Architects questions, answered by experts

Some architects include interior design in their portfolio of offerings, while some architectural firms employ interior designers to handle that aspect of home building projects or refer clients to interior designers they’ve worked with in the past. Ask a local architect whether they offer interior design services as well.

You can draw your own house plans using three-dimensional modeling software, but in most cases, you’ll need an architect to draw up the final plans. Architects understand local building regulations and requirements, so their plans will be necessary for getting permits approved, and they’ll also ensure your home is structurally sound. DIY house plans can be a good place to start to help visualize your project, but you should always defer to a professional before trying to proceed with the project.

When planning a new build, meet with an architect as your first step. Architects will often work with specific contractors and can ensure the contractor on your project is qualified and experienced to handle your build. Both the architect and the contractor should be involved with the project from the early stages, but the process may be smoother when you start with an architect.

As with most large-scale home renovation projects, you’ll need an architect to map out the exact layout and specs of your above-garage room, which is required in many municipalities. Some general contractors will serve as your architect, or they may bring on a residential architect to assist with the plans.

While possible for small projects, professional designers ensure compliance with building codes and structural integrity.
