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.

We also offer a project management service to help you carry out your project with efficiency and accuracy to minimise stresses and complete to project with the utmost care. 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.

Loft conversion permitted development rules

1. No extension beyond the plane of the existing roof slope of the principal elevation that fronts the highway.

2. No extension to be higher than the highest part of the roof and similar materials.

3. No verandas, balconies or raised platforms.

4. Side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor.

5. Roof extensions, apart from hip to gable ones, to be set back at least 20cm from the original eaves.

6. The roof enlargement cannot overhang the outer face of the wall of the original house.

7. Roof extensions not to be permitted development in designated areas such as AONB (area of outstanding natural beauty), conservation areas, listed building etc.

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.

Highly recommend CK Architectural. Chris and his team did a great job gaining planning permission for a new build and renovation of an existing property. We hit some dead ends with the planning officer but Chris found different ways of getting around the problems without going over budget.

For someone far removed from the building / planning industries the thought of where to start when thinking of a big extension project to my house (two story to the side and wrap around of semi-detached 3 bed) was a little daunting at first. Luckily, after obtaining a competitive quote, I enlisted the services of CK Architectural and have been very impressed with not only the service received but the ease at which they have made the whole process. After listening to my thoughts and the reasons for needing the extension work doing, the architect came up with a great design that encompassed everything that was needed. Even when I changed my mind over a couple of aspects, Donna, Chris and the team were quick to administer any alterations. Every visit to the house for measurements / planning etc has happened without a hitch with all members of the team we've encountered being punctual and professional at all times. The best thing has been by far the ease at which CK have made of getting all council and local authority sign off for the project. All I have needed to do is pay the fees at the required time, no stress involved and all went through seamlessly. I'm now at the stage where I have the drawings to hand and have submitted them to builders to obtain quotes. Importantly, the feedback so far from the builders indicates the project to be within the budget specifications I explained to CK during the first consultation. Very happy customer 🙂 Carl.
