The first step is to define a general list of objectives by identifying from a functional perspective what you would like to achieve. For example, do you require a family(tv) room, an office/computer area, a bathroom, laundry/utility room, etc.. If you intend to remain in your current house for many years to come, try to anticipate as to whether the function of each room may change in the future. For example, when our daughter or son go to university they can use the basement as a small apartment or we will be getting a home theater system in a couple of years. Some thought towards the future will ensure that these needs are worked into the original construction, thereby eliminating the mess and cost involved in renovating again.

Establish a List of Priorities
As with most projects of this magnitude there will undoubtedly be some compromises due to potential space limitations and/or budget constraints. Determine what is most important, for example the family/tv room or a finished laundry/utility room.
Rough-out Your Floor Plan
Measure and layout a general floor plan of your existing basement. Don’t forget to identify the approximate position of columns, beams, the furnace, laundry tubs, etc.. Based on your list of priorities start laying out each room, working from most important to the least important. To assist with minimum room dimensions use a similar main floor room as a guide. For example, use your main floor family dimensions (remember to increase its size by 20%) for your basement family/tv room.
Do not worry if a room does not fit exactly within a given space. At this point you are only trying to determine if there are any major room size constraints or positioning problems. Consider a room size to be constrained if you have to reduce its dimensions by more than 10% in either width or length. Position problems exist where a room overlaps a fixed item such as the furnace. If you encounter either constraint, then you might have to reduce the number of rooms (remember your priority list) or try to create multi-use rooms instead of separate rooms. For example, one leg of an “L” shaped room could serve as a tv/family area, while the other leg serves as a computer/office area. Maybe the bathroom could be integrated with the laundry room by incorporating the washer and dryer into a closet with sliding doors.
Develop a Budget
With your rough working plan at hand, calculate the total square footage of finished floor area (room length x room width = square footage). To calculate your budget range, multiply the total square floor footage by $25.00 and by $35.00. This will provide you with an approximate low/high range for all your basic construction building materials and installation labour. Now add in any costs for extras such a bathroom fixtures (toilet, shower, taps, etc.), finish flooring (carpet, hardwood, ceramic), gas fireplace, etc.. You now have a reasonable projection as to the likely cost to complete your project.
