Dormer Loft Conversion in Brighton, East Sussex

Are you in need of extra space and considering moving? Before you start going to open houses and calling your realtors, wait a minute. Have you considered converting your loft into extra usable space?

One of the easiest ways to obtain a functional office space or an extra guest room is to have your loft converted. When it comes to loft conversion in Brighton, the most popular style still remains dormer loft conversion. A dormer loft conversion is a structural extension projecting vertically from the plane of a sloping roof.

In other words, it is basically an extension to the existing roof. Building a dormer onto an existing roof is a sure-fire way of transforming it into a functional space.

How do you then build this dormer? By yourself? Certainly not. The installation of a loft conversion is a complicated process and though it may be possible to attempt to do it yourself, the large amount of work involved makes contracting a specialist the easier and safer option. To get the best out of your loft in your Brighton home, engage the services of a professional loft conversion company, Clifton Hill & Mont Pelier Conversion.

Our dormer loft conversion designs will not only create a magnificent, additional living space for you and your family, but are guaranteed to take your breath away. Getting an expansive loft with Dormer loft conversion

Dormer loft conversion is the most popular style of loft conversion. Apart from the fact that it is more of an expansion of the present roof, it offers a greater amount of additional space than other types of loft conversion. Dormer enables the creation of more head and floor space, leaving you with a spacious room which you can use for whatever activity you have in mind.

Even though dormer conversion provides you with ample space, it can be installed in lofts with limited space or headroom and in addition to that, will provide the top of your home with light and ventilation. Another reason to go with dormer loft conversion is its versatility.

Regardless of the style of your home, whether terraced, end of terrace, detached or semi-detached, dormer loft conversion can be built onto your home seamlessly. Also, with a dormer loft conversion, you have a more harmonious staircase fitting where the new stairwell can be fitted directly above the current one.

Unlike what is normally obtainable with loft conversions, dormer allows the loft to have vertical walls which fit together with a horizontal ceiling, going against the slanted ceiling, just as in the normal rooms of the house.

All these are the reasons why most of our Brighton clients are opting for dormer loft conversions for their homes.

Types of Dormer Loft Conversion

There are a variety of options when it comes to choosing which dormer loft conversion works best for you. Your choice will depend on your budget and whether you would rather have more internal space in your loft or have it be more aesthetically appealing. Some of the more popular styles of dormer loft conversions we install at Clifton Hill & Mont Pelier Conversion are:

Flat Roof Dormer

This is the most popular as well as the cheapest type of dormer conversion in Brighton and the UK as a whole. A Flat Roof Dormer is square with a flat roof that extends straight out from the room, parallel to the ground. This style of dormer loft conversion offers the largest amount of additional internal space, complete with increased headroom, straight walls and flat ceilings. Even though it may not necessarily have the same aesthetic appeal as the other types of loft conversion, it provides the greatest gain in both floor and headroom space.

Shed Dormer

A shed dormer is not too different from a flat dormer. As with a flat dormer, it is rectangular and has one or more windows that extend from the normal slope of the roof. It also features a flat single planed roof which slopes downwards at an angle shallower than the main roof, instead of extending straight out like the flat dormer. It is often used on houses with a gable roof and usually requires a different roof sheeting to that of the main roof.

Gabled dormer

A gable fronted dormer also known as dog-house dormer is a more attractive option which is designed with a gable wall extension built up in existing ridge line and a new roof section built outwards to the new gable end. Gabled dormer is quite popular in residential homes especially for families who need high ceilings. The roof of a gabled dormer has two planes that meet in the centre and slope out on either side. Though it is considered more attractive, it is more expensive to construct and will not provide as much additional internal space.

Hipped Dormer

These types of dormers are characterised by their unique roof with three panes that meet at the top and slope outward. It is considered to be an aesthetically pleasing option and as such is relatively pricey. It is more popular on Prairie or Craftsman style homes.

Pedimented Dormer

Unlike most dormers which are built into the roof structure, a pediment dormer extends away from the roof and must be supported from below using posts and pillars. Because of its dramatic features, it goes best with classical architectural styles so it would probably look out of place in a modern or contemporary home in Brighton.

Other types of dormers we can install in your Brighton home are:

  • Recessed or Inset Rood Former
  • Wall Roof Dormer
  • Eyebrow Dormer
  • Arched Top or Barrel Roof Dormer
  • False or Blind Dormer
  • Oval Dormer
  • Composite Dormer

How do know which dormer style is most suitable for your Brighton home?

With all the options, it must really be confusing picking out a particular dormer style for your Brighton home. You may want something not too bland, yet you do not want to sacrifice space for aesthetics. At Clifton Hill & Mont Pelier Conversion, our expert craftsman will help you pick out the style perfectly suited to your home without you having to compromise on any of your dreams of what of your ideal loft would look like.

Here are some of the factors that would help you select the exact style of dormer you would like us to install for you.

  • Budget: Your budget will play a great role in determining the style of dormer you end up installing in your home. If you are on a fixed budget and intend going for the least expensive yet most efficient style of dormer, the flat roof dormer is your best bet.
  • Artistic appeal: You may want your Brighton home to stand out and intend doing so by installing an attention-grabbing dormer. If your biggest priority is looks, then for that extra pizazz and aesthetic pull, you should go for eye-catching styles such as eyebrow or arched dormer. All designs apart from Flat, Shed or Wall Dormer are known for their high visual attraction.
  • Space: For most people, space trumps all other factors. The major reason they considered installing the dormer in the first place was for extra room and they want styles that would maximise the space. In this case you need more functional space and then Blind and Eyebrow Dormers are not good choices. All other dormer styles will give you as much space as you need but flat, shed and wall dormers make the most of the loft to give you a bigger room.
  • Light: A major benefit of dormer loft conversion is that it provides much-needed natural light, enabling you to use the room for reading, dressing or children playing. Therefore, if you consider natural light as an important feature in your dormer, do not go for Blind Dormer. As the name implies, it does not let in natural light and is mostly for visual appeal.

Will I need planning permission for a dormer loft conversion style?
In most cases, converting a loft with the dormer style or adding a dormer window is permitted and doesn’t require planning permission. However, you have to apply for planning permission if:

  • The home is on a designated land. Examples include world heritage sites, areas of outstanding beauty, national parks and conservation areas. A roof extension does not fall into the category of permitted development if the property is situated within these areas.
  • The materials to be used in the construction of the loft conversion are not in keeping with the appearance of the house.
  • The dormer loft conversion includes a balcony, veranda or raised platform.
  • The dormer extension will face the street or the height will exceed the existing roof.
  • The loft conversion includes a veranda or side window overlooking your neighbour’s property.
  • If bats which are a protected species are using the building.
  • The volume of the converted space is above 50m3 for detached and semi-detached homes and 40m3 for terraced houses.
Will I need a fire escape for my dormer loft conversion?
The dormer window serves as an escape route in times of emergency including fire emergency. Smoke alarms are required for every level of the house, including the loft. They must have a backup battery and wired to the mains in case of a power failure. There must be a protected area from your loft to the ground floor to ensure the occupants evacuated safely.

The fire route has to be protected to withstand 30 minutes of fire. The loft conversion should be complete with a functioning window with non-locking fasteners to ensure a swift exit.

Can I install dormer loft conversion if I live in a designated land?
Yes, you can. Apart from loft conversions, you can remodel or renovate your home if it’s in a designated land such as conservation area. The focus is on preserving the surrounding environment not necessarily the general style of the home.

However, before installing your dormer loft conversion, any work that alters the roofline requires special consent. Failure to obtain the consent means your loft conversion is illegal and you could be fined or even imprisoned in extreme cases.

How do I get the funds to use and pay for my dormer loft conversion?
Funding for your loft conversion can be obtained in the following ways:

  • You can re-mortgage your home. To do this, you must have equity in your home for the amount you need to borrow, including a deposit.
  • If you have savings, you can leverage those to allocate to the cost of a home renovation. Savings is the cheapest way to pay for a loft conversion as you are not charged bank interest. You could also look into a credit card reward or cashback deal to pay off the balance if your savings are not enough to cover the full cost of the dormer loft conversion.
  • You can take out a personal loan if you have a good credit history. It is cheaper than re-mortgaging but you have to consider if you can afford the monthly payments on top of any financial commitments you have.
  • You can pay for your project in instalments. We can sit with you and map out a payment structure starting from the first stage of the project and finishing before the final stages.
What happens to the chimney or water tank in my loft?
If you have a water tank, we can move it to a more conducive area so that you have more space in the loft. We advise Brighton homeowners to upgrade to a combi-boiler that eliminates the problem and provides more efficiency. We can either work around your chimney or remove it altogether.
Will I receive a guarantee?
All Clifton Hill & Mont Pelier Coversions include a 10-year guarantee for your peace of mind.
Do I need fire doors?
When you embark on a loft conversion, it turns your two-storey Brighton home into a three-story building. You will have to upgrade the door to an FD30 fire-rated door. This ensures that your stairs, landing and hallway will withstand 30 minutes of heat when a fire breaks out in any room.
Is the price fixed?
The price for a loft conversion is fixed. We send you a fixed quote detailing the final cost. If you want more than was initially agreed upon, it will come at an extra cost.
Do building regulations apply to a dormer loft conversion?
Yes, building regulations approval is required on any loft conversion in Brighton homes regardless of whether or not planning permission is required. They ensure that the structure is completely safe and will cover factors such as stability, safety, strength and adequate emergency exits. Clifton Hill & Mont Pelier Conversion will help to expedite the process from the application of the initial building notice to the final inspection and will do all this whilst delivering the best service possible.
Do you have insurance?
We have an employee liability and public liability insurance that protects you from liability if anything goes wrong during construction. We are happy to provide documentation of our insurance.

We also provide a 10-year guarantee on all Dormer window installations.

What are the benefits that come with dormer loft conversion?
They provide increased space which means you have room for a closet, en-suite bathroom, reading corner, small window-side sofa and a bedroom. Dormer windows open up space in your room, create more headroom and allow for more daylight. They also incorporate an extra floor of accommodation, turning your home in Brighton into a three storey building without feeling high on the outside. There are many shapes and sizes so you shouldn’t have trouble finding an option that fits your Brighton home.

Some of the benefits that come with dormer loft conversions are:

  • It serves as a potential escape route in cases of emergency. This is necessary in cases where the dormer window is the only exit in the loft.
  • It provides another view to the outside world and also allows natural light into the room.
  • It allows for better ventilation and aeration, more than other styles of loft conversion.
  • It provides extra room and headspace, more than other styles of loft conversion. When a dormer is installed in a bungalow or multi-storey building, the difference in the usable space is significant.
  • They add architectural interest, accent and detail to a home. If you feel that your home is plain-looking, the easiest way to add to its aesthetic appeal and increase its market value at the same time is to add one or more dormers to it. It not only looks good on the outside but also inside and the upgrade will make it easier to sell in case you decide to do so in the future.
What is the difference between planning permission and permitted development?
The difference both is, you need a planning permission if you plan to alter the shape of the roof or if your dormer window is front-facing. You submit your plan to the local council and it is open to rejection by your neighbours or the council.

On the other hand, a permitted development means you don’t have to apply for planning permission. This is usually the case for most buildings that aren’t flats or in a designated area. Semi-detached properties are allowed an extra 50 cubic metres and terraced houses are allowed an additional 40 cubic metres.

Do you build extensions?
We can build extensions at the same time that the dormer loft conversion is being done. Our architects can create extensions that improve the value of your home.
How will a dormer loft conversion add value to my home?
A loft conversion is considered a safe investment which adds value to your property. A large bedroom, with a new staircase, en-suite bathroom and dormer windows deliver an immediately increased value of at least 10%.
How soon can you start the process of building my dormer loft conversion?
We can begin building your dream loft in as little as 2 weeks. It is the same timeframe no matter where your property is based in Brighton. This time frame of two weeks is based on the assumption that all your plans, party wall notices and structural designs are in place. Otherwise, we’ll have to get those settled before starting construction. It might take 2-3 months to get the party wall agreed and plans approved.
Can I use my own plans?
Yes, you can. Our goal is to create the living space you desire so we have no problems using an existing plan as long it corresponds with Brighton’s building regulations.
Why should I work with a conversion loft specialist and not a general builder?
Milosh loft conversion has specialised in loft conversions for a long time. Our certified and experienced architects produce loft conversion designs which maximise your loft space. The in-depth knowledge, planning and design you enjoy with a loft service can’t be compared to a general builder.
I need a dormer loft conversion with a staircase, can you install it?
The staircase is usually the first thing that is completed on your loft conversion. It acts as the gateway to your loft so it has to be done by a professional. Our architect will draw up a plan for the loft staircase and create a fitting design.
Who will supervise my loft conversion?
We assign a project supervisor to your loft conversion who conducts regular inspections to ensure that the work is carried out to our very high standards. They will update you and answer any questions you have.
How long does will my dormer loft conversion take?
The timeframe for your loft conversion depends on the complexity of the work. How big will it be? What is the layout of your home? Are there any special custom designs you want us to add? These are all factors that affect the time it takes to complete your dormer-styled loft conversion. However, it takes no more than 8 weeks for a typical loft conversion and up to 12 weeks for a complex project.
How can I get a quote?
Please call our phone number or complete the enquiry form on our website and we’ll arrange for a surveyor to visit your property.
Do you use eco-friendly materials?
We are aware that most of our clients are conscious of our environment and make use of eco-friendly materials in major aspects of their life. Because of this, we source and use recyclable materials that reduce your carbon footprint.  We could use timber walls, a sustainable material that is a good alternative to brick or concrete. It provides proper insulation and maintains good air quality. It is also cheaper.

We can attempt to reuse your existing roof types or recycled shingles and include double glazing dormer windows that reduce heating bills and provide good insulation. We will also use low energy LED bulbs that reduce electricity bills, illuminate your loft and last longer than regular bulbs.

What is the minimum height for a dormer loft conversion?
The important measurement is the top of the stairs height. The height has to be between 2.0-2.2 metres between the top of the floor joist to the bottom of the ridge beam.
Is a roof dormer practical for my property?
It depends on the type of property that you own as well as your roof frame. A stick-framed roof with a loft has a room for adding a dormer, however, a truss-framed roof does not have any space for dormer installation apart from decorative or false dormer.
