About Us

Osborne delivers. Every time. Through disciplined project management, cutting-edge technology, and experience in all aspects of construction, Osborne has built custom homes of every size and complexity since Graham first opened his doors in 2004. Osborne is a full-service builder and remodeler of high-end homes throughout the Los Angeles area.  

Osborne takes on projects that other builders cannot. For over ten years, we’ve been finding creative solutions to the most complex construction projects. We’re specialists in hillside construction and understand the engineering and logistical requirements needed to get the job done. From conception to completion, we’ll handle all your building needs, whether you’re building from the ground up or executing an extensive remodel. 

At Osborne, finding the right fit is paramount. We carefully evaluate each employee, specialist, and vendor before working with them. We value long-term business. Graham and Greg have known each other for over 30 years, having met in high school in Lake Tahoe’s Incline Village.  When you know and trust the people you work with, it’s easier to get every detail right, from design to delivery.  It’s our job to use our skills, our experience, our staff, and our network to transform your dreams and visions into the home you’ve envisioned for your future, for your family.  We believe that each custom home we build uniquely expresses the dreams and visions of its owners.       


"Clients place their trust in us – to be a part of building their home. I have tremendous respect for that and I take that responsibility very seriously.”

Graham found his calling, building, when he was a high school senior remodeling the family home in his native Lake Tahoe. Four years later, Graham was armed with an engineering degree from the University of Nevada at Reno and learning the building business while working for local contractors. In 2004, he moved to Southern California and obtained his General Contractor license. When he realized his lifelong dream and started Osborne Building, he brought four key tenets to the Osborne approach:  1. Listen to the client. 2. Deliver what we promise. 3. Stay on time and within budget.   4. Treat each home like it’s your own.  


“I love building. I love delivering the final product to our clients. I got into building because I love its creative aspects, and solving the challenges that emerge during construction.”

For over 15 years, Greg has called upon his personal background in construction finance and complex building methods to develop homes throughout California and Nevada. A true master of creating a plan and following it through to completion, there is no aspect of real estate and construction that Greg does not understand. Greg has developed a unique ability to connect with the needs of his clients and create efficient, effective teams that deliver. Greg’s attention to detail keeps Osborne’s projects on target and running smoothly.

The work was a performed timely and with the utmost respect and care for my property and needs, both financial and personal. The attention to detail and professionalism was impressive. I highly recommend Osborne Building Corp. to colleagues, friends and acquaintances because I am confident they will not be disappointed.

On the night before New Year’s Eve, after a long day at work, I walked into our new home to live. Words cannot describe the joy I felt. And to make it even better a bottle of Dom Perignon was waiting for me!!! ( Thank you for the wonderful gift basket). My joy was only surpassed by that of Julia and Alice’s. I don’t think I’ve ever seen two happier little girls. They love the house and they especially LOVE their new rooms.

Throughout the duration of this project your honesty, integrity and guidance never wavered. And you ought to be given some kind of medal for your patience!!! The end result of course is “the greatest house in the world”!!!

Thank you, thank you, thank you from the bottom of our hearts, for caring so much about your craft, and doing a truly outstanding job at building our dream home.

Graham was my contractor for a highly complex, risky and innovative redevelopment of my hillside property. It was such an unusually complicated job that a number of contractors that I initially interviewed were too nervous to work on the project. I liked Graham the moment I met him. My instincts told me that he was honest, bright, and professional. I told him at the outset that I would back his decisions to the hilt. I have never had cause to regret that. The redevelopment was fraught with complex challenges at every turn. I am proud to say that throughout the project my relations with Graham remained excellent and that his calm professionalism ( and that of his very pleasant staff) made the world of difference.I would estimate the sales price of my house when we started at below $2m. The house was simply falling apart. I spent $1.3m on the project and it is now worth about $6.3m.

Graham’s contribution to that increase in value was not just a question of following architectural schematics but with his own highly creative input that gave me more added value than had I chosen a lesser contractor. Graham does not cut corners. He’s not the cheapest and not the most expensive. His value lies in his unrelenting professionalism, honesty and calm demeanor.
I liked him when I started and despite all the very frustrating challenges I liked him when we finished. He really delivered and I would recommend him highly to anyone.

We have employed Osborne Building Corporation to construct our new home. We are 85% complete and on schedule. We’d highly recommend them. They are extremely efficient and thorough. They are very helpful with advising us and pointing out what may or may not work. They have given us the opportunity to see mock ups when visualizing just wasn’t enough. This way we would be satisfied with our decisions in the end. They are always available to answer questions, and quick to solve any problems that may arise. Definitely would recommend this company. Besides, they’re a bunch of really nice guys!

I have had the privilege of being a customer of Graham Osborne Building Corporation throughout the remodel of my Manhattan Beach home. Graham has proved to be a bright and creative contractor. I had very high expectations for the remodel from the start and he never failed to meet those. Graham consistently followed up with me on all requests and went above and beyond what I asked of him. He truly cares about his customer’s satisfaction with his work and continues to prove that even after the job is finished. Still today, Osborne Building is there to assist me with any repairs or questions I may have about their work. It is my pleasure to recommend OBC. I know that you will be as pleased with their work as I have been.
