One roof space conversion cost is not the same as the next. So, it is pointless to ask how much your attic conversion will cost. It will depend on many different elements, and no two conversions are ever the same. Instead of asking how much your conversion will cost you can break down the cost into sections. This way, you will not forget and elements and hidden costs will no longer be a problem.
Roof Space Conversion Cost : How Much Will you pay
How much you will pay for your roof conversion will depend on your roof structure, on whether any structural alterations need to be made, and of course on the size of the existing space. It will also depend on what windows you will add, if you need to make alterations to the lower levels of your home, and what type of staircase you opt for. It will also depend on whether you are going to try a DIY conversion or call in the experts. We highly recommend you do not try a loft conversion yourself.
Roof Space Conversion Cost : Basic Attic Room
The most basic loft conversion where no window is added can still cost a frightening amount of money. In fact, you will rarely get change from 15K. Included in this estimated amount is the reinforcement of the floor, insulation, and a couple of basic skylights. Included in this price you will also be provided with a staircase, lighting, heating, and electric. When you use loft conversion experts for the job, the conversion will comply with building regulation and will also include smoke alarms and fire doors.

Roof Space Conversion Cost for Dormers
Dormer conversions are common, and they do not require huge amounts of extra work. The introduction of dormer windows will mean you will gain usable floor space and head height. You will also have more options open to you when you are choosing your stairs. A basic dormer conversion will cost at least 20 thousand pounds, but could easily cost as much as 45 for a double bedroom with an en-suite bathroom.
Roof Space Conversion Cost : Raising the Roof
The price of your loft conversion will quickly escalate if you need to change the roof structure. This type of construction will also require planning, planning application costs adding to the final bill. Designers fees will also mean you will pay more, the work carried out also being far more difficult than a standard conversion. This type of conversion will cost anything upwards of 40K.
Ready Made Loft Rooms
One option open to you is to have a readymade loft room created for you that will then be craned into place. This is a viable option that will mean you can avoid the long task replacing rafters and it is indeed quicker than replacing them and rebuilding the roof. A scary option, the top of your home will literally be lifted off! This choice is not the cheapest however, with scaffold hire and other labour costs adding to the bill. You are looking at a minimum of 50K for this type of roof conversion, and a project that is not for the feint-hearted.
Insuring your Loft Conversion Work
Whether you need to take out insurance yourself, or if it will be provided by your loft conversion experts is another important factor that will contribute to the overall cost. Conversion insurance will be needed if you are managing the overall project yourself. If there is a party wall, then you could meet with further complications. Hiring a professional team from the very start can mean you avoid these extra costs and also worries.
Your existing building insurance will also become invalid if you change the structure of your home. When you are planning your loft conversion you must contact your insurers to let them know of your plans. Once your conversion is complete, then a new annual premium can be set. Any damage to your existing build caused by works carried out will not be covered by your existing insurance. This is another reason to ensure you take out an extra policy.
