What is the Most Expensive Part of a Loft Conversion?

Before you decide to proceed with a loft conversion, you need to have the plans approved by building regulations. This approval is crucial if you want to sell your house in the future. If it is not given, your work may be illegal and unsafe. You can work with a building firm or a specialist loft conversion company to achieve this.


The cost of an architect varies depending on the complexity of the conversion. A simple conversion does not require a great deal of structural calculations, while a two-storey extension will. Our architect will also help with any planning permission applications, if needed.

If you want to convert a loft without planning permission, you must have full plans approved by your local authority. This will reduce any risks of the work not complying with the regulations, and it will also help you get a fixed quote from a builder. A Building Control officer will check the progress of the work throughout the process, and will issue a completion certificate.

Dormer conversions

One of the most common types of loft conversions is the dormer. These add extra light and space to a space. As well as providing extra space, dormers also improve the value of a property. However, you need to factor in cost when planning a loft conversion.

Dormer conversions can add up to 50 square metres of space to your home. These are ideal for families looking to add extra bedrooms or new additions. This type of extension is particularly efficient for properties with steep pitch angles because they maximize the amount of usable floor space. Normally, dormer conversions are installed by opening up the roof and cutting the timbers on site. However, some loft conversion companies manufacture the dormers off-site and then lift them into place.

Planning permission

Planning permission is the most expensive part of completing a loft conversion in Warlingham. It's essential to get permission in order to get the work done legally. This process differs from house to house, and the status of the property will influence whether or not the conversion can be carried out. For example, a conversion of a listed building will require notification to the local planning department. In addition, if the loft conversion is higher than the original roof, it can affect nearby properties. In this case, neighbours can object to the conversion within 21 days.


Adding a bathroom to a loft conversion is a very expensive project. The cost depends on the size of the bathroom and its fittings. It also depends on where you want to place it in the loft conversion. It can save time and money if you position it above an existing bathroom, as this will require less re-routing of plumbing.

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.
