Attic Conversions

Attic Conversions Add Living Space to Existing Homes

Attic conversions make good economic sense in most existing homes. Attic conversions can be projects as simple as adding flooring for storage space or as complicated as adding a whole new suite of rooms, including bedrooms, bathrooms, studies, or game rooms.

Thorough planning is the first and most important step in attic conversions. Some factors the homeowner should take into account when planning an attic conversion include whether the pitch of the roof allows adequate head room for a livable space, whether access to the attic space can be provided in a practical manner, and whether the existing structure is strong enough for the contemplated additions. Unless a homeowner has extensive hands-on experience, it is a good idea to consult with an architect or engineer before proceeding with an attic conversion project. In addition to getting professional design help, the homeowner also needs to be sure the plans conform to local building codes.

Building a stairway for access to the new space is the first step in the project. This step may require some creativity if the available space is limited. Before framing new rooms can begin, existing plumbing, vent pipes, and electrical wiring need to be rerouted to be out of the way of, or incorporated into the designs for, the planned finished areas. Then the trussed roof rafters have to be modified to open up the interior attic space. This is accomplished by removing rafters and replacing them with vertical studs mounted on beams running lengthwise from gable to gable to support the trusses. A structural beam is mounted to support the roof’s apex and additional strength is provided by horizontal ceiling ties nailed across the trusses. The new vertical studs, ceiling ties, and exposed trusses provide the basic framing for the new interior space. The flooring is laid across the existing joists, or in some cases new joists have to be added first.

Next, new wiring and plumbing is installed to serve the new living areas, along with heating and air conditioning vents and windows. Windows can be installed in the vertical gables at each end of the attic or as open-able skylights in the roof. Adding dormers with windows can add more space and light. After the mechanical systems and windows are all in place, the next step is to add insulation around windows and between the roof members. Since the roof is the new space’s outside wall, it is important to provide insulation of an adequate R-value for the climate.

After the insulation is installed, the next step is to install drywall to define the walls of the living space. The space between the knee-wall and the roof is a good area to use for storage, so doors for access to this area should be included in the final finishing plans. After the drywall is up, it is time for the finish carpenters, plumbers and painters to come in. Light fixtures, bathroom plumbing fixtures, cabinets, doors, painting, and finish trim will complete the attic conversion and the house will have a beautiful new living space.

The cost of attic conversions will vary depending upon many factors, including scope of the project and quality of materials used. Whatever the cost, it is a very good investment that will enhance the value and livability of the home.
