Residential Design questions, answered by experts

Building a home office addition can take three to four months to complete, while renovating an existing room into a home office may take two to six weeks, depending on the extent of the renovations. Your project’s timeline will depend on permit approvals, material availability, site prep, construction delays, and other factors. Your general contractor can keep you up-to-date on estimated completion times.

An in-law suite is a private living area on or attached to a single-family home that acts as separate living quarters for family members. It should include a sleeping area and full bathroom, though most also include a small kitchen or kitchenette and a living area. Larger suites may also have space for an office or laundry room, which can add utility and increase independence for guests and residents.

You can design your own closet, but it’s usually better to hire a professional to do the work for you. Not only will you get years of design experience to guide you toward the right layout and material choices, but you’ll also only pay slightly more hiring a professional than you would creating your own plans and hiring a carpenter. A high-quality closet designer can provide insight into how to lay out your closet, and they may be able to find you a good deal on the carpentry or complete the work using an affordable, in-house team.

Costs range from $50 to $200 per hour or $2,000 to $10,000 per project, depending on scope and experience.

For a garage to count as living space—and towards your home’s total square footage—it needs to be attached to the rest of your home and have permanent finishings such as proper insulation, finished walls and ceilings, and adequate ventilation. It also needs to be livable at all times of the year, so it should be heated if it gets cold in the winter and cooled for hot summers.
