For those who have an unused garage area, why not consider a conversion in Lisburn to make the most from your home. Compare up to four free quotes with our service to get the ideal price for a conversion.
One of the leading advantages with a garage conversion is the space can be transformed quickly for the additional room you will need, whether or not it's for a growing family or just to add to the price of your house.
A garage conversion means you won't need to relocate for extra space, which could help you save thousands of pounds on solicitor costs, estate agent payments and stamp duty. And the extra space can be transformed into what you need, whether it's an expansion to the living area or kitchen, or a separate room completely.
With the infrastructure already in position it's clear that a garage conversion will probably be cheaper than creating an extension too, and won't eat valuable space in your garden. With the exterior unlikely to change too, it's a good way to bypass restrictions for conservation areas and listed buildings.

Most companies will make the building control application on your behalf and ensure that all the work is completed to the right standards. When a building inspector has inspected it, you’ll get a certificate. It usually takes around 6-8 weeks after completion to come.
Are you thinking about converting your garage into a new space? Be it a new bedroom, gym, library or playroom, one thing you’ll have to consider before getting started is whether or not you’re going to require a planning permission. Unlike extensions that needs additional space, garage conversion is all about changing the existing structure of a space that’s already available to you - your garage. As a result, these projects are mostly covered by a planning policy that’s a bit different.
For a garage conversion, it’s very unlikely that you’ll need a planning permission. As a matter of fact, only 10 percent of garage conversions has been estimated to need a full planning permission, with the others coming under the permitted development rights. The permitted development rights, however, only provides coverage for home improvements that’s internal which implies that so far you’re not trying to enlarge your garage, you’ll not require a planning permission. But if otherwise, you’ll have to submit an application before commencing your project.
If you’re looking to comply with the permitted development rights, then your project must comply with some specific guidelines. These rules include the following:
• The work should be internal. No plans to enlarge or extend the existing garage.
• You should make sure that the materials used in carrying out the garage conversion is the same with the materials used in building the existing house.
• The building should not be extended.
You may, however, require a planning permission if you’re going to change a detached garage into a living space which could be a bedroom, small annexe or a living room.
Some houses excluded from the permitted development rights include flats, listed buildings, some new developments and most homes in a conservation area.
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.
