house Extension
Whether it is for inspiration or practical help Revamp And Build can help you.
A new home extension is a fantastic and cost-effective way to increase the value of your home and, more importantly, can add more living space for you to appreciate.
A wonderful new kitchen, perhaps a home gym, or maybe a playroom for your children can all be achieved with a home extension. Let us not forget with more and more people working from home in 2021 – a home office must be a serious consideration.
Revamp And Build has a vast experience of carrying out extension works to a variety of classic and modern buildings.
We will work and listen to you initially to understand what you wish to achieve and then using these ideas we will design a tailor-made extension package for you, whatever your budget.
Home Extensions are limitless but here are some examples:
Single Storey Rear Extension Price £30,000 Upwards. (*)
Considering a single storey rear extension is a fantastic way to expand your living space and enhance the value and character of your home.
Ideal for families in need of extra room, these extensions can be tailored to your specific requirements.
This option is also one of the most spacious, providing maximum head height that makes the space feel more like an additional storey than a loft room.

Double Storey Extension Price £45,000 Upwards. (*)
Adding a double storey extension might seem like a bigger and more expensive project compared to a single storey one, but it’s often a more cost-effective way to create extra space in your home.
It can also be cheaper than moving to a new house when you need additional rooms for a growing family. Additionally, building an extension can significantly change the appearance of your home from the outside, so it’s crucial to carefully plan and design the right extension for your property.
This includes considering the planning and building regulation requirements as well as estimating the costs involved in building a two storey extension.

L Shaped-wrap around Extension Price £65,000 Upwards. (*)
A wraparound extension is built to wrap around the outside of an existing house, providing additional living space.
This type of extension usually combines a side infill extension that encloses the space to the side of a projecting outrigger, and a rear extension that encloses the space to the rear of the same outrigger. Together, these areas form an L-shape around the outrigger.
