Side Return Extension
A Side return extension is a great way to maximise the potential of your property and typically involve the creation of a larger kitchen diner. A side return is a solid investment and there are many ways to maximise your investment with the right construction team.
A proactive construction team would seek permission to construct the external walls astride the boundary to benefit you and your neighbour. Whilst this isn’t always approved it often isn’t requested at all leaving a missed opportunity for all parties to maximise internal space.
Internal Structure
The internal structural design is key when adding a side extension. One of the biggest challenges with a side return is maximising height and this needs to be a key consideration for the architect, engineer and construction team. Often the steel frames that are required for an extension are large and can cause height issues at the transition point between the existing space and the new space.
In order to maximise height all involved should consider the size of steels installed as well as the possibility of setting them within the floor structure above. This is not always a possibility as often the space directly above is a fully finished bathroom and the entire space would require significant work, but this should be considered in most cases.
Planning Permission
Planning permission is commonly approved for a side return and there are guidelines in place to make the architectural design and planning process a little simpler. Key considerations for any architect looking to obtain planning approval are the boundary height for the new construction, roof type and extension depth as it relates to natural light impact on neighbouring properties.
An experienced architect will navigate these issues in advance of the planning application and look to ensure that there is little time lost making significant architectural changes post application. Here is a guide to general information about planning permission.
