This may not necessarily be accurate so it is best that we provide you with a written personalised and tailored quotation, which will be sent out to you. This quotation will clarify the various options which are available to you and the different, competitive costs to make your chosen options happen and become a reality.

Can My Loft Be Converted?

The short answer to this question is YES. All lofts can be converted; the question is can it be done within the existing roof space or will more space need to be created, altering your existing roof or living space. Once you have contacted us, one of our Create Room team can further advise you on a loft conversion.

Do You Need Planning Permission For A Loft Conversion?

This entirely depends on the type of loft conversion that you want. If your loft conversion idea does not extend outside of the existing structure of the property, you may not need to obtain planning permission.

However, it is always best to contact your local council for information on loft conversion building regulations and planning permission to help you understand where you stand. If you find that you do need planning permission, you should try to find out as soon as possible so you can factor the cost of applying for planning permission into the overall loft conversion cost.

  • Conversion Types



    Velux has over 60 years of experience as the leading manufacturer of roof windows in the UK. The name Velux has become synonymous with loft conversions, this is due to the fact it is one of the most cost effective loft conversion options and does not always require planning permission. Velux windows are commonly used for loft conversions Essex wide and throughout the UK.

    Fitting flush with the roofline, Velux windows are designed to leave the existing roof structure untouched. This requires less construction work than a dormer loft conversion and most other types of loft conversions, which also helps to keep costs down. Whilst you may not need planning permission, it is always wise to check online or with your local council before embarking on your loft conversion ideas.

    A Velux loft conversion is ideal for a property with a large amount of headroom in the loft, or if you are restricted by the planning constraints that come with living in certain areas, e.g. conservation areas. If headroom is limited then opting for a dormer loft conversion or a Mansard loft conversion may be the way to go. Velux windows, and most other roof light windows, are very simple and quick to install.

    Velux windows let in a surprising amount of light due to the fact that they are installed at an angle, typically level with the roofline rather than vertically or horizontally. Depending on which cardinal direction you choose for your Velux window installation, the amount of light and even the room temperature will differ depending on the location of your property, the surroundings and the time of day. For optimal use, you may wish to consider installing tailor made thermal blinds that help to contain heat, this could result in your loft conversion saving you money on energy and ultimately reducing the loft conversion cost over time.

    If you are considering a loft conversion in Essex, London or the Home Counties, Create Room can help you bring your loft conversion ideas to reality. Contact us to discuss your loft conversion plans and obtain a quote from our specialists!


    conv_dormerA dormer loft extension protrudes from the existing roof structure, expanding the headroom and floor space of the loft conversion. Dormers extend beyond the rafters and are typically featured at the front or rear of the property, coming in a variety of different dormer loft types. The walls of a dormer are typically vertical, with the ceiling being horizontal, in contrast to the slanted ceilings of standard loft conversions. This adds a large amount of internal space for properties with limited headroom, making a loft conversion more feasible for home expansions.

    Flat roof dormers may not be as attractive but they are an excellent way to capitalise on unused space while also being a cheap loft conversion option in comparison to gable-fronted or hip roof dormers. Hipped roof or gable front dormers are considered much more attractive but the construction is much more complex, resulting in a higher loft conversion price.

    There are different types of dormer:

    • Gable fronted dormer – these are sometimes called a dog house dormer
    • Hipped roof dormer – a dormer with a hipped roof
    • Flat roof dormer – you guessed it – it has a flat roof!
    • Shed dormer – a single planed roof that is pitched at a shallow angle to the main roof

    This option is most suitable for small loft conversions where there is limited space. It creates additional headroom for the new room(s) and affords additional space for the loft conversion stairs. The increased height created by the Dormer allows for simpler installation of bathroom fittings, if including an extra bathroom is your intention.


    conv_mansardNamed after Francois Mansart, a French architect from the 17th century, a mansard roof is commonplace in the UK and a popular option for loft conversions London wide, in Essex, and throughout the home counties. It has two slopes positioned at different angles, with one slope at a steeper incline than the other and an almost flat surface at its peak adjoining the 2.

    A mansard loft conversion maximises the available space within your loft, commonly built by raising the party/gable walls either side of the property to form the profile for the mansard prior to the creation of the timber frame. Mostly found on older properties, a large portion of loft conversions in London are mansard loft conversions.

    The ‘average’ 3 bed semi-detached, terrace or bungalow loft conversion is more suited to flat roof dormers thanks due to the reduced cost and simpler construction. A mansard is not a cheap loft conversion option and will almost certainly require planning permission.

    This type of loft conversion is also designed within the countryside areas of the North West, where clients are following the Mansard Loft trend of similar conversions within their locality. This type of conversion was the preferred design a number of years ago and is most likely to be the preferred option from a planning perspective in sensitive areas.

    Hip-to-Gable Loft Conversion

    Hip to Gable Loft ConversionThe hip to gable loft conversion is typically chosen by owners of detached and semi-detached properties. By extending the sloping sides of the roof outwards, the existing sloped roof is replaced with a vertical wall (gable) that reaches the same height as the peak of the roof. Double Hip-to-Gable loft conversions can be built in houses that have two sloping sides, rather than one.

    While Hip-to-Gable loft conversions with modular designs are constructed using steel frames, they are standardly built using timber. To match the tone of your existing brickwork, brick slip cladding can be installed with relative ease in order to maximise aesthetics. Whilst they tend to fall under permitted development which does not require planning permission, there is a possibility that you will, so it is always best to check with your local authorities when exploring any loft conversion design ideas and before starting construction.

  • Why Convert Your Loft?

    Things change. It’s a fact that our needs and expectations don’t stay the same. There may be a reason or a desire to create more living space.

    The current economic situation has made moving properties increasingly difficult and expensive. You don’t have to leave the place you call home to gain the additional space you want. The unnecessary disruption of relocating, Estate agents fees, legal costs, stamp duty and removal expenses can be avoided.

    Your existing loft space could become the additional bedroom you need, a playroom for the children, a working space at home or an additional shower room for your teenagers or guest. The list is endless.

    “In addition, the men in overalls attack the conversion from the outside, via scaffolding, so you can continue to live at home during the process. Try that during the grind of a basement extension. Provided it is quick and relatively hassle-free, a loft conversion is a good investment, too. Spending up to £50,000 on a standard job is, according to Cuthill, “a bargain”, considering the extra space you get and London property prices. It could add up to 20 per cent to the value of your home.

    “It has been proven that by converting your existing loft area in to a habitable room adds value to your home. Loft Conversions are ‘biggest boost to house values’.

    “Homeowners looking to add significant value to their properties should consider carrying out a loft conversion. A new study by Halifax Bank found that loft conversions are the biggest value-boosting projects, with experts saying they can increase a property value by an average of £20,876, at a cost of about £10,000.

    “In times of rising property prices, more and more people are turning to loft conversions to solve the problem of extra living space. Loft conversions are a significant investment and can cost from £20,000 but research shows that in the majority of cases they do add more value to the property than the initial outlay.

    “It’s estimated a loft conversion can add an extra 10% to a property’s value.

  • Design & Planning

    The team at Create-Room can originate full working drawings and structural calculations for your proposed loft conversion.

    We will demonstrate our experience when preparing your plans. They will be originated to provide you the maximum space achievable while being considerate to the existing property. We will consider all relevant approvals required so that they are considered in the design of your loft.

    Loft design is specialised and many draughtsman do not consider ambiguous elements such as creating adequate head height, the positioning of staircases and structural steel formation when designing the loft layout. We have the experience so that we do consider these factors.

    We have numerous lofts that we have previously converted for you to look at. This may help when deciding on a final design for your loft conversion.


    An appointment will be made and one of our experienced Surveyors will visit your property. Accurate measurements & dimensions of the existing dwelling are recorded and photographic evidence of your existing property will be taken.

    This will enable us to be sympathetic with the existing property when designing your proposed conversion. Preliminary drawings will then be originated in accordance with your specific requirements.


    The preliminary drawings will be presented to you for your approval. Any amendments in the design or layout can be made at this point.

    Once you are happy with the plans, Full working plans will be originated incorporating a structural layout. Full, working structural calculations will be originated.

  • Building Regulations

    Building Regulation Approval

    All loft conversions need Building Regulation Approval. Either you’re Local Authority or an Independent Building Control Company would be appointed.

    Full plans and structural calculations will be submitted to the chosen Building Control authority. These, in turn with onsite, visual inspections will ensure that the proposed design and work is sufficient to meet their requirements.

    Once they are satisfied that your loft conversion meets the set Building Control Regulations, a completion letter will be forwarded to you.

    Permitted Development Allowance

    A loft conversion for your house is considered to be permitted development, not requiring an application for planning permission. This is because the effect of such developments on neighbours or the surrounding environment is likely to be small.

    The permitted development allowances described here apply to houses and bungalows, not flats, maisonettes or other buildings.

    If you are unsure, your Local Authority will be able to confirm if your permitted development rights have been removed from your property

    The following conditions and limits must be met to ensure your proposed loft conversion complies with Permitted Development:


    Any additional roof space must not exceed these volume allowances:

    – Terraced Houses & Bungalows 40 cubic meters
    – Detatched Houses & Bungalows 50 Cubic meters
    – Semi-detached Houses & Bungalows50 Cubic meters

    Please bear in mind that any previous roof space additions must be included within this volume allowance. Although you may have not created the additional space, a previous owner may have done so.


    Roof extensions are not permitted if your property is within a conservation area.


    An extension beyond the plain of the existing roof slope of the principal elevation that fronts a highway is not permitted development.


    Materials to be similar in appearance to the existing house.


    No part of the extension to be higher than the highest part of the existing roof.


    Balconies, verandas or raised platforms are not permitted development.


    Any side facing window must be obscured glazed and non-opening unless the parts which can be opened are more than 1.7 meters above the floor of the room in which it is installed.


    Roof extensions, apart from hip to gable ones, to be set back, as far as is practicable, at least 20cm from the eaves.

    The 20cm distance is measured along the roof plane.


    Work on a loft or any roof may affect bats. You need to consider protective species when planning work of this type.

    Certificate of Lawful Use

    If you want to be certain that your property does not require planning permission, an application for a lawful development certificate can be applied for at your local authority.

    It is not compulsory to apply for a Lawful Development Certificate but you may be required to produce one at a later stage for example when selling your property.

    This certificate will confirm that your loft has been converted using your Permitted Development Allowance.
    Planning Permission

    Should your proposed loft conversion not be permitted under Permitted Development and a Certificate of Lawful Use be refused, a Planning Permission Application would need to be submitted to your Local Authority. It is their responsibility to decide whether a proposed development should go ahead. Planning permission takes approx. 8 weeks from the date the validate your application. We will consult with the Planning Officer appointed to your application to check the progress of it and act accordingly should it be visible.
    Party Wall Agreement

    Walls shared by adjacent properties are usually jointly owned by the two owners and are termed party walls.

    The party wall act provides a framework for preventing and resolving disputes in relation to party walls.
    If you intend to carry out any work to the party wall, it is your duty to inform your neighbouring property of your intentions. This should be done in writing before work commences.

    The Act contains no enforcement procedures for failure to serve a notice, However, if you start work without having first given notice in the proper way, adjoining owners may seek to stop your work through a court injunction.

    An adjoining Owner cannot stop someone from exercising the rights given to them by the Act, but may be able to influence haw and at what times work is to be done.

    It would be advisable to discuss your plans with your neighbour first. You may find that they have no objections. Even if they are not 100% supportive of your decision, they will no doubt appreciate being asked and consulted.

    We can recommend a Party Wall Surveyor should it be required.
