A loft conversion is the process of transforming an empty ceiling space inside your home into a functional room, typically used as a bedroom, office space, a gym, or storage space. Loft conversions are one of the most popular forms of home improvement in San Diego as a result of their numerous benefits. The installation of a loft conversion is a complicated process. So then you need a specialist loft conversion company to undertake the task. HK Construction San Diego is one such specialist!

Loft Conversion Types

There are many types of loft conversions. These are two types most common:

Vaulted Ceiling

If you have high ceilings in your home then you can transform that wasted space into comfy living space. Often, up to 30% of a property’s potential space is located within the loft area. Therefore, converting this unused space provides a new area suitable for a wide variety of uses. Many homeowners choose to convert their open vaulted ceiling space into more space. This eliminates having to endure the costly and stressful process of moving to a larger home.

A mezzanine loft can be quirky and unusual, and they act as a gallery over the floor below. Rooms with high ceilings can feel vast and impersonal. So a mezzanine is an ideal solution for making a space appear more inviting while also creating valuable additional floor space.

Garage Loft

Building a room over your garage allows you to add more living space. Lots of options: Studio apartment, bedrooms, office space, game room, or a large storage room. By adding windows and balconies you can also increase your view and your property value at the same time.

A third one that is noteworthy to mention here is a commercial building conversion to residential living space. Most commonly warehouses, former factories, other commercial buildings, or even water towers. This type of loft first became popular in the SoHo section of New York City during the 1960s. Artists created living spaces on the upper levels of obsolete industrial building. While we can perform this commercial-to-residential service we prefer to work within residential homes.

Loft Conversion Features

There are dozens of loft conversion features with two main types being the most common:

Roof Window Conversion

Roof windows are often an attractive option for homeowners. Because they can fit neatly into the roof-line they do not require any major restructuring of the roof itself. Obviously such windows will provide the loft space with lots of natural light.

Dormer Conversion

The term “dormer” is commonly referred to a “dormer window” although a dormer does not necessarily contain a window. A dormer window is an extension of the roof that has a window in it. A dormer is great for providing more space and headroom within the loft. Dormers are also popular due to how great they look. Many people find them appealing.


The first stage of any loft conversion is to have a close look into the loft space to determine whether conversion is feasible. We have to make sure there is enough available space under the ridge of the roof. A measurement of 8’ allows enough headroom. Although you may find that as little as 7’ will work too. Due to the slope of the roof and the headroom requirement, the feasibility of a loft conversion depends upon a minimum functional height. Providing that this requirement is met, most properties will likely be good candidates for a loft space conversion.

Additionally, we will check the roof to make sure it is weather proof and sturdy. If not, then we need to make such repairs so that the new loft is weatherproof as well. Roof repairs usually take place during the loft conversion construction process.

Structural strengthening of the ceiling, walls, and floor may be involved too. Because ceiling joists in most homes are designed to support the weight of the ceiling. Therefore, when adding a loft, additional support is required to transfer the loads from the new loft floor to the walls of the house. We handle all of this for you as part of the loft conversion process.

Building Permits and Code Regulations

San Diego requires building permits for loft construction. Also there are code requirements to meet. HK Construction will meet all the legal aspects of your loft conversion from start to finish.
