London Loft Conversions

Put your loft space to use: create extra bedroom or study, en suite bathroom or shower room, or even simple storage- there is no such thing as too much storage. Loft conversion will definitely add space and value to your home.
Thanks for visiting our webpage and lets see how to get your loft conversion started.
Feasibility- Can I convert my loft?
It is always a good sign if your neighbours have converted already. It almost certainly means that you can also convert your loft. If you don't see roof lights and dormers(raised roof structure usually at the rear) call us in and we will advice. What we will check for is a number of things: the type of roof structure, floor structure, headroom, staircase position, any heating system elements such as tanks, at the same time we will take a note of your requirement. At this point we will also supply you with design and typical build cost.
Re Planning permission, party wall agreement and Building Control please see the question section at the bottom of the article.
Cost - How much is the loft conversion?
This is tough question as it so depends on your loft structure and what you want to achieve. Here are the options and indication for each option assuming typical London terraced house:
Types and estimated costs of loft conversion
Use your loft as a storage (not habitable room):
This is simplest and cheapest conversion we will usually reinforce the floor, lay the chipboard flooring, wire up some light,  and install hatch and pull down ladder. This is quick makeover can be done in a week and will cost you ~£2k including materials
You also may require floor reinforcement, some wiring(light and power), insulate, close the ceilings, install some roof lights to let in the light.
Velux / skylight / roof light : cost effective and very simple
This conversion involves adding roof light windows to the existing roof, with no need for further building. This is ideal if you have a spacious loft with plenty of headroom, and is simple to carry out.
It’s generally cost effective and quick to complete. Typically, planning permission is not required for this type of conversion, as it falls under permitted development, though check with your borough to see what’s permitted.
Typical cost: £20k
Dormer : a versatile and popular way to create extra space, in a cost effective way
If your loft doesn’t have much headroom, a dormer conversion is a great solution.
This involves building a box-shaped extension to the slope of the roof. It can create a lot more space, which offers greater versatility in the function of your loft conversion. It also gives you more flexibility on the location of the staircase, and the increased footprint should give you enough space to add a bathroom.
It’s simple and cost effective to construct, and there’s minimal disruption. Planning permission is not usually needed for dormer conversions, but check with your local authority.
Typical cost: £30k
Hip-to-gable : increased space with a side roof extension
If you have a roof with a sloping (‘hipped’) side, you can add more space by converting it to a ‘gable’, which involves turning the slope into a vertical wall up to the height of the roof ridge.
These are suited to end terraces, semi detached or detached properties. It involves rebuilding part of the roof, but there’s normally no planning permission required. However — as always — do check with your local borough.
Typical cost: £40k
Mansard : elegant, much more space, and suitable for many types of properties
This type of roof style dates back to 17th-century France and is a stylish solution that increases the space of your loft significantly.
This type is suitable for a wide range of property types, and involves creating a much steeper slope for the roof (usually at the rear due to planning restrictions), with gable windows. A mansard conversion results in a lot more space, so you have many more options over the usage of your loft.
The increased footprint should also give you space to add a bathroom.
As this style requires more work to the structure of your property, planning permission is usually required. We can advise you on this.
Typical cost: £45k
Cost overview:
Storage £2k
Roof light: £20k
Dormer: £30k
Hip-to-gable: £40k
Mansard: £45k
Bear in mind cost varies according to scale and choices, so these are simply guidelines.
Potential add ons costs for conversion:
if you need to move the storage tank and convert your heating system, add £1000.
If installing a bathroom, add £5-7k.
The fittings you choose will also affect the cost — for example, whether you choose PVC, wood or aluminium-clad window frames. This applies to floor and wall finishes, electrical fittings etc.
If you’re planning to have a bathroom installed, this will add around £5,000 - £7,000 to your budget for cost of sanitary ware and installation.
Any built in joinery to be added?


How long does it take?
Storage it is a week or two.
A Velux / roof light conversion typically takes 6 weeks.
Other types of conversion take around 8-12 weeks depending on the scale and complexity of the project.
Do I need to move out?
No, you don’t need to move out for a loft conversion.
Legal side of things
Do I require Planning permission in case of storage and roof light conversion no, for the rest of more extensive build- yes  you will need to gain permission first.
Party wall agreement you will have to inform and agree with your neighbours or employ Party Wall surveyor if there is a dispute or you want to deal in more formal way
In most cases you will need to inform Building Control of your plans, they will assign officer to look after your project. Once all complete to Building Control officers satisfaction you will receive compliance certificate.
