Finding an architect on townhomes built 10 years ago

[Gino Picciola]

Hey bigger pockets!!! I am purchasing 3 lots in a townhome subdivision. The original builder lost it all. He built about 50 other townhomes in the development. He went bankrupt out of business before he was able to finish the development. I am now purchasing the remaining townhome lots allowing for a total of 17 units. I want to duplicate the exact townhomes that are currently there. What is my best option to do so? Find the architect or start over with a new one. Any advice would greatly be appreciated. Thanks!!
