A house in Marrickville had a timber security side gate to stop access down the side of the house. Being timber it was also impossible to see down the side of the house or see someone who may be wanting to get past the gate.
The owner decided she wanted a steel security gate made that had a similar design to the existing front gate of the property. It would also allow her to see who may be wanting to enter down the side of the house.
A dead lock was needed to fit into the steel support rails so the gate could not be opened without the key.

The existing gate (shown on the left) was used as a basis to develop the full height door design as shown above.
Fitting the dead lock to the steel SHS tubing required inserting 12mm steel plates into the 1.6mm walls of the steel tube so threaded holes could be cut to secure the lock catch attaching screws.

A recent project involved the design of Art Deco folding security panels to secure the alcoholic assets of a CBD Sydney bar. The Reagh Bar at the Castlereagh Boutique Hotel needed to leave their bar stock on the shelves behind the bar rather than having to put it all away each night and re-stock the following evening.
The Art Deco era Castlereagh Hotel opened on September 12th, 1927 and was built by the New South Wales Masonic Club. It was the first reinforced concrete building in the Sydney CBD and, at the time, was the tallest building in Sydney with 12 floors. Its construction set the precedent for future CBD buildings. It has been the base for the Masonic Club ever since and they wanted something sympathetic to the Art Deco era of the hotel for the folding security panel design.
Our PLAZA style Art Deco design was selected as the optimum style for the folding panels. The design brief was for security panels that could be easily locked and opened and not be too obtrusive. A set of six centre opening Art Deco style panels were designed that satisfied the brief while keeping the overall look light and airy. Clear polycarbonate panels were attached to the back of the folding panels to prevent access to the the bottle stock through the steel bars when the panels were locked closed.
The following photos illustrate the construction of the folding panels. To keep the visual impact of the bars to a minimum 20mm wide framing was chosen. To avoid having two adjacent 20mm vertical bars together making 40mm wide vertical sections 20x10mm solid steel verticals were used which presented a combined 20mm width overall. This made attaching the clear polycarbonate back panels difficult. Since each panel required forty screws to attach to the frames they had to be individually drilled and tapped into the solid 20x10mm sections to accommodate the fastening screws.
The geometry of the six folding panels was crucial and they had to be millimetre perfect so they would meet in the middle of the bar section and lock together.
The top and bottom sections of the frames were hollow 20x20mm SHS steel and only 1.6mm thick so 12mm thick sections had to be fitted into them so the pivots had something solid to screw into.

To keep the overall look light and airy the clear panels needed to screw directly to the back of the 10mm wide vertical bar sections. This required drilling and threading for 240 screws. To simplify construction the panel operation geometry was done before the design was welded into them.

Once the panel folding geometry had been confirmed the PLAZA design was jigged into place in the frames and welded in position.

The clear polycarbonate panels were attached after all the welding was completed. To accurately drill the screw holes in the panels dummy screws with sharpened heads were fitted into the screw positions and the polycarbonate was hit lightly with a hammer over each screw point to indicate where the holes should be drilled. Preliminary testing of the panel operation is shown in the video below.

The folding panels are supported and slide inside tracking sections at the top and bottom. The bottom tracking can be removed when the panels are stowed open on each side. When closed the panels are secured together with a pivoting drop bolt. The operation of the panels is shown in the video at the end of the post.
A client wanted custom side gates built for their Art Deco home that would match the style of the original front gates on their property.
The side of the house where the side gates were required was a little wider than normal which would make a single gate too large. Centre opening double side gates were suggested which would have a more pleasing aesthetic. The fence on the side of the house was too flimsy to support a gate so a 100mm square steel pillar needed to be installed to support one side.
Using the original front gates (which we had just restored) as a guide, a suitable design for the side gates was developed which captured the look we were after.

The installation was very straight forward but the house was cement rendered and there was no way of knowing if you were drilling into bricks or mortar so dynabolts would be a bit dicey. Instead it was decided to use Chemset studs which provided a much more secure anchor without putting undue stress on the brickwork.
The installation of the custom side gates has made a nice addition to the overall look of the property.
Many older style homes and units have outward opening bathroom windows which makes it difficult to install suitable security bars. The solution we offered a client was to install them on the inside of the bathroom windows.
Interior security bar installations present their own set of difficulties not least of which is being able to open and close the windows which are now behind the bars.
These particular windows have a long arm which needed to be able to swing up from the locked position and then pivot out to push the window open. This was achieved by using a cross motif in the design which allows the opening arm to be manipulated through the open areas of the bars.
A client wanted some Art Deco style removable security bars for her bathroom windows. Because it was a block of flats she wanted the removable bars mounted on the inside of the windows so that the outside appearance of the building wasn’t affected.
The security bars use a simple ODEON Art Deco design which is mirrored in the opposite window to achieve a more balanced look.
The removable bars are held in position by brackets fixed into the bottom of the window frames and locked in position by two standard window locks attached to the top section of the security bar frames. The bars can be removed by removing the two pins in the locks and pivoting them forward and out of the bottom brackets.
The pictures below illustrate how the removable bars are fitted/removed.

These ODEON style Art Deco security doors make an attractive additional to this turn of the century Sydney Semi.
The double doors stand three metres tall and mirror the arched entry to the verandah. The high centre opening doors create an impressive and expansive entrance to the house.
The top and bottom drop bolts used to secure the left hand side door have been fitted inside the door frame and operate in a similar manner to a rifle bolt with the operate knobs fitted near the centre of the door. With the right hand side door locked the drop bolts are also locked as they can only operate with the right hand door open.
The all steel framework is painted a metallic grey and fitted with plain dead lock. The ODEON is one of several designs unique to DecoWorks.

This Plaza style Art Deco front gate makes a stylish entrance into the new front courtyard of this terrace house.
In collaboration with the client the standard Plaza design was adjusted to suit the new front courtyard wall which replaced the old fence of the terrace house.
The addition of the garden bed along the front of the wall helps create an attractive overall design to the new wall.
