Architects questions, answered by experts

Consulting the architect of your house is not the best way to determine when it was built. Many homes are built by developers or builders, so there may not be a specific architect to track down—especially if you have a very old house. Instead, it’s best to rely on local government records.

In most cases, you should get an architect before you hire a builder. An architect will be the one to draw up formal plans for your project, including guidelines and even material lists for your builder to follow during construction. Many architects can even help you find builders, choose one for your project, and negotiate prices. Some are also willing to act as project managers throughout the process, working closely with a builder from start to finish.

In most cases, you should hire a draftsperson for simpler projects like minor home renovations, and you should hire an architect for new construction, structural changes to your home, and large home add-ons. If you’re working on a larger project that demands an architect or structural engineer, your professional will often have a draftsperson on staff and include their services in your estimate.

Some homes, like those with flat roofs, may not have eaves at all. Some contemporary-style homes also lack eaves, although many may have abbreviated eaves to divert water and protect the walls and foundation. Homes without eaves often have specific types of gutters affixed directly to the edge of the roof to provide adequate drainage.

A home elevator is a fantastic way to improve your home’s accessibility. Elevators allow anyone, even those who use wheelchairs or walkers, to safely move between floors within your home.

Dumbwaiters may allow you to move items up and down floors, and stair lifts can move people up and down, but elevators are the best option if you need space for people, their belongings, and/or mobility aids such as wheelchairs.

That said, home elevators cost more than other options, such as stair lifts. Consider your needs and your budget when deciding the best way to make your home more accessible to a person with a disability or a person who is aging in place.
