You might think having a professional designer handle the planning process for your extension would be an unnecessary expense, but it can actually save you money in the end. While having a reliable team of builders carry out the project is just as important, the ability to plan the extension in detail – both from a timing, materials and costings point of view – can pay off in the long run.

Before I began David Haworth Architectural Design, I had already encountered the problems of homeowners neglecting the design process at first hand, with builders often giving unrealistic quotes, overrunning completion dates, and not sticking to agreed parameters for extensions.

By mapping out exactly what you want to do, how you want to do it and the materials you will use, you already have a template for a successful project. The designer can act as your go-between as the work is being done, fielding any questions the construction team might have relating to his plans.

You can also call on a designer to recommend trusted subcontractors that you might want to seek a quote from. An existing relationship between the designer and those carrying out the work is a ready made advantage before you begin, and can make for a smooth operation.

Professional designers usually also have a fantastic attention to detail that there is no substitute for. When you come to see the end result, you might be thankful that you called upon a designer to specify how every part of your extension should be built, to the millimetre. This approach leaves no room for error.

Finally, you should note that a home design professional can guide you through some of the legislative and planning considerations which often spring up with an extension, making sure you cross the Ts and dot the Is as part of the process.
