Garage conversion FAQs

How long does a garage conversion take?

Garage conversion is a great way to add extra usable space to your home without having to extend your property. A fun fact is that, in the UK if you have your car parked in the garage, you’re in the minority. According to a research carried out by Admiral Loans, just about 33 percent of home owners in the UK store their cars in the garage. For most people the garage is literally a dumping ground that’s never fully utilized as such. In recent times, the garage is now being used to store a variety of other stuffs asides a car which includes garden furniture, tools and appliances, utilities such as washing machine, fridge and freezer as well as food and groceries. These facts show that more and more people are underutilizing their garage when they may actually be in need of more usable space in their property. So why not put into consideration converting the garage into a new space that would be able to serve more purpose?

If you’ve decided to convert your garage, you’d probably want to know the how long the project will take. There are a wide range of factors that can determine the duration of a garage conversion project. These factors include:

• If the foundation needs reinforcing

• If the floors, walls, or roofs are in a bad condition.

• If the ceiling height needs some raising

• If the insulation required in newer builds.

All aforementioned factors will make the garage conversion project take longer than expected. However, in normal situations garage conversions are relatively quick to complete once you start the building works. A single-car conversion will usually take about 3 to 4 weeks to complete depending on the existing garage’s structure.

Do I need planning permission for a garage conversion?

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.

Will the company deal with the building control application?

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.

How long will my garage conversion take?

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.

What is a garage conversion?

What is your garage being used for? If your answer is anything besides your vehicle, you’re in the majority in the UK. In the country, according to a research by Admiralty Loans, several home and property owners now use their garage as dumping ground for all sorts of stuffs asides a car. Ultimately, this gives rise to garage conversions as the more or less underutilized space can be converted into a living space which can be more beneficial while also adding more value to the property.

A garage conversion is a fast and relatively affordable route to adding more floor space within your home. It’s basically the act of changing your garage into something other than a storage or a place in which you can park your car. This can be anything from a bedroom to a playroom and anything in between. It’s a great way to provide extra space to allow your family to spread out and have more privacy while still within the walls of your home.

A garage conversion project is a huge one which mostly does not require a planning application so far the conversion is internal. However if you’re planning to increase the garage’s size or change the exterior of your home, or convert your garage into a separate room, then you may require a planning permission before getting started. It’s always wise to consult your local authority before carrying out any work to be on the safer side.

A project of garage conversion’s magnitude is better left to a reliable professional who have the experience when it comes to dealing with building regulations and more. This way, you’d also get to save yourself some headaches and some extra cash which may result from possible costly errors.

Will my garage conversion cause disruption to the rest of the house?

It shouldn’t do. Most companies will do all the interior work first, and the last job to do will be creating the opening from the house to the conversion. A reputable company will make sure they cause as little disruption as possible during this time.

How much does a garage conversion cost?

Are you looking to create some more space in your home with your garage being almost dispensable? If yes, then considering a garage conversion project may be the way to go. Unlike many other extension options, garage conversion does not take up an additional space as it only changes the current structure of the garage. As a result, the cost of completing a garage conversion project can be relatively attractive when compared to other space creating alternatives. So exactly how much would a garage conversion project cost? Well, there’s no precise answer for this as several influencing factors come to play. However, in this guide we’ll give you a rough idea of the average costs that you’re likely going to encounter. Some of the factors that can influence your budget dramatically includes the following:

• The size of the conversion. The larger the size of the garage per square feet, the more cost you’ll have to expend.

• The type of your property - listed buildings are usually more expensive.

• Your location in the UK. If you stay in London where there’s a higher demand, you’ll most likely pay more.

• You’re likely to pay more if a specialist knowledge is required.

• The amount of glazing to be installed

• Quality of the materials to be incorporated.

• Quality of the professional to carry out the installation service.

On average, when it comes to garage conversion projects, you’re likely to pay the following depending on the per square metre given:

• A single garage of about 15 square metre will cost within the range of £6,000 to £15,000.

• A double garage of about 30 square metre will cost within the range of £12,000 to £30,000.

Do you need an architect for a garage conversion?
Have you decided to convert that under-utilized space ( garage) in your home to a more habitable space where you can do anything asides general storage or parking a car? If yes, then you’d probably want to know where to start or if you’d require an architect to get started. Well, you’re not alone! This is one of the most frequently asked questions when it comes to garage conversions and reasonably so. Talking about where to get started, when it comes to home improvement projects the first step to take is determining whether or not you’d require a planning permission or if your proposed garage conversion is covered under permitted development rights. Once you’ve been able to conclude on that, the next step is deciding whether you’re going to complete the project yourself, hire the services of tradesmen or employing a builder. And this ultimately brings us to the question of whether you’ll need an architect for a garage conversion. To get started, it’s highly recommended that you employ the services of a professional architect or an architectural technologist to assist in designing your garage conversion. However, most garage conversion projects are straightforward with no complex changes to be made so far you wish to avoid applying for a planning permission and staying within the set guidelines of the permitted development rights. In such events, if you’re properly trained and well experienced in the field, then it may be cost effective to design your garage conversion by yourself. It should, however, be noted that it all depends on your personal preferences and budget. If you’re on tight budget and don’t mind a straightforward design, you can save cost by not hiring an architect.
