Changes in how we live have created a need for different spaces. These include single person accommodation and accommodation for the elderly. Fortunately, skilful house extensions can add valuable space to help accommodate changing needs. What’s more, well-done home extensions can add value. So, how would an extension improve your property?

Extensions come in many forms
To suit clients’ needs, house extensions come in all shapes and sizes. These include vertical extensions to increase roof height. And lateral extensions that extend the front, side and rear of property.

Perhaps you have an idea, but need advice on its feasibility. If so, we’d be pleased to meet for a complimentary initial discussion about the options. From this, we can advise you on planning and costs before producing house extension plans or a design and build quotation.

Not all home extensions require planning permission. That’s because extending a house may be considered a permitted development that doesn’t require planning permission if it meets certain criteria – including the volume of space created and the relationship with neighbours’ properties. However, Building Regulations approval will generally be required and we can help with this.

Other types of house extension include bungalow extensions, which can require increasing the ridge height to gain additional space. Then there are terraced house extensions, which are generally to the rear and end of a terrace and often have potential for loft or basement conversion.

Residential and commercial extensions
Many clients also commission us to undertake building extensions to commercial and industrial property. Again, we’d be pleased to discuss your requirements.

We can achieve your extension using either contrasting or matching materials and styles. For instance, a small set back from the front elevation, showing a shadow line, can look attractive and emphasise development in the property’s history. This is usually the planners’ preferred option.

Of course, consideration should always be given to neighbours. This is particularly important because of the noise and general disturbance that may be caused during the project. Work adjoining a neighbour’s property may require a party wall agreement to avoid future legal action by the neighbour. And you’ll need to consider interruption of usage and disruption to activities within your home or commercial premises.
