Site Survey

Your onsite design consultant will visit you in your home and talk to you about your plans. Your consultant will help finalise your design, answer any additional questions you may have and finalise your quote. They’ll also give advice on location, site clearance and check the sites access and parking. We’ll check the location of your electrics and water/waste and talk you through how we will connect the utilities. At the end of your survey we’ll give you a full quotation.

Ordering Process

Once you’re happy with the design of your garden annex, we can get you booked into our schedule. We build between 20 and 25 buildings a week, which gives us plenty of flexibility to find a date to suit you. Once you’ve paid your initial deposit we’ll start the planning process immediately. This usually takes around 12 weeks.

    Planning Permission

    Anyone can apply for planning permission, but not everyone will get the same results. That’s why we use a specialist planning consultant. With over a decade’s experience in annex planning, our planning consultant will submit your plans, liaise with your planning officer and give you updates along the way.

    Our planning consultant will amalgamate the information from your site survey, local planning policies and your building design. Householder planning applications are judged on a case by case basis, taking individual circumstances into account. Our consultant will also help you write a supporting statement to submit along with the application.

  • Your customer care advisor

    Your customer care advisor is with you all the way. A one person contact throughout the process to give you all the information you need. They’ll liaise with you on all your dates, answer any questions and provide you one contact point throughout.

  • Base preparation, foundations & plumbing services

    Our base team will come on day one and start work on your annex. The team will dig the holes for your foundations and trenches for your plumbing. On day two our building control inspector will visit to sign off the depth of the foundations. The base team return on day three to lay pipes, install the foundations and install the floor panels in place.

  • Installing your annex

    The main build team arrive the following week and the annex starts to really take shape. Walls and roof are installed in a day, and doors and windows follow shortly after. The internal stud work is completed shortly after and first fix electrics commence before plaster boarding of your garden annex. Our plastering team will skim the building, which is left to dry before the decorating team come in and paint. Our bathroom and kitchen installers are next, followed by the final fix electricians and finally the build team again. They’ll finish off your decking, install the flooring and skirting. This process takes anywhere from 3 – 5 weeks depending on the size of the annex and drying times.

  • Building control inspection and handing you the keys

    Our building control inspector will return and check the building over. They’ll check the connection of services, collect the electricians sign off paperwork and issue a building control certificate. We can then give you a full tour or your building, explain how everything works and hand over the keys.

  • Your guarantee

    Once the building is installed we’re still here to help. We have 15 install teams all over the country on any given day, so in the unlikely event you do have any problems, we won’t be far away.

  • Payment schedule

    A £2500 non-refundabledeposit will secure your installation date, cover a technical survey and start the planning permission process. An initial ground screw test is carried out, and if this should fail and there are no alternatives available for the ground of your project you will be refunded £2000 of your deposit.
    After planning permission is granted we ask for a 60% (less the initial £2500 already paid) 6 weeks before installation of your building. At this point the building is put into production and your doors, windows, bathroom and kitchen are ordered. We then require a further 30% payment on completion of your groundworks and the remaining 10% on sign off of your finished building.

    Our initial deposit covers the cost of our planning consultant and in house CAD drawings so unfortunately we are unable to refund the initial deposit if planning permission is declined.
