How you can make the most out of your space in Hertfordshire?


As one of the most straightforward loft conversion types, it also proves to be the most economical. Without changing the shape of your roof, the Velux windows can be fitted onto any gradient and will allow natural light into the new space, reducing the amount of artificial lighting you would need to have installed. As the roof remains unchanged, there is usually no need for planning permission.

Single Flat Roof Dormer

As the most popular choice, this conversion will allow enough space for a bedroom and en-suite up to 50m3. Most commonly used on terraced or semi-detached properties, this loft extension is suitable for all house types and planning permission is not usually required as this is a permitted development.

Gabled Dormer

If your Hertfordshire home has a pyramid style roof or is on a conservation area, a rear hip to gable dormer may be possible depending on planning permission.

L-Shaped Dormer

Commonly occurring in Victorian terraced and semi-detached houses, the already sectioned loft can be transformed into two bedrooms and a bathroom totalling 70m3. By adding an additional storey to your home without expanding your footprint and are making a great investment in your Hertfordshire home.

Mansard Dormer

Popular in Victorian flat-roofed terraced houses, these loft conversions typically have brick gables and a 70° front face of the dormer. Without being overbearing and working with a flat roof type, they are by far one of the most spacious and eye-pleasing loft conversion types.

Hip to Gable

A hip to gable conversion enhances your home by adding a much larger roof space to work with, creating a spacious loft conversion. Once again, it is unlikely to require planning permission as this type of conversion is classed as a permitted development.

Low Pitched Lofts

At Touchstone Lofts, we pride ourselves in converting a loft where others can’t.  Architects and other builders would usually dismiss a low pitched loft, but by using our previously used, tested and successful strategies we will be able to complete your conversion to a high standard. As expected, this type of conversion would be more technical and will require planning permission in most instances.

Pitched Roof Dormers

Pitched roof dormers are available in a range of styles, providing greater freedom when tailoring your loft conversion to your property and requirements. In order to be pleasing to the eye from the outside, a small amount of space inside the loft is compromised, but the overall look is less noticeable to passersby, which is ideal if you are looking to hold up an attractive and elegant image of your Hertfordshire home.

How does the loft conversion process in Hertfordshire work?

We provide a fully inclusive, one-stop service, meaning you won’t need to worry about seeking any other trades. From designing and building, through to plumbing and tiling, we will do it all. We will initially meet with you at your home so that we can hear your requirements and ideas and can pass on our thoughts on what is possible with your loft shape. We will sketch up a free design, usually costing £600, to give you a preview of how your home will look at the end of the process and give a ballpark quote. We aim to have every loft converted and completed to a high standard no matter how complex. You will be able to continue living in the property throughout the process and we will carry out the work with minimum disruption and mess.

Your loft conversion questions answered

Have a question about loft conversions? We’re happy to help. Read our answers to the questions that our customers frequently ask us.

How long does a loft conversion take?

Depending on the size and type, most loft conversions take around 12 weeks.


Will I need to move out during the project?

No – it’s safe to carry on living inside the property. We work from the scaffolding before the stairs go in. Any disruption you experience will mainly come from noise.


Where will you place our new staircase?

We will be able to fit your staircase around your existing layout and will find an option to suit you. If possible, we will try to fit your new staircase over the existing staircase so that it fits seamlessly within your property.


Do I need planning permission for a loft conversion?

This depends on your location and type of property – all flats require planning, but if you live in a house that isn’t in a designated area, then permitted development is usually used and no planning is required. There are many other factors to take into account and one of our surveyors can advise further.

How much does a loft conversion cost?

Most cost between £30,000 and £50,000. This depends on the size and type – bigger and more complicated jobs take longer and therefore will cost more. See pricing information for further details.


What is a party wall agreement and do I need one for a loft conversion?

A party wall agreement (PWA) is required if you have a semi-detached or a terraced property and you are working within or near your neighbour’s boundary. We can advise when the surveyor visits.


Does a loft conversion add value to a home?

Yes – it will add from 20% to 30% upwards depending on the size, design and type.


How much head height do you need for a loft conversion?

If you have a clear head height of 2m then a loft conversion may be possible. Our surveyor will need to assess this to confirm.

Where will you place the new staircase
