Why opt for a Loft Conversion

A loft conversion is an ideal way to make use of extra space in your house. You’ll be surprised by the things you can transform an area into like a chamber with one or two bedrooms, a bathroom, or if spacious enough you can turn it into your very own home office. Converting a loft would also lead to energy efficiency—aside from the fact that it adds value to your property by 20%—since installing large windows would mean you can enjoy natural light, and an insulated roof will keep the warmth of the room even during the winter season. Redesign your empty den by giving it the life it needed, which is more a cost-effective option than changing addresses.

Loft Conversion Types

What type of loft conversion is most suitable for you will depend on three important factors: your roof, your loft conversion purpose, and your budget. Examine your roof and take note of your ceiling height, it helps to remember that the minimum required measurement should be 2.2 meters from the floor to the highest point in your loft. Also, kindly keep in mind that though you’re going for the affordable alternative, chances are you are still required to spend a huge amount of money not only for the materials to be used in the construction but also for several professional fees that include building regulations, building control, and party wall arrangement.

Now, if you’ve considered the factors, you can now start finding the most appropriate loft conversion type for your Isleworth house. Internal loft conversions will be the cheapest and easiest type because there isn't much construction required, you’ll just have the option to choose an appealing Velux window and the room will be all set.

Dormer loft conversions that vary from single dormer, hip-to-gable, and L-shaped dormer will grant you more floor space and additional headroom. This kind of loft conversion may require you to secure planning permission from your local council since this type will mainly change the structure of your roof to achieve the appropriate symmetry. A mansard conversion will give you all the freedom to do what you want but also will make you spend more compared to the first two types as the process involves replacing your roof with a new structure that features steep sloping sides where a nearly flat roof will then be laid over it. As for this type, you’re guaranteed to enjoy enough space to create a kids' room, a multipurpose room, or even a home library. You just need to take note that before proceeding with the construction, you need to secure planning permission firsthand.

Loft Conversion Process

Once you've decided that your dream loft conversion is going to be a reality, the next step is acquiring essential documents such as planning permission, a building certificate, and for some a party wall agreement.

Planning permission

A loft conversion is generally allowed under the right permitted developments but because there are several loft conversion types that require a structural change or roof extension, you may need to obtain planning permission before proceeding with the construction.

Building Regulation Certificate

To ensure that the project will undergo safety measures and will follow a set protocol, having a building regulation approved by the local authority is a must.

Party Wall Agreement

For homeowners of a semi-detached or terraced house, securing a party wall agreement that will notify your neighbors about your desire to have construction on your property must be settled first. As you complete all the necessary arrangements, our team can now start working on your loft conversion. At Loft Conversions Company, we're committed to providing you with the best possible service when undertaking your loft conversion.

As we begin with the project, there may be construction aspects that may sound new to you so allow us to give you a quick and simple run-through of how we do our work:

The first step is removing the old plaster ceiling and timber flooring.

The second step is installing new floors, wallboard panels, and double-glazed windows.

The third step is installing skylights which will provide the room with natural light, adding Velux windows, and finishing the tiling process in the outside walls or outside roofline if applicable.

The fourth step is when we’ll add the interior partitions or ceilings as well as a brand-new staircase.

Lastly, we’ll finish off the construction by covering all walls and ceilings with plastered boards followed by either exterior color coating or white painted surfaces depending on your preference.

If you want to install a bathroom in your loft, we can fit it just above your existing bathroom so there won’t be necessary changes with the pipework and we can easily connect the drainage and water supply for a more convenient process.


If you're planning on selling your Isleworth home, you might be considering a loft conversion. Loft conversions are popular because they can increase the amount of space in your home, and make it more attractive to buyers. Loft conversions in Isleworth are energy efficient. Loft conversion work involves removing the existing ceiling and installing a new ceiling that can be insulated, increasing the thermal efficiency of the property. This means that loft conversions can reduce your heating bills and make your home warmer in winter. It’s also worth noting that loft conversions can help to improve the insulation levels in your home if you have an existing roof space with little or no insulation.


Loft conversions are a great way to add value to your Isleworth home.

Improved heat efficiency: Adding insulation will help make sure that heat stays in during colder months and doesn't escape during warmer ones. This will also save money on heating costs!


Yes, there are a few special considerations that you should take into account before undertaking any loft conversion work in Isleworth. Firstly, check for access restrictions and the size of your attic space. Also, it's essential to consider whether or not you have enough headroom to install new stairs and if this will impact an existing bathroom or bedroom below. Lastly, you'll need to find any potential damp problems in the area that may need rectifying before the work can begin. If you consider all these things, it will help to make sure your loft conversion project is successful!


Yes, you can install solar panels on your loft roof as part of the conversion project. Ensure that the angle of your roof is suitable for installing solar panels, and check with a qualified engineer before doing so. Additionally, you'll need to consider where the wiring needs to go and if any additional structural changes may be required. Considering all this will ensure that your solar panel installation goes smoothly, making your loft conversion even more worthwhile!


It is possible to convert a loft into a separate living space. You'll need to ensure that the new space complies with all building regulations and check for any access restrictions before beginning work. Additionally, it will be necessary to consider ventilation and drainage needs and install water tanks and pipework to provide adequate plumbing services.

A Loft Conversion is the quickest way of increasing the amount of living space in your Isleworth home. Did you know recent research undertaken by Nationwide Building Society has shown that a Loft Conversion can add over 20% to the value of your property? Moreover, it can improve your home’s energy efficiency too. All that extra insulation will surely bring down the cost of your energy bills. By converting your loft, it makes use of “unused” space to create an extra bedroom or bathroom, rather than eating into your garden. Overall, it costs less per square metre to convert a loft rather than build a rear or side extension, as most of the structure needed is already in place. Most of the loft conversions can be carried out without the need for planning permission if they don’t exceed a certain size. (40 cubic metres for a terraced property and 50 cubic metres for a detached house).


Our process includes an initial survey and design followed by architectural drawings and structural calculations. Here are the eight stages in our Loft Conversion Building Process:

  • Stage 1: Scaffolding is erected to get access to the loft
  • Stage 2: Structural beams are installed into party walls to create timber floor support and front roof elevation with dwarf wall.
  • Stage 3: Build the dormer structure and install Velux windows.
  • Stage 4: Finish roof tiling to both new dormer and front roof elevation
  • Stage 5: Build interior partitions, doorways, and ceilings.
  • Stage 6: Install double glazed windows together with floor and wall insulation.
  • Stage 7: Install new staircase between first floor and loft.
  • Stage 8: Plasterboard all the loft and complete with plaster skim.
  • Our team is ready to always discuss any aspect of the project in more detail.
