"I was looking through Angie's list to hire an Architect and noticed "Mark Anderson Architects" was open (it was 7:30pm). Decided to give a call and I was expecting a receptionist to answer, but it was Mark himself. Talked to him about the project I had in mind and he gave me all the information over the phone. He was very straight forward. Thanks for your time Mark."

"We had an excellent experience working with Robert Anthony from start to finish. They were professional, responsive, and incredibly detail-oriented throughout our kitchen remodel. His team completed our renovation on time, kept the workspace clean, and communicated with us every step of the way. The quality of the craftsmanship exceeded our expectations, and you can truly tell they take pride in their work.

"Firmin is a pleasure to work with. He is professional, responsive, and he helped me immensely by creating a set of drawings for a condo renovation. He came over to my house, discussed the project with me and made me realize that my design needed some adjustments. I was very grateful for this because I think I would not have liked it otherwise. He created the drawings on schedule and delivered by the agreed upon deadline. I would hire Senga Architects again without thinking twice."

Architects FAQs, answered by experts

Building a house without blueprints is not advised. It will prevent you from obtaining necessary building permits and meeting building codes and is likely to result in shoddy construction and unsafe living conditions. Detailed blueprints ensure that a house is built to exact specifications and is constructed safely and structurally stable.

An architect plans and designs new construction and alteration projects. They often provide sketches for homes, office buildings, shopping malls, and other structures.

Cathedral ceilings make a statement in your home, but at the cost of your attic space. Normal attics are wide open, which allows warm air to move around and exit your home. Because of this, cathedral ceilings make your home less energy efficient and put your ceiling at risk of venting issues if you’re not careful. They also reduce your attic storage space, potentially cause an echo, and even make it harder to change a light bulb.

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.

In most cases, you don't need to hire an architect for a garage conversion. Your garage conversion contractor should have the skills and experience to help create your desired design. However, if the scope of the conversion is large and complex, and your budget allows, it's smart to hire an architect to oversee the design.
