What is a granny flat?

Granny Flats are commonly known as Accessory Dwelling Units additions or ADUs.  ADU additions on your property may or may not be attached to your home or garage, or may be a complete garage remodel into a living space.  Often if the property is larger enough, they are stand-alone structures. Basically you can have a studio apartment within your property.  This is perfect for those looking to have a rental on the property, or a place for grandparents or other family to stay.

Customer Reviews

We are military and just moved to San Diego, and this is also our first home, so the process was a bit scary, because we wanted everything to be perfect.They were completed in 5 days and left no mess and created no problems. These guys were consummate processionals, and there's not enough words that I could type into Yelp to talk about how great this experience was.
The star of the show was Patricio! He spent a long time talking with us to understand the aesthetic we were going for and ways that we could get our dream backyard at an affordable price. We were happy with the crew he hired as well. They were professional, timely, and clean. We are in love with our backyard and so happy that Patricio could see our vision.
We had pavers, stairs, a deck, sod, repair of our existing pavers, cleanup of our existing pavers, and sprinklers repairs and installed from a previous pool build. They were not the lowest contract bid but you definitely get what you pay for. They were happy to accommodate any minor changes without having to negotiate every little thing.
My wife and I had reached out to several different companies for quotes to redo our absolute mess of a front yard. After talking with several and receiving a number of quotes, we decided to go with Designs4You, and couldn't be happier with our decision.
I'm extremely satisfied with the job D4U did remodeling my backyard! The big one was the backyard, and D4U did a marvelous job transforming it into a cool and useable space. This project included: demo, installation of a retaining wall, concrete pavers, a DG area for my dog, stucco, and an outdoor kitchen with grill and pizza oven.
