Samuele: A designer is like a tailor. If I want a new shirt tailored to fit, I will need a tailor who's able to take the right measurements and make an apparel which looks good on me.
As a client, I will need to tell my tailor what colour works best on me and what fabrics I like, details I want etc. These decisions will be made by me, not my tailor.
Similarly, a good designer must be able to understand the project's needs, client's brief, consider the locations - before he or she proposes the best-fit solution.
Designing is about providing the best solution for a problem, not purely creating something that the designer fancies.
What do you love / hate about being a designer?
Samuele: Designing is very tricky. There'll always be someone who loves your work; someone who hates it.
The best way to approach design is to avoid following trends and favouring personal choices. Instead, answer objective problems so that you can make your stakeholders happy... at least most of them.
The key element in Workplace Design is creating a comfortable environment. Inject some personality, but not overwhelm. Energise, but not to a point of making you tired after a long while. Curate a place that will make you feel... at home.
