Loft Conversion in Surrey 

There is no doubt that it's easier to extend than to move. If you've got some unused space, it's worthwhile thinking about building into it to create that in-demand extra space. If this is what you are looking for then Loft Conversions, London is your go-to solution.

This should be your cue to get the most from your property — going up, going down, going in and going out. A loft conversion is an ideal way to gain more space. There may be scope for one or two extra bedrooms possibly even with a bathroom or home office that you haven’t even thought of.

A Loft Conversion might be a minimal transformation of the attic into a functional space such as an extra bedroom, a gym, an office, a bath; basically, into anything that one would want to have. Due to the added aesthetic and spatial value to the property, loft conversions are one of the most favoured and popular forms of home improvements in the United Kingdom.

Loft conversion transforms the unoccupied, comparatively lesser-used spaces of your residence into a beautiful, habitable one, making the living space more spacious and preventing the need of having an alternative solution to entirely change your place. If you have to go by facts, there is given proof that Loft Conversions increase the house selling price by 40%, statistically speaking. And that’s what we provide you with, at Loft Conversion Surrey

A brief history about Surrey

Surrey is an administrative and historic county of southeastern England. This magnificent county is situated in the southwest of London, adjoining the River Thames. The history accounts for the location of this beautiful county’s administrative centre in the London borough of Kingston upon Thames. In addition, a small part of Surrey, including Gatwick Airport and its immediate environs, lies within the borough of Crawley in the administrative county of West Sussex.

The services by Loft Conversions Surrey provide you with the perfect place for your space. Choose your loft to be converted in different styles, keeping in mind the necessities that you have and even your budget. There are different kinds of Loft conversions depending on what you have in mind and your residential space.

There are three types of loft conversions that we offer- Internal loft conversions, Dormer loft conversions and the loft conversions that require a Full Removal and Build.

Internal loft conversions are usually the cheapest and require minimum building intervention. However, dormer loft conversions are the most common type of loft conversions in the county because of the additional space they can provide, with relatively simple building works. Full removal and build loft conversions will give you the most flexibility, but they are the most complex and most expensive.


Roof Lights - These are the most cost-effective loft conversion as they involve converting the existing loft space. Very little alterations to the roof space are needed.


Single Dormer - These are favoured by planners in conservation areas. If permitted, two of these can be used to increase space and add symmetry.

Side-Dormer - A side-dormer is often used to increase head height for houses with a hipped roof, where access to the loft is located under that hip.

Hip-to-Gable - Involves one or more of the hips being replaced with a gable wall (where the roof slopes in from the sides as well as the front and back). The roof is then extended over these gables to add extra space with full headroom.

Full-Width Dormer - This type of loft conversion will really maximise space and achieve a completely different feel to any other type of loft space.

L-Shape Dormer - These are only suitable on certain properties such as Victorian properties with an addition to the rear. The L-Shape Dormer provides a significant amount of additional space.


Mansard conversions - This type of loft conversion involves one or both slopes of the roof being replaced with a new structure with very steep sloping sides (almost as steep as the walls). An almost flat roof is placed over the top. This design is used where the original roof had little or no headroom and creates sufficient volume for an additional storey. Mansard conversions normally require planning permission.

Pre-fabricated loft - Where vertical space inside a roof is limited, the existing roof structure can be replaced with a larger one. “Room in the roof” trusses can be craned in place to form the shell. The roof can then be constructed around them. But living without a roof for over a month is no fun! But a pre-fabricated unit can be watertight in a couple of days.


The most popular type of loft conversion, that we suggest, is the L-Shape conversion with owners of Victorian terraced houses and properties of a similar style. It involves constructing two dormers – one over the roof of the main house and a second above the rear extension. In the majority of cases, the second dormer will be constructed above what is usually the existing kitchen or bathroom. The two dormers meet to form a right angled ‘L’ shape (how this type of conversion came to be named).

The advantage of an L-Shape conversion is that it allows you to almost replicate your first floor in terms of space and design. It gives you the possibility for even three or four new rooms and no other type of loft conversion will give you as much additional space.


The question of how and why usually arise as to how to get your loft conversion done or why to get your loft conversion done. While we have already told you about how the loft conversion could help you in increasing your house’s price and getting more in return for your property, there are few other reasons that we can help you with.

  • Building upwards instead of outwards  -

Planning to renovate your house and adding extensions would require a lot of work and not to forget, an extension would require the permission of the council. Loft conversion makes the most out of the waste space with the utilisation of it in the most effective as well as required space possible.

  • Additional Bath   -

You can never run out of baths. Having an additional bath is a bane rather than a boon, knowing that you will not have to wait in queue for your turn to show up, in the most difficult manners possible.

  • More Storage   -

You can always run out of storage because things will keep adding up and your space will be filled. Having an organised space for your stuff and future additions would be a benefit that you didn’t know you needed.

  • Take care of the warmth  -

Most of the heat or insulation in your house is lost due to the loft. Having an extra space or room in place of the loft will only let your house remain more insulated.

Opting for Loft conversions is a wise decision and a brilliant way of improving your home. There are a lot of factors that affect the loft conversion that you’d need to take care of, like the house condition, the design type, the materials required, the permissions, budget etc.

  • House Condition   -

Three important things are generally inspected when converting a loft. The Internal Height, Roof pitch and the Footprint -

  •  The Internal height is nothing but the headspace, which is crucial for the livability factor.
  •  The roof pitch is the proper angle that will provide roof conversion.
  •  The footprint is the basic measurement that is necessarily adhering to the internal rules.
  • Permissions  -

 If you want to have a different renovation that might exceed specified limits as provided by the council, then you will need to ask for planning permission. You'll have to submit a full planning application. Some properties don't have developmental rights so you should be sure to follow up with the council. On the contrary, you don't generally need the permissions from the council to get your loft converted, but you can always check it to be a hundred per cent sure. 

  • Design   -

The design of your home and your loft will be the prime role player, as to what your loft would be converted in. Considering the types of Loft conversions that are mentioned, your loft will be given the appropriate transformation.

  • Budget   -

Now your budget will tell a lot about the kind of loft conversion that would take place in your house. Considering the amount of money that can be invested vs the amount of work that would be invested are two of the prime players that will determine your loft.

A successful loft conversion is a definite asset to your home. It can provide useful extra space and add value to your property. However, a poorly converted loft can reduce your property’s value and in some cases compromise your safety and the structural integrity of your home. So, make sure that you seek proper assistance when it comes to a loft conversion.

With Loft Conversion Surrey, you can never go wrong. As you can see there are many elements that you ought to consider when planning a loft conversion. If you want to make sure it's done right, we most definitely are your best guides and we make sure to ensure that you have a quality loft conversion that stands the test of time and adds value to your property.


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.
