If you want to add space and value to your home, a loft conversion is the best way to do that.
But how do you know if yours is suitable for conversion?
If you’re considering converting your loft into a home office, a new master bedroom or a games room for the kids (big and small), keep reading.
What are the requirements for a loft conversion?
A loft conversion doesn’t need to be complicated, but there are several things you need to consider before you begin:
Do I need planning permission?
Most properties come with a permitted development (PD) allowance, which means you can convert your loft space without planning permission. However, you may have to adhere to certain parameters, including:
- Your home must not have used its PD allowance to build an additional storey.
- The loft conversion mustn’t exceed the height of your existing roof.
- It cannot extend beyond the roof slope.
- Balconies with a raised platform are not allowed under PD, but Juliet a balcony is.
- For mansard loft conversions, you’ll need planning permission.
- Loft conversions are not considered PD in Areas of Outstanding Natural Beauty and conservation areas.
- PD for loft conversions in some areas may have been removed, so check before you get started.
- Apply for a Lawful Development Certificate. You’ll need this if you ever decide to sell the property.
Is my loft suitable for conversion?
Even if your property has permitted development (PD) allowance, there are some more stipulations, depending on property type:
- Terraced housing: development cannot exceed 40 cubic metres.
- Semi-detached housing: development cannot exceed 50 cubic metres.
Also, not all lofts are suitable for conversion. Some will require extra structural work or a certain type of loft conversion to meet specifications.
Do I need to work with an architect?
Although you can design a loft conversion yourself, using an architect or designer is advisable.
However, remember this will add to the overall cost of the project.
Does roof structure matter?
It does.
Your roof will either have trusses or rafters:
- Rafters: run around the edge of the roof and leave most of the space below hollow.
- Trusses: run through the cross-section of the loft. Converting lofts with trusses is possible, but extra structural support is needed, making conversion more costly.
Rafters are better for conversions, but there are ways around it should your roof space have trusses.
What is the minimum head height allowed?
The minimum height needed for a loft conversion is 2.2 metres.
If the head height is less, you may have to add a mansard roof or replace the roof and structure entirely.
Will a loft conversion affect the foundations?
Adding a loft conversion will put extra stress on the foundations of your home. To check yours, speak to a builder about digging a trial hole to expose the foundations and bring in a building inspector for extra guidance.
Things to consider when designing your loft conversion.
Getting the go-ahead is exciting, but there are several things you need to think about during the design stage:
1. Insulation and heating
Will you need to heat or insulate your loft?
If it needs heating, consider where radiators will go – or if underfloor heating is possible. You’ll also need to consider upgrading your boiler if you’re adding a shower or bath.
Insulating your loft is always advised regardless, as it makes your home more energy efficient, reduces costs and adds value to your property.
2. Loft stairs
Even a space-saving staircase will take up a significant chunk of a room. So, factor in the changes you’ll need to make on the floor below, like:
- Where the staircase will go
- How much room it’ll take up
- What space you’ll need to lose
- The headroom need
- Fire safety
How long does a loft conversion take?
The average loft conversion project takes around eight weeks to complete. However, more complex renovations may take longer.
How much will a conversion cost?
With all the above in mind, it’s understandable you’ll want to know how much a loft conversion costs before you start the whole process.
A typical loft conversion can cost anywhere between £18k and £65k.
Like anything, the cost will depend on the type of conversion you want and how complex you want it.
