[03 About]
Creative minds. Real project. Real humans.


The name Grayscale Concept is a reflection of our design philosophy. Grayscale refers to a range of shades between black and white, and it represents the idea of balance and harmony. Our approach to design is to create spaces that balance form and function, light and dark, and every other element that goes into creating a beautiful and functional home.
We’re not just here to create beautiful spaces, we’re here to make them functional and meaningful. Whether for rental income or additional living, we help clients bring their vision to life through thoughtful design, strategic planning, and a seamless permitting process.
[04 FAQ]
Smarter decisions start with clear answers.
How long does a typical project take?
The timeline depends on the project scope and the city’s permitting process. For example, a typical ADU project in Garden Grove, CA may take 1.5 to 3 months for permit issuance, while in Midway City, CA, it can take 4–5 months due to longer city review times.
What if I don’t know exactly what I need?
No problem. We’ll help you figure it out. Whether it’s a quick call or a deeper discovery session, we’ll guide you through it.
How do payments work?
For projects, we usually split payments into 2 or 3 milestones. For monthly plans, billing is done upfront each month. Everything is clear and agreed upon before we start.
