How Stressful is a Loft Conversion in Caterham?

When planning a loft conversion in Caterham, it's best to hire a professional to take care of the project. We have a dedicated site manager who can help you plan the project, and keep in regular contact with you. Before hiring a loft conversion company, make sure to have your own set of specific requirements in mind. For example, if you're planning to build an en-suite bedroom in the loft, you'll need plumbing. In addition, you may want to add more skylights.

Hip-to-gable loft conversion

A hip-to-gable loft conversion is a complex job, which involves several different contractors. Two to three people typically work on the project at any given time. The size of the conversion will also affect the overall cost, as a larger loft will require more materials and labor.

Hip-to-gable loft conversions are the best option for homes that have hipped roofs. These are usually on the ends of terraced or semi-detached houses. The conversion of this type of roof will provide you with more head height, allowing you to use the loft internal floor space more effectively. In addition, you can use the extra space for a variety of different purposes, including a home office or leisure area.


When planning a loft conversion, it's essential to follow building regulations. Using a detailed plan ensures your new space is safe and structurally sound. It also ensures that both you and your contractor are on the same page. If you're unsure about the process, consider consulting a professional builder or architect who has experience in loft conversions.

RSJs, or rolled steel joints, are used to reinforce internal walls and provide strength in loft conversions. They can be made of structural steel or a combination of steel and aluminium. They're usually I or H-shaped and are an excellent choice for loft conversions. The steel is designed to resist bending and will not crack when placed under load.


When undertaking a loft conversion, it is important to keep your family's needs in mind. You don't want to disturb their lives by having a noisy loft conversion or causing a large amount of disruption. It is also important to keep a tidy home all the time. You should also be aware of the risks associated with building work, including noise and dust. Fortunately, scaffolding can help minimize any disruptions.

Victorian and Edwardian Houses

The most common loft conversions are done on these types of houses across London. These houses mostly have high ceilings and large rooms and a conversion works best when the design retains the natural character of the building.

End of Terraced and Semi Detached Houses

If you live in an end of terraced or semi-detached house, your property is ideal for a loft conversion. There are two main types of loft conversion that are suitable for semi-detached and end of terrace homes: hip to gable loft conversions and dormer loft conversions.

1920s and 1930s Houses

Many properties in the UK were build in the 1920s or 1930s (pre-war period). Such houses are great for loft conversions, you can easily add either a dormer loft conversion, a hip to gable loft conversion or a Velux loft conversion. The type we build will depend on the structure of your home and roof we can guide you on the best approach.

Flats, Maisonettes and Conservation Areas

If you happen to live in a conservation area, the local council may not permit you to have a rear dormer, but they might let you have a mansard or a combination of Velux roof windows and small dormers. Loft conversions in flats and Maisonettes are the ultimate way of gaining that precious extra space.
