Whether you're upgrading an existing structure or building from the ground up, Peter T. Erdelyi & Associates, Inc has the expertise to oversee your project through completion. We have designed more than 10,000 structures in the Los Angeles area over the past four decades; from apartment buildings to new single family homes to additions and remodels both for residential and commercial clients. Our team of professional engineers, drafters, expeditors and project staff will deliver plans that withstand the test of time.

"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

At Saylor Design Studio, I uphold a standard characterized by fairness, honesty, and accountability. My design approach involves working closely with clients to understand their unique needs, preferences, and lifestyle, ensuring that every design reflects their individuality. As a Custom Home Designer and a member of the American Institute of Building Design, I specialize in residential designs for additions, remodels, and new homes. I have over three decades of experience and have successfully designed over 700 projects. Additionally, I have an extensive background as a Set Designer and am a member of the Art Directors Guild and have completed over 70 film and television projects. My knowledge of construction methods, materials, and building codes allows me to provide accurate and detailed construction documents for contractors and consultants. This gives me a distinctive design perspective unmatched by others.

"I have known Steven for almost twenty-five years, we have worked together on various projects in the Film/Television industry. Steven is a good designer who is versed in many styles and has a full knowledge of period details. He has a sound understanding of architecture and knows how to create useful and attractive spaces; heâ s also a genius when it comes to problem-solving. Heâ s up to date on all available materials and how best to use them. Steven has a strong work ethic and is very conscientious, and his sense of humor and light disposition puts anyone at ease; he gets along well with people. Recently, I had Steven draw up a ramp and a flight of stairs for the front entrance to our condo building, and as expected, he did a splendid job. We worked on the design together, and he prepared the working drawings and documentation. Then, he saw it through the local authorities here in Redondo Beach. I highly recommend him to solve any design requirements you might have."

Architects questions, answered by experts

While classic Palm Springs architecture in the Palm Springs area will naturally cost more due to the high cost of living, prices across the rest of the country will vary. Remember that older homes, including those built before 1970, will cost more to renovate due to updated building codes—something to keep in mind when considering the upfront cost of the house.

Depending on project scope, complexity, and building size, architectural services for businesses typically cost between $2,000 and $50,000. Fees can be structured as hourly rates, fixed pricing, or a percentage of total construction costs.

Yes, integrating sustainable practices and energy efficiency into plans is common.

The process typically takes 2-6 weeks, depending on the project size and level of customization.

You likely need to hire an architect for your new house design and build, unless you have the design skills and experience with building regulations and standards needed to get your plans approved. If you are able to meet the design requirements, you can hire a draftsperson to create the blueprints for the builders to follow.
