Double Storey Extensions

Why you should build a Double Storey Extension

Double storey extensions make for cost-effective, space-enhancing additions – and if you get yours right, it might make more sense to build one than move to a bigger house.

Double storey extensions, executed well, are a truly cost-effective alternative to moving house when you’re ready to seriously size up. They can add valuable living space but extra sleep space too. Plus, double storey extensions will remedy interiors that are not fit for contemporary life – a lack of bathrooms to balance bedrooms upstairs and, on the ground floor, a layout that gives you a poor connection to the garden, a cramped kitchen, or closed-off rooms where a more open-plan arrangement would be preferable.

Creating new rooms upstairs and down that fully integrate into your home is the key to a successful double storey extension. The principal rooms of your home should be accessible from the main hall or circulation space in an open-plan layout, as well as from the landing. Rooms or zones with related uses – like the kitchen and the dining space – work best grouped next to each other.

Finally, a two storey extension is a cost effective option, giving you more square footage for your buck than a single storey extension, and allowing you to transform the look and feel of both upstairs and down. Perfect for small homes and growing families, it's the easiest way to increase living space and add an extra bedroom.

When all the costs of upscaling and upheaval are considered, it is understandable that more and more people are choosing to stay put and extend their existing properties, often saving time and money in the process.

Double storey extensions are a great way of gaining more space for the family, with open-plan living and rooms that better connect home and garden increasingly popular.
