WHO CAN DESIGN YOUR EXTENSION?

If you’re planning to work with a professional, seek recommendations from neighbours and friends and browse completed projects online to find the designer that best suits your style. Take into account finishing materials as this may impact on whether you need to work with a specialist. For instance, if you want an oak frame structure, then you’re best to choose a firm that’s experienced with this construction method.

Architects & designers Deciding to come up with your own extension plans without help from a professional might seem like a good cost-cutting exercise, but don’t underestimate the skills and knowledge a designer can offer. There’s flexibility in terms of how much you want to involve them – for instance, they can just draw up the plans or apply to planning on your behalf, or source contractors and project manage, if that’s something they offer. “Create a brief your designer can work with, so they can efficiently balance your requirements,” says Nimi Attanayake. “Collaborate with your architect and contribute your ideas.” Visit the Royal Institute of British Architect’s (RIBA) website for a list of chartered professionals in your area.

Specialist companies Design and build firms can offer a hassle-free route to an extension. They can provide design, project management and builders, so as much or as little as you like is taken care of. “One advantage of such firms is that costs are provided in advance, so you never make decisions without knowing a price tag,” explains Lui Rocca.
