Turn Unused Space Into Something That Works
Got a garage full of storage bins? An attic collecting dust? A basement with potential?
At Mega Development, we specialize in transforming underused areas into livable, beautiful spaces — without adding a single square foot to your home’s footprint.
Whether you need a guest suite, home office, rental unit, or hobby room, we’ll help you convert what you already have into something that adds real value and everyday function.
What We Convert
We help Los Angeles homeowners get more out of their homes by reimagining:
- Garages – Converted into home gyms, offices, guest suites, or full studios
- Basements – Finished into media rooms, playrooms, rental spaces, or multi-use zones
- Attics – Transformed into quiet workspaces, loft bedrooms, or storage-smart solutions
We take care of the design, code requirements, permits, and construction — so the end result doesn’t just look good, it works right and serve your needs.

How It Works

Walkthrough & Assessment
We check your space for height clearance, access, utilities, and structural feasibility. Then we talk through how you want to use it — and what it’ll take to get there.

Layout & Design
Our team designs a layout that makes the most of the existing structure, adds light, improves flow, and meets building codes. ✦ Need a visual before you commit? 3D design options are available so you can preview the space before construction starts.

Permitting & Planning
We handle all city approvals, engineering, and code compliance. Whether it’s fire egress, insulation upgrades, or electrical changes — we’ve got it covered.

Prep, Demo & Utilities
We open up the space, install or upgrade plumbing/electrical/HVAC as needed, and prep for framing, insulation, and finish work.

Construction & Finishes
We build it out with attention to detail — flooring, drywall, paint, lighting, cabinetry, and final trim. Everything is installed to match the style and quality of the rest of your home.

Final Walkthrough
We do a full quality check with you, confirm everything is working properly, and hand over a clean, ready-to-use space.
