If you’re thinking about a potential home extension, we are able to assess your Kingston home for its suitability in terms of what you have in mind for the project. Throughout this process, we will consider your budget, the area, neighbours’ houses and a timetable. The idea behind this is to assist with adding value to your property by looking at possible planning restrictions, what your neighbours think, and consider what deadlines we can work to for your building project. We will explore the multiple options you have for house extensions, and offer any necessary advice you may need, for example, with whether you need to gain any planning permission.

Loft Conversions

We also offer our expertise for loft conversion services throughout Kingston, whatever type of property and conversion you desire. A loft conversion is one of the simplest methods for gaining additional space in your home. It will also add value to your property, which is a benefit should you want to sell in the future.  We will be able to decide whether your Kingston loft is suitable for a loft conversion by considering a range of factors. These include head height, pitch angle, any obstacles, the age of the structure and the end shape (whether gable/straight, or hipped/angled). When you select us for your loft conversion project, you will obtain a bespoke service which will enable you to move that one step closer to your dream home with a wonderful loft conversion.
