Planning to create more space without moving? A&G Construction London delivers premium home extensions designed around the way you live. With many years of experience across London, Essex, and Hertfordshire, we provide a managed, design-and-build service focused on quality workmanship, compliance, and a smooth project experience from survey to handover.

• Rear extensions – ideal for opening up the back of your home and creating larger kitchen–diner living spaces.

• Side-return extensions – perfect for London terraced properties where unused alley space can become a new internal area.

• Wrap-around extensions – combine rear and side-return extensions for a full ground-floor transformation.

• Double-storey extensions – add new bedrooms, bathrooms, or living space on upper levels while improving ground-floor layout.

• Kitchen & living reconfigurations – structural steel installation, layouts, glazing, and premium finishes.

• Structural works – RSJs, load-bearing removals, foundations, drainage, and insulation completed to specification.
