Converting an unused part of the house to a living accommodation is not a new concept. Over the past decades, the unused roof void (that is between the main house ceiling and the roof) has become one of the more popular "extensions" to home living space without much consideration (or at least minimal concern) to floor area. In general terms, loft conversion is the development of an empty attic space to a functional living area. This is typically used as either living quarters (that is, an additional bedroom, library, office or family room) or as storage space. Because of their apparent numerous benefits, loft conversions are particularly accepted in predominantly vertical residential areas. This is quite evident in places like England and Japan. Because it is a complicated process, many people actually consider hiring someone to build it for them. Notwithstanding, loft conversion is considered as a DIY or "do it yourself" endeavour.

As mentioned, loft conversions have numerous benefits for homeowners. This is actually the primary reason for its increasing popularity. Converting the attic (or for that matter, the void between the ceiling and the roof) provides a significant amount of room that can be used for several purposes as mentioned above. Also, having a loft in your property creates significant value. And this of course, translates to more money should you decide to sell your place. Apparently, it increases the property value to approximately 20% just because of the loft.

In the early years, the basic roof structure of most houses could not sustain the required integrity of putting an additional living quarters. By the fifteenth century however, the attic had begun to appear. Access to these attic spaces was initially through a simple ladder or at times, if there was still enough space, a modified staircase was created. These small attics eventually have become the predecessor of what we now call "a loft". In modern times, several home builders have already incorporated the development of lofts as early as the initial construction of the main house. These lofts have ultimately become synonymous to "private" living quarters typically popular in large families.

In building a loft, before any firm plans or budget costs can be prepared, a survey of the existing roof void must be initially done. The survey must be accurate. Planning based on approximations, even at this early stage, may result in inaccuracies in the construction later. After surveying the roof void, you should also survey the structure that will support the entire loft itself. Surveying should be up to ground level to accurately determine structural integrity of the planned loft. It is most important to determine which of the internal walls are weight-bearing. This means you should know the basic foundations that will establish clearly the existing supporting structure of the loft.

Basic planning for a loft conversion involves critical factors regarding the potential viability of the project.

• Adequate headroom.

• Full height floor space.

• Lighting.

• Access.

• Ventilation.

In summary, the popularity of loft conversions is progressively growing because of the apparent benefits it gives the homeowners, in terms of both space and property value. Furthermore, it provides the much needed privacy for those who require an area where they can relax, work or spend quality time with their house mates.
