Delta Builders Ltd is one of London�s leading design and build companies, with years of experience delivering a wide range of home extensions.
Looking to transform your home with a bright, stylish, and practical open-plan living space? A side return kitchen extension could be the perfect solution.
A side return extension is built along the rear and side of a property, typically in the narrow space between neighbouring houses.
By making efficient use of existing space, side return extensions significantly improve layout and functionality while preserving garden space.
We take pride in our client-focused approach, ensuring every stage of the build is shaped around your needs.
This can include bi-fold doors, glazed roofs, or floor-to-ceiling windows to maximise natural light and create a bright, open environment.
The cost of a side return extension depends on size, roof design, and property type.
As a guide, a medium-sized side return extension typically costs around �68,000, including construction, plumbing, electrical work, glazing, and VAT.
Our team provides expert guidance on planning applications, permitted development rights, and building regulations approval.
