Planning & Building Information
Not all house extensions require planning permission. Some single-storey rear extensions, side extensions, loft conversions and other alterations may be possible under permitted development rights, subject to the property and the proposed works meeting specific criteria.
Larger extensions, certain two-storey extensions and projects affecting listed buildings, conservation areas or properties with restricted permitted development rights may require a formal planning application.
As part of our extension design and consultation process, Lewis Home Renovations can assess the property and proposed works and coordinate the appropriate planning route.
Permitted development rights allow certain improvements and extensions to be carried out without making a full planning application, provided the proposed work complies with the relevant limitations and conditions.
Whether permitted development applies depends on factors including the type of property, previous extensions, dimensions and position of the proposed works and any local planning restrictions.
Where appropriate, we can assess whether your proposed extension or conversion may qualify and coordinate the necessary architectural and technical information.
Building Regulations are legal standards that set out how building work must be designed and constructed to ensure it is safe, structurally sound and energy efficient.
Most house extensions, loft conversions, garage conversions and structural alterations require Building Regulations approval, even where planning permission is not required.
Depending on the project, Building Regulations can cover areas including foundations and structural stability, insulation and energy efficiency, fire safety, ventilation, drainage, electrical installations and access.
Building Control will normally inspect the work at key stages during construction to confirm that it complies with the relevant requirements.
At Lewis Home Renovations, we can coordinate the Building Regulations and Building Control process as part of suitable extension and conversion projects in Beaconsfield, Buckinghamshire and surrounding areas, alongside architectural design, structural engineering and construction.
It is important to remember that planning permission and Building Regulations are separate: an extension may not need planning permission but can still require Building Regulations approval.
The construction period depends on the size and complexity of the extension and the amount of work being undertaken to the existing property.
Before construction can begin, sufficient time also needs to be allowed for architectural design, planning where required, structural engineering, Building Regulations, specification and project preparation.
We establish an appropriate programme once the scope, design and technical requirements of the project have been developed.
