Custom home design, photoreal 3D visualization, and permit-ready construction plans, for new builds, major remodels, additions, and everything in between.
Every project begins as a conversation - and ends as a set of drawings a builder can trust.
I am an independent architectural designer and drafter based in Los Angeles, with extensive experience collaborating with local builders, contractors, and homeowners throughout Southern and Northern California. I specialize in delivering a full range of services for new construction, custom homes, home additions, garage conversions, ADU projects, and more.
Every project begins by understanding how my clients live and what they want to achieve. Whether it's a new custom home, a major remodel, a home addition, a hillside residence, or an ADU, I develop coordinated construction drawings that are clear, complete, and tailored to the project. My goal is to make the design and permitting process as smooth and efficient as possible while delivering spaces that are both beautiful and practical.
From first sketch to city approval
Design & Concept
Every project begins with understanding your vision, your site, and the way you want to use the space. Existing conditions, local requirements, and site opportunities are carefully considered to develop a thoughtful layout that balances function, flow, and your goals.
Construction Plans
Complete, coordinated plan sets - site plans, floor plans, elevations, sections, and layouts - prepared for permit submission, with structural work by licensed California engineers.
3D Visualization
See your project take shape before construction begins. Photorealistic renderings reveal materials, light, scale, and atmosphere, helping you visualize the final result and make informed decisions with confidence.
Permit Coordination
Submittal, plan-check tracking, and revision management handled for you - so the project keeps moving while you don't chase city departments.
In their words
It is my pleasure to recommend the design services of Alexandra Sun, ISLD Plans and Design. Ms. Sun assisted me with plans and permits to build my ADU. She was easy to work with and returned calls within a few hours. Her long-standing relationships with LADBS were instrumental in shepherding my project through the challenging approval process. Even after I received my permits, she stayed in contact to make sure my project was going smoothly. I intend to use Ms. Sun’s services on another remodel I am planning.
I had a great experience working with Alexandra on multiple construction projects. She was always available to answer questions, provide guidance, and make sure everything stayed on track. The renderings she produced were consistently high quality and instrumental in helping visualize the final designs. I highly recommend Alexandra to anyone looking for a talented, reliable, and dedicated designer.
Let's design what's next.
Tell me about your lot, your building, or the idea you can't stop thinking about — and I'll tell you exactly how we get it drawn, approved, and built.
