"AK engineering did an excellent job in structural design of our custom modern house. Amir is very professional and responsive and worked closely with our architect and us. He made himself available for job site visits and questions and his design was efficient and cost effective."

"I've had the recent good fortune to work with Tolga on renovation projects in Los Angeles and Manhattan Beach for which I am the Architect. The success of renovation work relies heavily on collaborative and creative structural engineering in order to realize interior and exterior architecture goals. Tolga instinctively understood my design goals and in a very professional manner he crafted solutions to bring them to reality. Many thanks Tolga. I look forward to our next collaboration."

"My husband and I decided to completely redo our back garden.  After much research with other companies and viewing many ugly and blah ideas we chose G and L Design.  It was a very intensive project.  Giant ficus trees with very invasive roots had to come out, along with the roots.  Much concrete had to be removed.  Most of the old soil had to be replaced.  Most of the plants needed to be removed except for a few hydrangeas and roses.  We also had drainage problems along the side of the house which were affecting the integrity of the foundation.
G and L Design helped us develop a beautiful and comprehensive design and also addressed serious problems.  After doing an excellent and clean job of demo the fun part started.  Dee, the owner, took us to a stone yard where we found exactly what we wanted:  beautiful golden figured sandstone.  We wanted much hardscape for entertaining yet for the space to be lush at the same time.  Dee's excellent landscape architect Rick took us to nurseries and helped us decide on beautiful trees, shrubs, flowers and herbs.
Dee has permanent employees; he uses no day labor.  His workers are skilled.  Each large slab of stone had to be cut by hand.  It was put together like a beautiful puzzle.  The stone cutter was an artist.  It was a joy to watch him work.  We have an upper yard and a lower yard.  A beautiful stacked stone curving wall was created along with very pretty large half moon steps separating one area from the other.$
New drip irrigation systems and lighting were installed.  The drainage problems on the north side of the house were addressed.  The trees and plants are terrific.  Wherever your eye lands there is something lovely to see.
As the project progressed we obviously ran into some challenges but Dee always had a solution.  When I wanted to make some changes there was not a problem.
We are so happy with this fabulous addition to our home we are using Dee to redo the front of the house next.  If you're looking for a fair company and talented people look no further than G and L Design."

"Let me tell you about Amir he is a stand up and honest guy!! When all architect companies wanted to take me for thousands of dollars Amir instead gave me the tools (knowledge) of what needed to be done to get the site and floor plan done for the city. You don’t meet many business people that will give you honest free advice so Amir is greatly I meant greatly appreciated for his assistance and guidance in getting my site and floor plan completed for the city. Will definitely work with Amir again!!!!"

"I am a homeowner who did my own home remodeling architectural design. Even though I had architect degree, but I had never done any project in Los Angeles. As everybody knows, Building and Safety has tons of regulations to follow, which made the permitting process especially difficult. I was so lucky to work with David, my structural engineer, who is very sharp, knowledgeable and hardworking. Not only did he deliver his structural design on time but also he guided me through with all details of my architectural plan. He is very responsive and generous about sharing his knowledge. It was such a surprise when David got me the permit over the counter from the city office with only one attempt, which expedited my remodeling project timeline for at least two months. Definitely recommended!!"

"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."
