Loft conversions are often the most budget friendly, time effective and efficient form of home renovation, and CK Architectural offers designs and project management for you to get one that’s perfect anywhere across the whole of the York and Harrogate areas.
LOFT CONVERSION OR DORMER ROOF EXTENSION
If you are planning on adding a room, a loft conversion could be the cheap and easy way for you to do it. You already have the space, so why not make good use of it? Getting the most out of a loft conversion requires a lot of thought and careful design, and that’s exactly what our specialist design team can offer. Master bedrooms with en-suite and dressing rooms, cinema and media rooms, children’s rooms and even more can be achieved with good architectural design.
Depending on what your reasons for wanting are though, you have a range of options available to you to get the best fitting design. Dormer loft conversions are ideal for more head room and more active purposes. Bedrooms may fit roof extensions better though, alongside en suites or even Juliette balconies. For anything else, the standard may already be perfect.
We work with you and not just for you to really make sure you’re finding your perfect fit, and we’re always striving to create a design you’ll love for years to come.

LOFT CONVERSION CONSIDERATIONS
When we begin creating designs for your perfect loft conversion, there are a few design considerations that need thinking about first, which is why thinking about what you need from your conversion is always step number 1.
The height and pitch of the roof are the first things we need to consider, since this effects how much room will you have to stand in when the conversion is complete. You need at least 2.4 Meters height in the apex of your existing roof, as the new floor joists and rafter insulation will eat into the height. When you have determined the height you’ll need, the stairs need to be designed at the right pitch, protected from fire, and the with landing areas all catered for.
Once the necessary elements have been designed, you can divide up the remaining space. If you’re having ensuite, the drainage needs to be thought about as you can only go so far through the new floor. Also, 2nd floors or rooms with a finish floor over 4.5 but under 7.5 meters need a sealed/protected landing top or bottom. Creating rooms over 7.5 meters will require a lot more fire protection, escape and detection.
Sloping ceilings can be challenging to work around, however when you can make full use of the triangular profile, they will look spacious and add a lot of interesting features. Laying out furniture such as beds wardrobes in cross section helps to see the volume you will get. Adding dormer can create extra space and add feature to the external roof too.
Be careful when choosing the material finish outside, as sometimes the small dormer side/cheeks will look best if you try matching the tiles. The dormer is different as you can’t always blend it in, so consider finishes that enhance the angles and make if prominent and purposeful. Velux windows are the most obvious way to light in with most of these options. Other options are building up the gable, forming hip dormers and in some situations putting a new roof on.
NO FEES UNTIL YOUR PERSONAL DESIGNS ARE READY
Under the new permitted development right, most roof conversion can be done without the need for planning permission. If planning is required, the usual criteria and justification will have to be met.
Overlooking, dominating, keeping in character, size and scale to its neighbours will be the main things to consider.
We will consider all planning policies, both national and local, before you submit anything to ensure that you have the very best chance of success.
PERMITTED DEVELOPMENT LOFT CONVERSION
A roof or loft conversion for your house is permitted development, not requiring an application for planning permission, if the following limits and conditions are met:
- A volume allowance of 40 cubic metres additional roof space for terraced houses.
- A volume allowance of 50 cubic metres additional roof space for detached and semi-detached houses.
- No extension beyond the plane of the existing roof slope of the principal elevation that fronts the highway.
- No extension to be higher than the highest part of the roof. Materials to be similar in appearance to the existing house.
- No verandas, balconies or raised platforms. Side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor.
- Roof extensions not to be permitted development in designated areas.
- Roof extensions, apart from hip to gable ones, to be set back, as far as practicable, at least 20cm from the original eaves.
- The roof enlargement cannot overhang the outer face of the wall of the original house.
BUILDING REGULATIONS FOR LOFT CONVERSIONS
Legally, Building Control need to be involved when altering the structure of a roof, and a building certificate is required for the re sale or insuring of your property. When creating habitable rooms like bedrooms, it is more than the structural integrity that will need upgrading. When designing a roof, your architect or architectural designer must consider the following:
- The new floor joists and roof will need to be supported, generally done via steel beams designed by an engineer.
- A protected fire route must be provided, this is 30 minutes all the way down to the final exit, existing doors will need upgrading to fire doors.
- Detection and sounded alarms will be required and need to be interlinked.
- The stairs will need sufficient headroom 2.0M and not be too steep (under 42 degrees).
- Reasonable sound insulation between the conversion and the rooms below
All the designs we present to you will be with the intention of passing building regulations and construct able. Take a look at our Building Regulations Guide for more information.
WE UPDATE YOU EVERY STEP OF THE WAY THROUGHOUT THE ENTIRE PROJECT
BUILDING AND BUILDERS
Once you have your detailed drawing approved, it’s time to get some builder prices to get the work completed. We offer project management services to do all of this for you, and we can also recommend you builders that we trust if you choose to manage your own work. There are specialist roof conversion companies out there, but with detailed drawings most competent builders can do the job.
Most of the work in roof conversions is in the roof, however, when the new stairs go in, there will certainly be a dirty period when it advisable to move out if you can. We advise that any quotation you consider will be written up clearly and well detailed. Both you and your builder need to know exactly what is included in the price or disagreements will occur at the messy end of the project.
We have extensive on-site knowledge and work closely so we will always advise where we think areas need exploring or issues may arise. We advise that you use our drawings in line with the quotation and any additional information we don’t provide such as plumbing and electrics is agreed in detail before the first fix goes in. it will be costly changing thing once the initial preparation has been built. We offer help throughout for both you and the builder, we will come to site if help is required.
