The owners of a new property in Middlesex wanted an electric gate system to increase security of their open driveway whilst giving the entrance an identity. To maximise car parking and turning space, a swing gate was not a viable option, a cantilevered sliding gate therefore being the ideal solution. The owners of the property designed the house themselves and wanted a contemporary design for the gate – one that would replicate the new garage door ensuring harmonisation of the entrance with the house.
Renzland Powergates Ltd consulted with the client, designed and managed the entire project from initial visualisation, CAD approval drawings, installation, handover, completion and ongoing maintenance via our warranty. Whilst it was possible to replicate the existing garage door using timber, the client did not want the ongoing maintenance associated with wooden gates. It was therefore decided to produce the sliding gate from garage door panels to match what was existing. With the garage door having been manufactured by Hormann, Renzland liaised with Hormann in Germany and had a custom size garage door made based on CAD drawings we produced, and which had been approved by the client. Producing CAD drawings eliminated any misunderstandings and provided the basis of the working technical drawings with which to complete the project. The garage panel required was over 4 meters long and one of the largest single sectional garage doors Hormann had ever produced. It was very important that aesthetically the gate looked beautiful from both sides. As the garage door panels from Hormann are white on one side, it was decided that we would place 2 panels back to back so that the wood grain was visible from both sides, after all, the rear (inside) was the elevation the clients would spend most of their time looking at! The system required custom framework inside to hold everything together, which was then galvanised and powder coated in black. The framework was designed so that the garage door panels all dovetailed together and no fixings were therefore visible from the outside. The framework and panels were test fit at our workshop and assembled on site to ensure the cantilevered sliding gate installation was straight forward and as little time as possible was spent at the clients home, thus minimising disruption. A cantilever sliding gate was chosen over its track based counterpart due to the following reasons- 1) This was a quiet residential road and a cantilever sliding gate compared with a tracked gate system is almost silent in operation. 2) The shingle driveway could cause potential problems with a tracked system due to stone blockage. Cantilever gates are more complex in installation with precise sub surface metal fabrication required. A cantilevered sliding gate is 30% larger than a swing gate in order to accommodate the counterbalance, are technically more difficult to install, and in our professional opinion, require a higher level of skill. Indeed during this installation our engineers accidentally struck a water main which did not show up on the CAT scan, this quickly being repaired without any delay or disruption to the installation. BFT anti crush 24v motors were chosen due to their reliability and engineering quality. Finally after the gates were fitted, the access control (intercom) was installed. A wireless access control system in itself proved more challenging than normal due to the new house having been made of ICF Construction – Insulated Concrete Formwork. With all the benefits that come with an ICF house, the one disadvantage is that it suppresses signals, due to the concrete walls and thick insulation. Our suggested access control system however was tested at site prior to installation, and proved to be more than up to the task. The handsets were also tested as far as the back of the clients large garden, and again proved suitable for the job. The post box was relocated as both the client and ourselves preferred a separate post box rather than an integral post box in the gate itself. As a finishing touch we fitted a bespoke welsh slate house sign, hand finished with silver patina.
The client received a truly one of a kind bespoke cantilevered sliding gate, that met their design brief. Due to the heavy duty internal framework and cantilevered system, it is an impressive and substantial piece of custom engineered art which slides effortlessly and adds value to the home, whilst also keeping the family safe and secure for many years to come.

David & his first class team managed to produce exactly what we envisioned so that we ended up with a truly bespoke and beautiful gate. They met the technical and aesthetic challenges with aplomb. Highly recommended.
