Garage Conversions In The UK - At What Value

Most conversion works to an existing structure is often more expensive than having it knocked down & rebuilt. The main reason for this is the VAT element that is exempt for new dwellings. There have been numerous examples where extensive extension & conversion work has proved more expensive than rebuilding the scheme a-fresh from the ground up.

However, where VAT is still applicable even for new build within an existing residential curtilage, the conversion route is often still less expensive. This can also have the added benefit of retaining the sites character & charm where as a complete new build can often stand out like a sore thumb.

Garage conversions are a case in point. Converting a domestic garage (normally integral or attached to the main dwelling) is a growing trend that I cannot see declining in the coming years.

Peoples desire for additional living space is by far more important than the the requirement to store a motor car or general household storage which is more often the case.

WIth the general superior build quality of most modern day cars the need for undercover parking in order that they start in the morning has now diminished. This combined with the relative cheapness of cars makes that valuable garage area look very under used.

Off road car parking is till very important but a physical building to store it in overnight in is not.

So what are the issues relating to converting an existing garage into habitable room space? Well firstly, most garage conversions do not require the benefit of a separate Planning Approval unless there is a condition on the original Planning Approval restricting the garages use. Always check with your Local Planning Authority first but in most cases specific Planning Approval should not be required (subject to conditions & Planning criteria).

If the garage is to become a useful additional to the main dwelling then it should ideally be converted in a way that makes it hard for the 'lay person' to tell that the space was originally a garage.

This means that the new room (previous garage) should be preferably accessed off the main hall way, have follow through floor levels (rather than step downs), have similar floor to ceiling levels, have all the meter services relocated to outside meter boxes, be centrally heated, thermally upgraded for the floor walls, & ceilings, & have a quality in-fill construction for the old garage door opening. Most of these items are covered within the Building Regulations for which the conversion must comply also to.

As a guide, a good single garage conversion incorporating these element will be in the order of £15 to £20K. Cheaper conversions can be achieved but they will always feel like a 'converted garage' & may not add the full value to a property.

If the converted garage can only be accessed off another room such as the living room or kitchen, they can still perform a useful functioning extra room but they
