For those who have an rarely used garage area, why not look at a conversion in Harpenden to make the most from your house. Take a look at around 4 free quotations with our service and find the top price for a conversion.
One of the main benefits with a garage conversion is that the space can be converted quickly for the extra room you'll need, regardless of whether it's for a growing family or simply to add to the value of your property.
A garage conversion means you won't have to move for more space, which will help save a lot of money on solicitor charges, estate agent payments and stamp duty. And the extra space could be transformed into what you need, whether it's an extension to the living area or kitchen, or simply a separate room completely.
With the infrastructure already in place it's evident that a garage conversion will be cheaper than building an extension also, and won't consume valuable space within your garden. With the outside not likely to change as well, it's a good way to get around regulations for conservation areas and listed buildings.
Should you be keen on transforming your garage, review quotes from companies within Harpenden making use of our quick service to obtain the best deal available.

You may need planning permission if you are planning a larger extension. All extensions will need building regulations approval. An architect can assist with this and if planning permission is required. A reputable contractor will also be able to advise you if this is needed as well.
It’s often said that a garage conversion can take anywhere between 1 week to 1 month, depending on the size and scope. But many standard conversions without any plumbing can take as little as 5 days. Your contractor will be able to tell you exactly how long your garage conversion will take.
Are you considering converting your garage into a more usable space in your home? If yes, then you’d probably want to know if you’ll require building regs before converting the garage. The answer to this question is yes. Although you may not require planning approval to convert your garage into a more usable space, but you’d usually need approval under the Building Regulations.
When re-structuring your garage into a habitable space, the following should be taken into consideration: structural alterations, ventilation, moisture proofing, insulation, fireproofing, escape routes as well as the submission of a building building notice or full plan application to the local council in order to inform them about the planned project.
• Walls
You’ll require an approval if you plan to infill the garage door with a window and a new wall. This is because the garage may have been built of a shallow slab which implies that a new foundation would be needed for the new wall construction.
• Floor
Even though there’s a high possibility that the garage floor is strong enough for domestic use since its designed to withstand the weight of vehicles, you may however need to upgrade to make sure it suitable for both thermal insulation and damp proofing. In addition, there may also be the need to to alter the floor level in such a way that it matches that of the remaining parts of the house.
• Ventilation
According to the Building Regulations requirements, there’s a need for adequate ventilation for each individual rooms which includes garage conversions for general health purposes. What’s going to determine the ventilation level that’ll be required is the frequency at which the room is used. Ventilation can be provided through purge or simply opening the window or via trickle ventilation.
