You would usually need a relevant BTEC HND or degree – courses which include practical skills as well as creative design would be most useful. You could complete a specific furniture design degree, however, subjects like 3-D design, spatial design, furniture technology or product design are also relevant.
You would need to put together a portfolio of your design work that you can take along to interviews for courses and jobs.
Because the design industry is very competitive, any work experience you gain will give you an advantage when it comes to getting a job. It is worth researching companies whose products match your style, and making speculative approaches.
Entering competitions, exhibitions and shows may also be a good way of getting yourself noticed by employers.
If you intend to become self-employed, you can develop practical skills such as upholstery and carpentry on a wide range of courses offered by local colleges.
The crafts officer of your local regional arts board may be able to advise on studio availability and possible sources of funding - see the Arts Council website for contact details.
