How to choose an architect?
Unless your project is very simple, it makes sense to at least talk to an architect for advice before you get going. Generally, architects offer a wide range of services for projects with a substantial fee, but for a smaller fee, an architect can help you get the best out of your project in the early stages, regardless of size and whether they are needed later on.
Most architects offer one-off consultations and these can be incredibly useful. They will give you guidance on all aspects of your project from design and cost through to planning and construction. In a short space of time, you can very quickly gain thoughtful ideas and architectural insight to help you realise your project.
