You’ve seen our beautiful HAB’s, you’ve fantasized about how you’re going to do it up and make it yours, but you’re not sure what hoops you need to jump through in order to get your pre-fab HAB attached to your home.

One of the major hoops to jump would be in the form of that beautiful process of obtaining planning permission. So, let’s take a look at how this affects your ability to get your dreamy new HAB.

What is Planning Permission?

In order to build on land or change the use of a piece of land or building, you need to have planning permission. Basically, you’re asking if you’re allowed to do certain types of building work and your plans will either be granted or denied depending on a few variable factors.

The responsibility for granting and denying planning applications is usually down to the planning department of your local council as each area of the UK can have rules unique to them.

It is always your responsibility to seek planning permission or hire a contractor that includes this process within their services, planning permission should be granted before any work begins.

Do You Need Planning Permission for a Pre-Fab Habattach Extension?

So, where does that leave you with wanting a Habattach extension then? When we set about designing our HAB’s during the development stage, we felt it was important to make the process as accessible and simplistic as possible without compromising on the quality of the structure.

Our strap line is ‘fixed cost, fixed design, fixed install time’ and it’s something that we’re really quite passionate about. By using a pre-fabricated construction method, the manufacturing of the HAB happens with the supplier, the pieces are delivered directly to site and installed onto the home by our team of HAB experts. Because of this pre-fab method, we have to stick to a fixed design, we poured a lot of heart into what our HAB’s will end up looking like and the feedback we’ve had has been nothing but positive! 

So, we know what each HAB will look like, which means we know the exact measurements and materials that will need to be used for each HAB too, this is where we can affix both the fixed cost and the fixed install time!

All of our HAB’s were designed to sit within building regulations and permitted development, but what does this mean?

Starting with an example of our HAB’s being designed to fit building regulations: With some extensions such as conservatories or orangeries, you need extra permissions due to the lack of thermal efficiency that these types of structures can have. It means that in the vast majority of cases, you’ll have a door separating your conservatory, for example, in order to make sure that you’re not expending extra energy in your home trying to heat up a space that is losing heat quicker than you can get it in there! We use high quality, efficiently insulated materials to build each of our HAB’s to avoid this issue. It means that should you choose to completely open up your home to include the HAB and have one big seamless space, you can. 

Now let’s look at permitted development. First of all, what is it? Permitted development is an act passed by the government to allow certain bits of building work to be completed without having to gain permission beforehand. It’s a handy little tool that allows a homeowner to make changes to their home without the rigmarole of paperwork and telephone calls. Some of the types of work that typically fall under permitted development are: porch, internal alterations, loft conversion, roof lights or dormer windows, extension to the back of the home (within reason). Most of these examples apply to houses and are also a general overlook of what could be included, we always recommend speaking with your local authority before any building work starts.

Of course, the size, shape and design of our HAB’s all fit within the basic parameters of permitted development. As with anything, there are things to consider beforehand and these mainly lie with if you were to live in a protected or conservation area or a listed building, in these cases you will need to apply for planning permission as permitted development will not automatically cover you.

With each HAB enquiry, we offer a site survey before any work takes place, this is where our expert team will tour the property, mark out where the HAB would go and discuss whether we felt that your project would need to have prior planning permission. If it happens that you do need planning permission and are desperate for a HAB, we will then build this into your agreement and assist in the acquiring of planning permission.
