  • Garage Conversion Types
    A garage conversion can be the ideal solution if you require more living space. When a conversion is done correctly, it can be a very cost-effective and practical way to convert unused space into an additional room. However, before you commence with your conversion plans, you will need to identify the kind of garage that you have i.e. single, detached, double, tandem etc. and assess its suitability for conversion.


    Single Garage Conversion

    A standard-sized single garage can add approximately 150 square feet of additional floor space to your home. Single garages are ideal for small rooms such as bathrooms, playrooms, home offices, utility rooms and single bedrooms. If your garage is attached to the house, it can also be used as an extension to another room i.e. the kitchen.


    Double Garage Conversion

    If you have a double garage, you have the option to convert the entire space, or a partial area, leaving room for storage or keeping half as a traditional garage. If you decide to convert the whole space you can expect to add around 300 square feet to your home with a double garage conversion.


    Tandem Garage Conversion

    As per a double garage, a tandem garage provides you with the option to convert the entire space, or a partial area. Many people prefer to retain a section of the garage for the storage of tools and larger objects i.e. lawnmowers and exercise equipment. You may also have white goods in there – appliances like tumble dryers, freezers and fridges are commonplace.


    Detached Garage Conversion

    If you have a detached garage, you will need to check any applicable legalities before you commence with any work. For example; you may need to make an application for planning permission to change its intended usage.

  • Design & Planning

    The team at Create-Room can originate full working drawings and structural calculations for your proposed garage conversion.

    We will demonstrate our experience when preparing your plans. They will be originated to provide you the maximum space achievable while being considerate to the existing property. We will consider all relevant approvals required so that they are considered in the design of your garage conversion.

    Garage design is specialised and many draughtsman do not consider ambiguous elements such as creating adequate head height, when converting your garage. We have the experience so that we consider all factors.

    We have numerous garages that we have previously converted for you to look at. This may help when deciding on a final design for your garage conversion.


    An appointment will be made and one of our experienced Surveyors will visit your property. Accurate measurements & dimensions of the existing dwelling are recorded and photographic evidence of your existing property will be taken.

    This will enable us to be sympathetic with the existing property when designing your proposed conversion. Preliminary drawings will then be originated in accordance with your specific requirements.


    The preliminary drawings will be presented to you for your approval. Any amendments in the design or layout can be made at this point.

    Once you are happy with the plans, Full working plans will be originated incorporating a structural layout. Full, working structural calculations will be originated.

  • Building Regulations

    If you are considering a garage conversion you will need to find out if planning permission is required for any of the work that you intend to carry out on the building. Many people assume that planning permission is required as standard for all garage conversions – however, only around 10% of all garage conversions will require local authority planning permission. To this end, it’s important to check with your local authority before you commence with any garage building or conversion work.

    Planning permission rules have changed somewhat in recent years. New regulations came into effect on 1 October 2008 specifying that the majority of garage conversions do not require planning permission, providing that the work is internal and that the conversion does not involve making the garage any larger in size. Generally speaking, the majority of properties will have permitted development rights allowing for certain types of work.

    Permitted development is a categorisation of any work that can be performed without the need to obtain planning permission first. The majority of garage conversions will automatically fall into this category. However, some properties may have had their permitted development rights removed at the time of their original build. In these cases, planning permission will need to be applied for prior to a garage conversion.

    If you are planning a garage conversion project and you are not sure about planning permission, if it is required for your project, or what it means, you will need to contact your local authority for more advice. Naturally, planning permission rules will differ depending on a number of factors, including the type of garage that you own, its location (i.e. if it is attached to your home or it is an independent structure) and the work that you are intending to carry out on it (i.e. the intended purpose for the space).

    It is very important to check if planning permission is required before you commence with any conversion work on your garage. If you fail to do this, and find out at a later date that planning permission was required – you may be required by law to reverse any work that you have already completed. This must be done at your own cost so it can obviously be a very expensive and time-consuming task. Your local authority should be able to answer any questions that you have about planning permission in relation to your conversion.

    Prior to starting the project, we will also need to check any building regulations that apply to your conversion and how we must adhere to them.

  • Construction Overview


    A dedicated garage Conversions team will be assigned to your project. A Principal Contractor will be responsible for the whole of your garage Conversion, from start to finish. This will be the person you can liaise with on a daily basis and will coordinate the various trades and suppliers needed to convert your loft.

    During your garage Conversion, our Project Manager will visit you. They will ensure that work is progressing in accordance with the work schedule and address any concerns or questions you may have.

    Our team will certify each of your stage payment, ensuring that you are paying for the work completed on site.

    The Building Control Inspector will also be attending the site periodically throughout the build. They will ensure that all aspects of the work are being carried out in accordance with current Building Control Regulations.

    No two garage conversions will never be the same. Deviating factors will determine the precise way your garage is converted.

  • Stages Of Work

    Stage 1: Electrical & Pluming First Fix

    Our NICEIC Registered Electrical Contractor carries out the electrical first fix, in this example we:

    – remove the ceiling completely to facilitate the works
    – wire for 6nr fire rated downlight
    – wire for 3nr double sockets
    – wire 1nr BT point

    Relocate existing alarm base station, keypad and sensor

    Relocate sockets and light switches to make way for new door opening

    Relocate consumer unit to high level and ensure that meter tails are adequately protected

    Our Corgi Registered Plumbing Contractor carries out the plumbing first fix, in this example we:

    – Remove radiator and pipework from hallway to facilitate new door opening
    – Provide 1st fix pipework to new radiatior position in the proposed garage conversion.
    – Re-route boiler condense pipework
    – Re-route the emergency blow off pipework from the pressurised hot water cylinder

    Stage 2: Form Structural Opening & Brickwork

    In this example the front elevation of the property is carried by a catnic lintol that bears over the proposed internal door opening. With this in mind and after consulting with our advising structural engineer we install 2nr catnic heavy duty steel lintols to carry the additional loadings imposed.

    The existing floor slab is cut out to provide a visual inspection to ascertain the suitability of the existing foundation to carry the new loads imposed by the brickwork, blockwork and window frame. Once inspected, the brickwork to the garage reveals are “toothed” out in preparation for the new brickwork & blockwork.

    The cavity is fully insulated with Rockwool cavity batts.

    Dual cavity trays are inserted to ensure that any penetrating water will be dispersed back through the front brickwork via the newly inserted “weep vents”, One of these cavity trays is also linked in with the newly inserted floor DPM.

    Works to date are inspected by the building inspector.

    Stage 3: Raising The Floor

    Where the difference in level between the house and garage permits, insulation is laid onto the existing floor, a Damp proof membrane is installed – linking in with external cavity trays.

    In this example (our preferred method) the floor is then overlaid with a fibre reinforced cement screed. Alternate timber methods are available, but as most ground floors are concrete it is our opinion that the new floor should “feel” the same underfoot from one room to the next– a screeded floor is not susceptible to squeeks or creeks.

    Stage 4: Window, Insulation & Plasterwork

    The window is fitted complete with trickle ventilation to provide background room ventilation. In some cases (where the garage exits onto a room rather than a hallway ) fire escape hinges would be fitted to allow escape in the event of a fire.

    In this example part of the garage ceiling was covered by a sloping tiled roof, this area was insulated with 300mm of rockwool loft insulation to provide ventilation to the subsequent “Cold Roof” void, cross ventilation was provided at soffit and ridge level to avoid a build up of condensation.

    25mm kingspan insulation is provided to window reveals to avoid “cold bridging” between the external and internal reveals.

    Depending upon the existing construction, insulation is provided to the external walls prior to plasterwork.

    Where there is a existing room above the garage, insulation is provided between the floor joists to prevent the passage of sound.

    Walls and ceilings are plaster boarded with 12.5mm plasterboard and skimmed.

    Stage 5: Electrical & Plumbing Second Fixes

    The electrical contractor carries out the installation of ceiling lights, sockets and switches – note the use of lazer alignment when fixing spotlights. Upon completion a test certificate is supplied for the homeowner.

    The radiator – complete with thermostatic control valve is connected to the existing system and a check / balance of the existing heating system takes place.

    Stage 6: Joinery

    – New skirtings & architraves are fitted.
    – Cupboards are constructed and fitted.
    – New door, handle etc is fitted to match the existing home.
    – In this example we supply and install uniclic perspective flooring.

    Stage 7: Pre-Completion Inspection

    – All remaining rubbish / surplus material is removed.
    – The new and surrounding brickwork is acid cleaned.
    – An internal and external inspection is carried out.
    – Warranties, certificates etc are issued.
    – Building inspector carries out a final inspection and issues compliance certificate to homeowner directly.
    – After the conversion completion, the homeowner carries out the decoration, however are happy to decorate your garage conversion should you require it.
