Maria Luisa,

Thank you for all the details and hidden services you provide.  You are not only and exquisite design architect, you are incredible artist and woman.

Maria Luisa,

I was blessed to have you as my architect for my bathroom and kitchen remodel. You really went above and beyond to help me. Starting with your flawless plans that breezed through the building department approval process! I am especially grateful for your insistence on getting me a better contractor bid. You were a great negotiator!

I can’t say enough about the experience. I don’t know what I would have done without your advice and attention to detail. You were awesome!!

Thank you again and I hope you enjoy this little token of my appreciation.

Dealing with the Building Department - We can help you sail through it!

As Miami architects, residents for many years, we bring extensive knowledge of the construction industry, forging good relationships and an excellent reputation with local building departments. Our familiarity with this area, the various departments and disciplines, can help navigate your plans through the process quickly.

Unlike many Miami architecture firms, we only send completed drawings to the building department.  Then, we carefully follow up with the entire permitting process. This means we actually go to the building department and meet with the officials, if necessary, unlike other firms. . We are always available to walk you through the process and let you know what to expect each step of the way. 

Dealing with Contractors We can be fierce negotiators for you

We help you select the best contractor for the project, often through multiple bids or a negotiated process.  We can help you determine the best written contract for the project.  We consistently negotiate the most cost-effective deals for our clients — while still keeping our friendships in the construction industry!

Check out our website, then call, write or text us.

We invite you to spend some time on our website and to call at (305) 552-5465 or write to us at MLC@UnitedArchs.com or text us at (305) 439-7898.  There is never a charge for the initial consultation, if you own the property.
