation and house extensions.

The main task of a residential structural engineer is to ensure properties are:

  • Made safe – and –
  • Capable of withstanding both internal and external forces, and elements.

Robust, detailed planning

Private homeowners planning major property alterations will need a structural engineer to provide essential design, space planning, surveying and inspection work.

A structural engineer will carry out the required calculations and create drawings needed for building control approval. They will also be used by the builder for accurate pricing and to carry out the building work.

Residential structural engineers will always be required for any new, additional construction, such as building a porch or balcony.

Structural engineering for contemporary interior home design

The renovation, conversion or extension of a residential property always requires in-depth and detailed knowledge of its current structural condition. There could be a significant safety risk of homeowners starting a house conversion or similar building project without a full understanding of the various complex structural forces involved. Any number of major repairs could be needed to address often hidden, undiagnosed faults. There could also be a further serious cost for non-compliance with statutory planning permission and other regulatory conditions.

Open plan spaces

Contemporary residential interior design increasingly specify for rooms as large, open plan spaces, which invariably demand more innovative and rigorous structural solutions.

An extension, for example, always requires a structural survey and engineering of the foundations, walls and roof. It’s essential that the correct and precise structural design is calculated for supporting the first floor, wall and roof above the opening into an extension.

Early stage design changes

Engaging the professional company services of a structural engineer is always necessary when planning a large renovation or conversion, including projects involving a party wall. A structural engineer should be involved at an early stage to help identify minor design changes, as well as large scale alterations, which could prove costly to later rectify.

Inspections and Investigations

The services of a structural engineering company are essential to carry out an advance survey, inspection and investigation into the condition and safety of a residential structure. Either before purchase, renovation, or conversion. AC Design regularly carry out detailed inspections and investigations into existing buildings, their defects and current condition. Typical issues can include:

  • Increasingly adverse affects of environmental pollution upon concrete.
  • Any sign of corrosion in a building’s steelwork causing expansion, and cracking open masonry facades.

A variety of tests can be carried out to determine current suitability.

Subsidence & Movement Surveys

House movement is a common structural engineering task. Especially, in London and its ageing building stock clustered in numerous locations.

Laser surveys scan the external facade of a building to provide highly accurate details of wall surface distortions, such as leaning and bowing.

Dimension Surveys

Dimensional surveys is a structural engineering technique to accurately measure 3-dimensional spaces. The area between each point is precisely determined to create digitally mapped distances and angles.

Building Failures

Inspection of dangerous structures at short notice is not unusual.

Our extensive structural engineering knowledge of historic and listed buildings allows a quick but reliable assessment to determine the extent of further detailed investigation and remedial work required.

Mortgage Surveys

A structural engineers appraisal of a residential property to support a mortgage application can often be requested just days before the exchange.

Survey reports specific to the property are completed by a chartered engineer. Each and every property defect item will be itemised, and where possible, appropriate repairs and anticipated costs evaluated.

When planning approval is needed for your residential project

If your project needs planning approval – and it’s likely that your plans will need to be modified. The recommendation is to first obtain planning permission before appointing the services of a structural engineer to prepare the necessary structural drawings and calculations. All and any alterations will require amendments to be made, and structural engineers will be working alongside your architect to prepare the drawings.

When planning approval is not needed for your home renovations

If your project doesn’t require planning approval – you are recommended to first appoint a professional structural engineer with your clearly defined brief. The structural engineer will arrange to visit your home, inspect and take measurements. Precise calculations and drawings will be produced for the building control application, and also forwarded to the builder for the quotation and use during the building phase.
