Two Focuses. Zero Compromises.
Most contractors do everything badly. We chose to master two — ground-up New Construction and ADU — so your project gets specialist-level expertise, not generalist guesswork.
Hear It From a Real Builder — On-Site.
No stock footage. No actors. Our founder, on a New Construction job in Altadena — explaining what makes an Arka build different and why honest pricing isn't just a marketing slogan to us.
Build Your Custom Home
From Dirt to Keys.
Arka is an end-to-end custom home builder. One team handles architectural design, engineering, permits, site work, framing, systems, finishes, and final inspection — so your build stays coordinated, on schedule, and on budget.

Rental Income to Your Property.
LA's 2024 housing rules make ADUs the highest-ROI upgrade most homeowners can make. We design, permit, and build detached, attached, and garage-conversion ADUs — and hand you a property worth $150k–$250k more the day it's done.
Figures are representative LA-market averages. Your quote will be based on your site, lot, city, and finishes.
The Honest Pricing Guarantee
We've seen too many LA homeowners burned by lowball quotes that balloon mid-project. So we made a promise:
- Every line item, itemized — materials, labor, permits, allowances
- Zero surprise change orders. If we missed it, we eat it.
- Fixed-price contracts — not "cost-plus" gotchas
- Weekly progress reports with photos and spend-to-date
