STOP-Don’t go here….unless you want the best selection, no pressure, fair prices, fast service and professional installation. These guys do it all from slab selection to final installation so you are only dealing with one company who takes all responsibility for the entire process. Ask for Sam and get there soon before everyone finds out about them!

Found Extended Development in N. Hollywood through Google. Seb answered the phone the first time I called. This is the place to get this done!! Exactly what you need- one stop shop.My husband and I went to the shop, Seb helped us decide on the slab we wanted and what would look right in our kitchen, which was super helpful- he’s very knowledgeable and responsive. Extended Development was super fast, I can’t believe how quick it was from when we picked our slab to getting our countertops installed. The guys we quick and knew what they were doing, countertops look beautiful and they made sure everything was right. Can’t say enough that I’m so glad I found this place and would definitely recommend to friends and family.

Absolutely love my new quartz countertops! Very fast, reliable, and professional individuals to work with. Ever since we got our quartz countertops installed, we got so many compliments! I went to over 10+ stores and none of them had what i was looking for, except for this place. Highly recommended for anyone looking to remodel their kitchen/bathroom.

Amazing experience with these guys! We did a shower using bookmatched quartzite Patagonia. Difficult stone to work with but Sam and Seb were total pros, went through the layout on the computer before cutting, install was seamless. Came out perfect.

I was looking for white quartz countertops for my newly remodeled kitchen and after visiting several different warehouses I found this place online and gave them a call. Sam was kind enough to call me back and we decided to stop in. We toured the warehouse and found exactly what we liked and we’re thrilled with the prices of their slabs and even more so that they also did the fabrication. Seb came and measured the same day and within the week our countertops were installed. Their crew of workers were professional, efficient and took the time to clean everything before they left. The whole process was effortless! I highly recommend Sam and Seb! Their warehouse is filled with a variety of beautiful slabs and stone to choose from with great prices and fabrication services all in one! We’ll definitely use them again and without a doubt refer them to our friends and family, thank you!

I had been shopping for my backsplash and countertops and found this place on Google. I was looking for something unique and special and not the same run of the mill designs. When Sabo took me into his warehouse I was amazed with the selection he had. I immediately was gravitated to this gorgeous porcelain slab for my backsplash and a coordinating quartz for my countertops. Thank you Sabo for your patience and expertise. I would highly recommend your business. I’m extremely happy with my kitchen.
Ok where do I start these guys rocked the house literally. Check out the porcelain work they did on the fireplace, and Quartz countertop slabs it was a whole Kitchen and the bathroom vanities. The value of their work shows and it really enhanced this old out of style home into a modernized dream getaway.If you are hesitant to hire them don’t because i am a testimony for their work as you can see in the photos posted. They were fun to work with and made the transition smooth.

We visited over 15-20 different granite slabs and tile stores in Ventura County and Hollywood. Until we stopped at Extended Development and met Sebo he was very helpful and very knowledgeable he took the time to explain and show us different slabs. We will tell our friends and relative about this place they are great.

Great experience! Process was fast, without any glitches or multiple sales people to deal with. Purchased the stone and fabrication from one entity who delivered exactly as stated, unlike the hurdles at big box or membership stores. I would strongly recommend them to family, friends or neighbors. We chose the quartz pattern we liked and had the kitchen measured within the next two days. Three days later the counter tops were fabricated and installed. Installers were very professional and made sure to clean before leaving. Price for the quartz slabs, fabrication and installation was worth it. Best experience of this type ever. Will go back to them for other stone related services for sure.
