Key Details

  • Garage Conversion

    Whats your Garage used for?
    Only 20% of home garages are used to store cars.
    The majority of home garages become storage space, or in effect expensive garden sheds.
    Modern garages, as a rule, are not big enough to allow the doors to be opened on the average sized, modern family car.
    Why Not convert the garage space into a usable living space for you or your family to enjoy

  • Garage Makeover

    Many people are looking at garage renovation as an extension of their home,
    and coming up with ways to turn it into a viable living area.
    You can convert part or all of your garage into an entertainment room,
    an extra bedroom, a family room or an indoor/outdoor dining area,
    or just about anything else you can come up with

  • Garage Renovation

    We specialise in garage refurbishment and transformation.
    This can be from fitting a new roof to a full strip down of an existing garage and refit.
    We have a number of options available to suit all kinds of tastes and budgets.
    We have been performing garage renovations for over 10 years so you can rely on our expertise.

  • Structural Work

    When we’re creating garage conversions, our first step is to remove the garage door. We can fill in this gap with brick, windows or doors, and we can match their colour and style to what you already have in your property.
    This means your garage conversion will fit in seamlessly – your guests will never guess that it used to be a garage.
    We usually insulate the new wall with 100mm Celotex to reduce heat loss.

  • Insulated Flooring

    Most garages have a solid concrete base to support a heavy car.
    This concrete slab gets very cold in winter, so we usually install a special 20mm thick insulated flooring.
    Less than an inch thick, this flooring maximises headroom.
    Garages often have low-hanging ceilings, so this is vital for converting it into a functional room.
    If you need your garage conversion to be in level with the rest of your property, we can install thicker flooring so that the two match up.

  • Finishing the Walls

    We’ve already insulated the front wall of your garage conversion, so we add a solid slab of insulation straight onto the other three walls to make the whole room retain heat more effectively.
    The insulation boards can then be plastered over and painted or wallpapered.
    We can then finish off your new garage conversion with all the fixings and fittings you need, and we can even heating and electrics – it’s all part of the service.

  • 10 Year Guarantees

    All of our garage conversions come with an insurance backed 10 year guarantee to deliver a total peace of mind solution.

  • Free Survey and Design Consultation

    bedroom with or without en-suite facilities.
