What planning permission do I need for a loft conversion?

So you’re thinking of having a loft conversion – great idea! Loft conversions are a great way of gaining well needed extra space without having to build an property extension. At first the amount of work may seem daunting, especially if you have never overseen a project like this before – that’s were we come in! A Bigger Home is here to do all the hard work for you. We do everything from design, planning and building control, right through to construction and completion. All you will have to concentrate on is the finishing touches to your new living space. First, lets take a few steps back and start at the beginning – planning permission. The first thing you should be thinking about, but do you even need planning permission? Well, Loft conversions are classed as permitted development and do not require planning permission, providing they meet the following conditions

 

  • Any new roofing must not exceed an additional 40 cubic metres of space on terraced houses.

 

  • Any new roofing must not exceed an additional 50 cubic metres of space on detached and semi-detached houses.

 

  • No extension must be made beyond the plane of the existing roof slope.

 

  •  No extension can be higher than the highest part of the roof.

 

  •  New roofing materials need to be like-for-like or close to original fittings.

 

  •  There must be no raised platforms or balconies.

 

  •  Side-facing windows must be set with obscured glazing and an opening 1.7-metres above the floor.

What Planning Permission Do I Need for a Garage Extension?

Extending or converting a garage is a popular home improvement project. However, if this is one of the plans on your to-do list, you might be concerned about whether you need planning permission for it. In this blog we’ll look at this subject in a little more detail.

First, the good news. If you’re enlarging your garage but planning to continue to use it for the same purpose (i.e. as a garage) then you very likely don’t need planning permission to do so. The general rules are that as long as your garage is less than 15 square metres (if freestanding) or 30 square metres (if attached to the house), then you should be good to go (although we always ensure we obtain a certificate of lawfulness on your behalf)

However, converting a pre-existing garage into a habitable living space means there are a few criteria you’ll need to ensure you satisfy under Building Regulations. There are several categories of regulations that will likely apply to your proposed garage conversion.

Let’s take a look at these categories in more detail:

Doors and windows

Your garage extension and conversion will need to have doors and windows that are adequately insulated to avoid heat loss. If any panes of glass are particularly close to doors or the floor, they may also need safety glazing (the Planning Portal has a good rundown of the exact numbers). The size of the room will also affect how much ventilation is required, and this may change if you’re converting your garage into a room that produces a lot of steam, such as a kitchen or bathroom.

Drainage

You’ll need to think about above-ground drainage,  and if you’re planning to connect significant plumbing to your garage extension then there’s also the matter of connecting it with the underground drainage run/local sewer network.

Electrics

Any new electrics you plan to install in your garage conversion will need to be inspected and certified by someone who is part of an approved certification scheme.

Walls

If you’re making significant changes to the external or internal walls of your garage, then there are plenty of regulations you may need to take into account. There needs to be adequate separation between the new habitable space and the remaining space, and there may also be sound insulation issues to consider. If you’re removing a wall, you need to be sure this can be done safely and structurally.

Roofs

This will depend on the extent of the work — if you’re altering less than 25% of the roof area then you are likely fine. However, any major alterations to a roof’s structure, height or appearance will likely mean you need to seek permission from the authorities.

What to do?

And lastly, some more good news. If you’re planning on extending and converting your garage and are worried about planning permission, the best thing you can do is involve a reputable, professional company in your plans as early as possible.

Case Studies: Chafford Hundred

 

The location:

We headed to Chafford Hundred to take on a new brief from a prospective client. A relatively new and desirable area to live in, Chafford Hundred is proving more and more popular for buyers, especially those with an eye on commuting into London. It’s previously been named among the most coveted areas in the country by The Evening Standard, and many of the people who buy there are keen to put down roots and settle permanently. Chafford Hundred comes under the jurisdiction of the Thurrock local authorities in Essex, and any planning decisions will go through them. As you’ll soon see, this would prove important for this particular job…

 

 

The brief:

Our Chafford Hundred customer was blessed with a rapidly expanding family, and found themselves needing a space for the children to play. Of course, big kids need a place to play just as much as little one, and the client was keen that the new space would also be able to house their pool table and running machine. This space needed to serve another function as well — as an extra spare bedroom, where other family members could sleep when they came to stay.

Time to get to work.

 

 

The job:

Fulfilling this brief proved to be a challenge, as there were many different elements at play. We designed a loft conversion in conjunction with not only the architect but also the local authority — a lack of developing rights on the property meant we had to be careful with planning permission and be very sure exactly what we were and weren’t allowed to build.

 

We decided a dormer-style conversion was the way to go, however according to the Thurrock Planning Department, flat roof dormers were out — it’d be against the planning regulations for this particular property. Instead, we came up with a Mansard-style dormer designs, which required us to remove the existing roof and brick up the existing gables. This gave us free rein to create the roof design we had envisioned, build the Mansard-style dormers, and fulfil our client’s brief.

 

 

The result:

A great success. The client’s growing family use the new space daily, and the extra space goes a long way towards making this house feel like a proper family home. Thanks to our careful work with the planning authorities, it’s all above board as well.

 

Job done. Onto the next one…
