What is a wraparound extension?
Wraparound house extension combines both side return and rear extension to create an L-shaped space. If you are looking to utilise the kitchen or dining/living areas, create an additional utility room, ground floor shower room and maybe a boot room then this is the best way forward.
Wraparound extensions add an amazing amount of space too, anything from 15m2 to 60m2. they are ideal for ground floor flats, houses that have an outrigger, semi detached houses that have unused space to the side or even an existing garage at the side of the house. In some circumstances terraced properties can benefit from a wraparound extension too for example an end of terraced property.
Wraparound extensions are very popular with homeowners looking to increase the footprint of their homes and even to transform the existing layout so that it is more complimentary to modern family life, allowing for the addition of a large kitchen and more open plan family space. These extensions are transformative on suitable properties due to the size they offer and the flexibility of the layout maximising wasted areas which will be utilised to create a generous ground floor space.

Will I need planning permission for my wraparound home extension?
A wraparound rear house extension will most likely require full planning permission. At LCCL Construction we can help you with the full design and build of your wraparound extension in one convenient package. Our architect will visit your property and produce existing vs proposed drawings so that we can submit a planning application to your local planning authority. We will also take care of structural drawings, Party Wall Agreements and of course complete the build stages of your extension project. If you are planning on building to the side only and to the rear only without the L connection then this may not require planning permission it could fall under your homeowner permitted development rights.

Is my house suitable for a wraparound extension?
The wraparound extension can be created on terraced houses, end of terraced houses, semi detached houses or detached houses including Period style properties, Edwardian, Victorian or modern homes that have space to the side of the ground floor outrigger/kitchen or even to infil alongside an existing rear extension that is not full width.
What kind of layout can I expect internally?
Internally the wraparaound house extension can have a large kitchen with a kitchen island, underfloor heating, upgraded electrical and plumbing solutions. Typically homeowners are trying to achieve a spacious open plan layout to the rear of the wraparound house extension with additional rooms to the side of the extension, such as utility room and downstairs bathroom or bootroom. Clever design will improve levels of natural light with velux skylights, or on a flat roof lanterns or flat skylights. Bifold, Crittal or sliding doors add more light and create a view of the garden with increased glazing to the rear of the extension. As well as the large open plan kitchen living area other popular additions to a wraparound extension include the installation of an understairs wc and construction of a utility room or utility cupboard to house all the laundry equipment out of the way.
What type of roof can I have on my wraparound house extension?
Features of a wraparound house extension with a pitched roof - the pitched roof would be covered in roof tiles such as clay, concrete or slate tiles, velux lights can be installed to the pitched roof, at the rear of the wall there can be various types of glazing but the most common are bi-fold doors, sliding doors, crittall or french doors. The finish of the exterior walls comes in render, brick finish or cladding such as zinc clad. In addition a new patio can be added towards the rear of the property to create an outdoor seating and dining area outside the new extension.
Wraparound house extension with flat roof - the roof is all on one level with only a very slight pitch to prevent water pooling. There are many options for flat roof coverings such as mineral felt, GRP, torch on felt, EPDM, fibreglass or GRP to name a few. In terms of glazing features include options similar to above except the flat roof would have flat roof skylight or lantern added instead of velux windows.
How much value will a wraparound extension add to my home?
A wraparound extension brings many benefits to the house and naturally homeowners are keen to find out if the work completed adds value to the property. According to The Times Money Mentor (source https://www.thetimes.co.uk/money-mentor/article/best-ways-add-value-home/) building a side or rear extension can add around 15%, with an additional bathroom adding around an additional 3% to the value of the existing house.
