The loft conversion process

Any kind of loft or roof conversion is an incredible way to maximise the space in your home using facilities you already have, boosting your property value and improving your quality of life all at the same time.

We offer specialised and tailored services designed to fit you and your unique needs perfectly, offering expert advice and guidance the whole way through the conversion process.

This ranges from us helping you to choose the builder and outlining contracts through to regular site checks and using us as your communication point where required to prevent any disputes.

Design considerations

When beginning the design process, there are two things to consider carefully. They are the height after conversion and the impact any stairway will have on the floor beneath.

You are required to have a minimum of 2.4m head height (from top of the ceiling joist to under the side rafter) in the conversion, and building regulations require a minimum of 1.9m over the existing flight of stairs to prevent collision.

Bathrooms and en-suites will need further careful design as the connection to water and waste will need to be considered as well as the previous points too.

The internal height is always a factor to remember too, as the angle of the roof sometimes makes it difficult to see where you can stand and place the stairs.

Quite often an engineer will need to design and calculate any changes that might need to be added to the wall loadings and roof timbers, but this is something we can help with as well in the process.

Finally, we can then look at further options with the layout to help you get the perfect space to suit. We’ll work with you in every aspect of this to make sure it’s exactly what you want with as little compromise as possible.

We update you every step of the way through the entire project

Planning permission

Planning permission is something that needs careful consideration with any renovation. A good thing about converting the loft is that it can sometimes be converted under permitted development, and even roof extensions and dormers can be done this way.

It is possible to add up to 40 cubic meters on a terraced property or up to 50 cubic meters on detached and semi-detached properties.

Even if you do need planning permission, with careful design and consideration, we can make it work with the character and style of your home which gives the project more chance of success.

When it comes to helping you achieve the extra space you want, CK Architectural will always offer the best advice.

Building regulations

Legally, Building Control need to be involved when altering the structure of a roof and building certificate 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:

  • Structure, the new floor joists and roof will need to be supported; this is 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.
