Costs to consider when extending your loft - key things to consider

If you have chosen or need to convert to space in your loft, then you will need to consider the costs that could be involved.  There are two options to take depending on the viability of your roof space.
 
Option 1 – The basic conversion
Building regulations stipulate that the loft space needs to be greater than 2.2 metres – this is measured from the loft floor to the rafters above.  If your house meets these requirements, then the following costs could be incurred and will need to factored into your overall budget;

• Electrical fittings – lighting and power will need to be included as part of the building work
• Water tank relocation – many homes might still have a water tank is located in the loft.  This will need to be relocated or for an additional cost, you might want to get a combi boiler installed which would eliminate the need for the water tank.
• Floor reinforcement – Loft floors aren't naturally designed for heavy foot traffic, and if your loft conversion will be a new room, then that's exactly what you'll be creating.  Therefore, the floor will need to be reinforced.
• Stairs to the new room – you will need to be able to access the new room without climbing up the old loft ladder everyday.
• Insulation – Heat rises and therefore, your loft will be quite cool.  In order make it a serviceable room, you will need to have insulation added.
• Health and safety regulations – All houses, extensions and loft conversions must meet fire and safety regulations.
• Windows – most often because of the shape of the roof, these are skylights.  They will need to be properly and securely fitted to avoid leaks.

 
Option 2 – Raising the roof
If your roof space doesn't meet the height regulations, then you could consider having the roof raised.  This option is the most expensive because you will have to have your entire roof removed and rebuilt at the new higher level.  In addition to this, you will also need to apply and successfully get planning permission, which could take a while.  Once the new higher roof has been constructed, you will then incur the same costs as outlined in Option 1.
 
 
It is important to considered and budget for all possible costs when planning for a loft conversion.  You will also need to ensure that building regulations allow for the conversion and that the roof meets the minimum requirements before embarking on any such work.
