Garage transformation specialists in Brentwood

If you have an rarely used garage area, why not look at a conversion within Brentwood to make the most from your property. Contrast as many as four totally free quotations with our service and get the top price for a conversion.

One of the leading benefits with a garage conversion would be that the space can be transformed quickly for the additional room you'll need, whether or not it's for a growing family or just to add to the value of your property.

A garage conversion suggests you won't have to relocate for extra space, which may help you save a lot of money on solicitor costs, estate agent payments and stamp duty. And the extra room can be changed into whatever you need, whether it's an extension to the living area or kitchen, or a separate room entirely.

With the structure already in position it's evident that a garage conversion is going to be less expensive than constructing an extension also, and won't consume valuable space within your garden. With the outside not likely to change too, it's an alternative way to get around rules for conservation areas and also listed buildings.

Should you be serious about converting your garage, check quotes from companies within Brentwood using our easy and quick service to get the very best deal available.

FAQs

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.

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 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.

Will I need planning permission or building regulations approval?

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.
