Extensions ( Double Storey )

A two storey extension project could be the perfect solution to transform your home. It is the best way to increase the living space and bedroom accommodation at the same time. If you find that your home is too small, or you have a growing family, an extension like this could be the right solution for you.

It may also prove more cost-effective compared to buying a new house or building a single storey extension or outbuilding. A two-storey extension spreads the cost of the foundations and the roof – bringing down the average construction cost per square meter. The rear of a house is usually the best position to add a two-storey extension on a terraced house or semi-detached property.

Construction – Refurbishment & Renovation London, together with its partners, takes care of everything that has to be done from removing a throwing away old furniture, demolish and completely renovating apartments, houses, shops and offices, setting up the necessary installations, to assembling new furniture and final clean up.

If your property has a large outdoor area there may be the potential to extend over two storeys at the side. In some instances, an extension can wrap around multiple sides of a property. If there are restrictions regarding the roof height, you could still extend into the roof space to form a one-and-a-half-store extension. You could also dig down into the ground and build two storeys without affecting room height. This could result in a basement level or split-level design and can work well on a sloping site.

If needed, we can also take care of all the paperwork, besides the construction part, only to give the customer confidence and peace of mind. We can apply for the needed permissions and certification and also arrange council inspections. Depending on each case, you might need a planning permission, demolition permission, consent for the scheduled monument and other types of approval from the local authorities.

Construction – Refurbishment & Renovation London, together with our partners, can offer you the house extension you have been dreaming of. Who does not want to have more space and if your house can be extended, why not take advantage of this? Many would ask why not move into a new, bigger home? But when you have invested into your actual home and if it’s in a neighborhood and area that is convenient for you, buying a new home is out of the question. So you look for other solutions such as house extension.
