As you plan your attic remodel, you will want to get a good estimate of the costs involved.  Basically, these costs fall into three categories:  planning and layout, materials, and labor.  Within each of these categories are several kinds of costs.

1. Planning and Layout – The planning phase of your remodel will require expenditures associated with the design and with permits.  In a nutshell, here are the costs during this period of the project:

  • Building Plans – professional fees for an architect or a draftsman
  • Design Preparation for the attic – fees for either an architect or an interior designer
  • Engineering inspection – costs for an evaluation of the present walls’ sturdiness in terms of bearing the added weight of construction.
  • Decorating Advice – decorator’s pay
  • Permits and Assessment fees

2. Materials – A second source of costs involves the materials required for your remodel.  To determine what these costs will be, make a list of materials you are going to need during the whole construction period.  Don’t forget to plan for extras in the attic space, such as a bathroom, skylights, and built-in storage. The main materials are:

  • Wiring
  • Paneling or Drywall
  • Plumbing
  • Windows
  • Lumber to be used in subflooring and scaffolding
  • Ceiling materials
  • Vents
  • Flooring materials
  • Lighting fixtures
  • Additional cooling and heating equipment, if needed
  • Hardware
  • Insulation

3. Labor/Workers – The last major group of costs involves the labor during the construction period. You may need to hire professionals or licensed workers, like an electrician or a plumber, to satisfy building permits. If you plan on employing the services of a general constructor, you may get a single cost estimate for all these components of labor. Nonetheless, you will also incur other labor costs on sub-contractors and materials delivered to your home, etc.

The following are the labor costs that are usually included:

  • Carpentry – construction of the sub-floor, framework, ceiling, and access stairway
  • Plumbing draftsmen and finishers
  • Electrical draftsmen and finishers
  • Building of floor, walls, and ceiling
  • Installation fees for ventilation and insulation
  • Carpentry –construction of a storage space, if required.
  • Carpentry – for the structural reinforcement of outer walls, if required
  • Labor for painting and polishing jobs
  • Labor for the trimming and finishing

When you have all of these costs in hand, you will be able to make a good estimate on how much you will be spending both before and during the construction process. A trustworthy estimate from a general contractor, good quotes on material prices, and a guarantee that you will stick to your plan during the construction period will provide you with a dependable cost estimate. Common practice is to add at least 20% to your total best estimate, and that will give you a working financial plan that should adequately cover the costs of your attic remodel.
