If you're in need of extra space in your home, a loft conversion is considered the most cost-effective answer. But there are many different types, so which style do you go for? And is it worth the cost and hassle?
Moving home isn't always an option and involves a lot of upheaval, stress and hard work. This makes getting an extension or loft conversion on your existing house an attractive idea, but how practical is this? And what is involved?
As trusted and experienced professionals in this field, Loft Crew can cut through all the uncertainty and help you discover the best solution for your property, circumstances and budget.For some customers, a side dormer loft conversion will be ideal, and our experienced team will soon make this a reality.

Basically, side dormers are a specific type of dormer* extension built onto the side of your existing roof, as opposed to the front or rear. This involves raising the side roof slope so it projects vertically to create additional 'head height' and living space within the loft.
They can be constructed with either a flat roof or a pitched roof, depending on the overall height of the loft conversion.
*Dormers, also called dormer windows, are fairly simple structures where a box is constructed in the existing roof slope, usually with a Velux window and vertical walls. These can be very basic, although there are many different types of dormer extension to choose from that are more elaborate (find more details below).
See why hundreds have trusted us with their loft conversions. Minimal disruption, maximum satisfaction.

Side dormers are better suited to houses with a hipped roof as opposed to a flat gable end. A hipped roof is one that has four slopes running down from the ridge line in a sort of pyramid shape.
If your home has side-facing roof slopes, then it's a good match for one of these amazing conversions.
If you're unsure, we will check your property out to see which type of loft conversion would be best.


A side dormer conversion offers several advantages that make it a compelling option for homeowners looking to expand their living space:
Unlike smaller dormers, this type makes the most of the often-unused side roof slope, adding more usable space to your loft compared to other types of conversions.
The vertical extension creates a spacious and comfortable living area with plenty of headroom to move around freely.
Well-placed windows on both the front and side walls of the dormer flood the loft with more natural light, creating a bright and airy atmosphere. Studies have shown that natural light plays a crucial role in boosting mood, energy levels, and overall well-being.
The rectangular or square shape of a side dormer provides a blank canvas for creating various room configurations. Tailor the space to your needs, whether it's bedrooms, bathrooms, home offices, or open-plan living areas.
Adding functional living space through a well-designed dormer loft conversion can potentially increase the value of your property, making it a worthwhile investment.
The dormer conversion adds a unique and eye-catching feature to your house, potentially enhancing its kerb appeal and character.
You can choose between a pitched roof that blends seamlessly with the main roof or a flat roof for a more modern look, allowing you to customise the visual impact.
With windows on multiple sides, side dormers facilitate natural air circulation, creating a healthier and more comfortable living environment.
Depending on which side you choose, your loft can offer charming views of your garden, the street, or the surrounding landscape (if you are fortunate enough to have a great view!).
Volatile house prices, stamp duty, the stress of finding a buyer, the 'chain', house sales falling through -the trials of moving house are well known to millions of people, and selling up is not a decision to be made lightly! All this makes the idea of a dormer loft conversion very attractive.
This is your space, so it's up to you how you use it, and the possibilities are almost endless! These are highly versatile spaces that can be used in many different ways.

The three main factors here are size, location and design.
In our experience, the majority of loft conversions go ahead without the hassle of planning permission, but only if your project complies with the Permitted Development rights.
Under the Permitted Development rules, your loft conversion design must not exceed a certain size; 40 cubic metres for terraced houses and 50 cubic metres for detached or semi-detached houses.
Also, to comply with regulations, the dormer cannot be taller than the highest point of your current roof, must follow the angle of the existing roof slope at the front, and needs to be built at least 20cm away from the edge of your roof (eaves). The loft conversion must also not impact the 'principal elevation', meaning the most prominent facade as seen from the road. In simple terms, this is the front of your house.
One way to potentially avoid planning permission is to apply to your local planning authority for a Lawful Development Certificate, as this will decide whether the conversion is lawful. It also provides you with evidence that the conversion meets all legal planning requirements.
More details here in our post “do you need planning permission for a loft conversion”.

With terraced or semi-detached properties where you share a wall with neighbours, a Party Wall Agreement may be necessary. This is a formal document drawn up between adjoining property owners when building work needs to be done near or on a shared wall, known as a "party wall." The agreement outlines the rights and responsibilities of each owner, ensuring fairness and protection throughout the construction project.
More information here in our post “do I need a party wall agreement for a loft conversion”.
Listed buildings or houses within a conservation area may have strict limits placed on any renovation work. We will assist you, if necessary, in liaising with the local authority or relevant body to confirm the precise terms.
Finally, whether you need planning permission or not, your loft conversion will require building regulations approval. Throughout every stage of the process, we will adhere to all safety procedures and building regulations to ensure that you get the best quality. This includes the initial inspection of your roof structure right through to checking your new loft stairs (and everything in between) to make sure they meet the required standards.

If this style isn't the best match for your property, we may be able to suggest another.
Here are some other examples:
Each one has its own distinctive style and is suited to specific types of houses.
