A house in Cheam can be made more valuable if you opt for a loft conversion, that’s why many households in the town choose to have this kind of home upgrade. By converting a previously unusable area in your home into an extra bedroom, a new mini gym, or an efficient home office, you can increase your property’s value and make a profitable income in the future as you may decide to sell it. This is according to a recent study by the Nationwide Building Society. With a loft conversion, there will be an added percentage to your house’s current value which starts at 20% and can climb up to 25%.


There’s a long list to accomplish once you’ve decided to proceed with a loft conversion in your house in Cheam. No need to worry though as our team at Loft Conversion London will be with you every step of the way so we can complete this project swiftly. At the top of the list, is room inspection; we need to confirm that the area you want to convert has the standard roof height which is at least 2.2 meters. If your house is modernly built and features a trussed roof, then the measurement should be at least 2.4 meters to assure you of a comfortable loft. Once the head height is confirmed, then you can already picture your dream loft becoming a reality.


We will need to secure planning permission if the loft you want to build exceeds the limitations that are generally allowed under the right permitted developments. If your house is situated in a conservation area, then planning permission is needed. If the loft you want to build exceeds the current roof height your house has, then planning permission must be obtained. This process can be easily accomplished if you'll work with our expert team. We will make sure that if planning permission is necessary, we shall secure it before the loft conversion starts so we can avoid unnecessary inconveniences.


To avoid having your property get devalued after the conversion, a building regulation certificate must be secured. This will be provided by the local authority in your area or a private building inspection company. With this document in hand, we can assure the Building Control that the building plan for the loft conversion follows the standard safety procedures, including the appropriate fire safety measures like replacing all doors with fire-resisting ones, installation of sprinklers and smoke alarms, and more.


With the beauty of the benefits of loft conversion, you must be curious about the different types that you can choose from. Don't worry as we'll make the selection easy for you. If you want to go for the cheapest one, have the Roof Light loft conversion that allows you to enjoy a new, clearer view of the landscape available outside your house in Cheam. If you'd like to go with the most common type, then have the dormer type.

This is the best option for Cheam properties that have a pitched or sloped roof; with the conversion, the roof will undergo a structural change to give you the ample space you need. A hip-to-gable loft conversion is your best match if you currently reside in a semi-detached or terraced house and want to achieve lots of space in your new loft as it transforms the sloping hip in your property and extends it outwards and upwards to create a gable side wall. A mansard loft conversion fits almost all types of houses as this is the most expensive type. Unlike the other kinds, the construction work for a mansard loft is complicated which involves replacing your roof with a new structure that features steep sloping sides where a nearly flat roof will then be laid over it. Completion of this type is also lengthy which will likely take 10 weeks or more.
