Our thoughts

This is a great piece of kit. It has a good range and is very reliable. The motor is very powerful, capable of pulling the heaviest of lenses and yet extremely quiet.

We are open for business but have altered the way we work to maintain a safe working environment. As a small but resilient company and we are always happy to tailor our services to your specific requirements.

Studio 2 is now available for full 10-hour day hire only and comes with the the extra room above it as standard to accommodate extra crew numbers. Contact us for more details.

Our studios have fresh air ventilation systems which provide a constant supply of fresh air as opposed to a recirculation system. They are also quiet enough to run whilst recording sound

We have just installed a dual internet system that runs on fast 5G in addition to fibre broadband so that we can offer a very robust internet connection for live video streaming etc.

We can provide a reliable online video stream from the studios so that your client can monitor the shoot remotely

There is remote audio and video monitoring provided from the studio to the client room and both dressing rooms for Studio 1 and to the client room for Studio 2. Studio 1 also have a microphone set up in the green room so that you can communicate remotely via the PA

We have opened a roof garden in addition to the private yard so we can offer clients more outdoor ancillary space
