EXTENSIONS & CONVERSIONS

Wrap Around Extensions

Transform your home with expansive L-shaped extensions that integrate side and rear space for better living and working.

About our wrap around extensions service

A wrap around extension is one of the most transformative structural changes you can make to a property. By merging the concepts of side and rear extensions, this L-shaped addition creates a vast amount of new floor space that can completely redefine how a building functions. For homeowners, it is the primary solution for achieving a large, open-plan kitchen and dining area that flows naturally into the garden. For commercial clients, it provides the necessary square footage to expand retail floors or office layouts. These projects are more complex than standard house extensions because they often require significant structural steelwork to support the corner of the existing building where two external walls are removed. At Design N Build, we handle the intricacies of these builds, from initial architectural drawings and navigating planning hurdles to the final handover of a high-specification living or working space. Whether you are considering a single or double storey extension, our approach ensures the new structure integrates perfectly with your current property layout.

What's included

  • Architectural Planning

    Detailed blueprints that maximise your available land while ensuring the new structure complements the original architecture of your property.

  • Structural Engineering

    Expert calculations to ensure the safety of your home during the removal of load-bearing walls and the installation of complex steel frames.

  • Comprehensive Build Phase

    Full construction services including excavation, brickwork, and roofing, managed by experienced site foremen to ensure high-quality standards.

  • Glazing and Roofing Solutions

    Integration of modern bifold doors, roof lanterns, or floor-to-ceiling glazing to ensure your new extension is flooded with natural light.

  • Full Internal Fit-Out

    Management of all plumbing and electrical requirements, including underfloor heating and bespoke lighting schemes for the new area.

    By connecting the side and rear of your property, you create an expansive open-plan layout that accommodates modern living, dining, and cooking zones effortlessly.

Frequently asked questions

Do I need planning permission for a wrap around extension?

A wrap around extension typically requires a full planning application because it alters the footprint on two sides of the building. Unlike simple rear extensions, they rarely fall under Permitted Development rights. We manage the entire application process, ensuring designs meet local authority guidelines and building regulations.

How long does the construction process take?

On average, the construction phase for a wrap around extension takes between 14 to 20 weeks. This timeline accounts for structural excavations, steelwork installation, roofing, and internal finishes. However, the total duration depends on the complexity of the project and if you are adding a double storey element.

Can you build wrap around extensions for commercial properties?

Yes, wrap around extensions are highly effective for commercial properties such as clinics, nurseries, or small offices. They allow businesses to expand their operational floor space significantly without the high costs and disruption associated with relocating to new premises.

How much does a wrap around extension cost compared to a side extension?

Costs are influenced by the size of the footprint, the type of glazing chosen, and any internal reconfiguration required. Because these projects involve removing two external walls, significant structural steel is needed. We provide detailed, fixed-price quotes after reviewing your specific site requirements and architectural plans.

Can we remain in the house during the build?

Living on-site is possible but can be challenging due to the scale of the work. The project involves major structural changes and periods where the rear of the house is open to the elements. We work closely with you to create a schedule that minimises disruption to your daily routine.
