Forming part of the Carmelite Monastery, the original section of the Roman Catholic Archbishops residence was built by Adelaide architect Albert Conrad in the early 1900’s. The residence was designed in a ‘modern domestic gothic style of architecture’. It remains listed as a state heritage building.

HSR are currently undertaking the conservation and restoration of the Carmelite Archbishops residence.

The scope of works include:

• Specialist masonry facade cleaning using the Doff system and Biocide treatment
• Demolition of non-original buildings and fabrics
• Stonework repair and conservation works
• Repointing
• Tower and Chimney works including strengthening
• Construction of new brick quoins
• Heritage roofing
• Salt damp injections
• Repairs to salvaged crosses
• Reinstating original stone and brick features

Trinity Church was first built in 1845 and extended in 1888-9, when it was transformed to its existing Victorian Gothic style.
Pointed windows were installed, a pitched roof with fine timber trusses and the tower was extended to its present height. Twentieth century additions include galleries, the organ loft, and extra vestry space.

HSR carried out conservation works to the North elevation and tower.

The scope of works included:

• Repointing
• Specialist facade cleaning
• Stone conservation
• Carpentry repairs
• Solid rendering to tower
• Heritage painting to all render features and timber

HSR were engaged by Renewal SA to carry out a full dilapidation and associated costs to the East/South and Western facades of the Adelaide Railway station in order to determine a scope of works for the repair of structural and non-structural rendered elements that form the facades of the Railway Station.

Prior to the works being carried out the façade was cleaned by HSR using a steam pressure cleaner which provides a super-heated steam rather than the usual high-water pressure, this machine removes all dirt /grime etc. without the risk of excessive water penetration into the open cracks etc.

Various repair methods were used on the project as outlined below:

• Full render repair – Removal of a defective area and replace with new render that matches exactly with the original in both colour and texture.
• Crack injection- small cracks are filled with a coloured mortar to match existing, then a two-part epoxy resin is carefully injected into the crack using small syringes.
• Structural repairs- in the case of steel corrosion behind the render, the render is removed to expose the underlying steel reinforcing which is then cleaned to remove loose corrosion, once cleaned the steel is treated with a zinc rich protective coating, then treated the area is re rendered to match the existing.
• Protective membrane application – a protective coating was applied to all horizontal surfaces Window sills /cornice sections etc. in order to provide a stable waterproof finish.
• Entire replacement of moulded sections under the cornice – In some cases continuous water penetration had caused severe corrosion of the Modillions which form a decorative part on the underside of the cornice, due to their friable nature these sections had to be removed entirely and new pieces carved by HSR masons and fixed into place.

Extensive works reinstating all damaged heritage brickwork, ornate solid rendering to external facades including all internal rendering and plastering, and making good cornices and mouldings.

New and refurbished metal windows and guarding, and specialist cleaning to all masonry facades.

The project included the conservation and restoration works to the exterior and interior of the telecommunications exchange building.

The scope of works involved specialist façade cleaning, heritage brick work, stone and timber conservation and solid rendering.

HSR were engaged by the main contractor Complete Building Services to carry out a full dismantle and rebuild of the entire Northern elevation of the Maid and Magpie Hotel in order to rectify the damage created by the subsidence within the original footings.

Full dilapidation was carried out by HSR prior to commencement of the project which included a comprehensive photographic record and exact dimensions of each element of the area, this included locations of windows, chimneys and any other feature that needed to be re-instated during the rebuilding process.

Starting at the roof line of the elevation the entire North wall was carefully dismantled brick by brick and stone by stone with each individual item being documented and cleaned for re use.

Over a period of several weeks the process continued until the entire wall was taken down and catalogued by a team of HSR masons, with all bricks and stone carefully palletised according to its location thus ensuring the materials were re laid in their original position.

Once a new concrete footing was installed HSR began the process of rebuilding the elevation using all the previously salvaged original materials and utilising the details taken during the dismantling process.

Consultation with the project Architect and Heritage advisor ensured that the rebuilding process produced an exact re instatement of the original Northern Elevation in every detail.

HSR undertook conservation works to 302 North Terrace, a state heritage building. The areas of work included north external façade, front fence and interior.

The scope included:

• Specialist facade cleaning to stonework and render.
• Timber repairs works to windows
• Stone replacement and repointing
• Repairs to render and cast iron
• Timber replacement
• Internal cornice, ceiling and plaster repair
• Timber flooring works
• Slate steps replacement
• External heritage painting

St Peters college was founded in 1847 and is a school rich with history and tradition.

Extensive stone conservation works were undertaken by HSR to the college and drinking fountain, the scope included:

• Specialist Facade Cleaning
• Stonework repairs
• Stone repointing using traditional lime mortar
• Crack repairs to drinking fountain
