Modern HQ Office Design

I need a comprehensive design for a 150 square meter modern style headquarters office. The office should include:

- 1 large meeting room
- 3 General manager offices
- 3 function manager offices
- An open area with at least 15 desks
- 1 luxury lounge aimed at client meetings
- 1 Coffee area
- 2 toilets

The open area should feature an open desk layout, as opposed to cubicles. The lounge should be designed with a modern touch to cater to clients.

Ideal skills for this project include:
- Extensive experience in modern office design
- Ability to create a functional yet stylish workspace
- Familiarity with designing client-focused spaces
- Proficiency in planning open desk layouts
