House Extension Planning

A house extension is a fantastic way to transform your home and enjoyment of a property by creating additional floor space withouth needing to move. Blackrock can help you with architectural floor plans. We would advise starting the process with a designer as opposed to a 'specialist contractor' so we can ensure that the extension architecture meets your needs as the end-user and not the contractor's preferences.

As well as providing extension planning, we have a considerable amount of onsite practical knowledge along with an understanding of build costs and construction methods. Through providing architectural floor plans, we have built up an excellent professional and construction based team around us, to help you achieve the highest standard on time and on budget.
