Residential Renovations, Alterations, and Additions

Whether you’re modernising an older home or expanding to suit your family’s changing needs, Heymans & Associates provides practical structural engineering solutions for a wide range of residential alterations and additions. We work closely with homeowners, builders, and designers to ensure every modification is safe, compliant, and designed for efficient construction.

Open-Plan Living Spaces

Many homeowners choose to remove walls to create brighter, more connected living areas. We provide the structural design required to safely remove load-bearing walls, install beams, and support the surrounding structure. This allows you to open up kitchens, dining rooms, and living spaces so you can enjoy better natural light and improved interaction throughout the home.



Sub-Floor Storage Solutions

Where additional storage is needed, we can assess opportunities to create usable sub-floor space. This may involve removing existing brick piers and designing strengthening works to support the floor structure above. Our engineering ensures the modifications are carried out safely while maximising the available storage area beneath your home.


Building Condition Reports

We provide detailed building condition reports to assess common structural concerns in residential properties. Reports can cover structural brickwork cracks, leaning retaining walls, drainage issues, and building subsidence caused by ground movement. Our findings help homeowners understand the cause of the problem and provide clear recommendations for repair or further investigation.
