Lazenby

Cannon Green’s RC cast in situ polished concrete staircase is an Ocubis project in conjunction with John Robertson Architects (JRA), Civic Engineers and Six Smith Build. Lazenby built and installed the 21m long, 7m high and 7.5m wide (at the top) inverted amphitheater cast in situ Pewter concrete staircase. This staircase was designed by JRA and structurally engineered by Civic Engineers, incorporating BIM modelling due of the intricacies of the reinforcement design. This self-supporting staircase is tied into the structure with a steel stringer to convert the loads and moments down through the steel columns.Lazenby installed traditional formwork to create the stepped soffit that leads up to the inverted amphitheatre steps. Lazenby then installed a false work system (from Ischebeck Titan/Inform UK) enabling the formworkers to create the radius former inverted amphitheatre undercarriage that is visible from the restaurant (Drake & Morgan). The reinforcement was then added to the soffit and steps; the carpenters then added formers and attached nearly 700 DDA studs to the formwork prior to the casting of concrete.Lazenby’s integral-coloured Pewter polished concrete was batched on site into a C32/40 concrete supplied by London Concrete. The project used approx. 24 cubic meters of concrete and 6 tonnes of steel reinforcement. Ground floor to the top landing and seating area is just over 4m high, 21m long and 7.5m wide with 24 shallow risers and 3 functional landings. The first 3m wide step widens to a 7.5m inverted amphitheatre style landing featuring single and double height steps.Lazenby’s 8 master craftsmen were onsite for the duration of this 12-week project. Lazenby won the Cannon Green project based on the ability to deliver unrivalled experience for projects of this scale and magnitude. Engineering from Civic Engineers, design by JRA and experience and know-how from Lazenby’s master craftsmen created a steel and concrete masterpiece of exacting standards.

Hamilton Gallery’s international reputation, required Lazenby’s master craftsmanship, to maintain exacting standards. Over 150m² was installed quickly and efficiently, so that the Gallery remained closed for the shortest period possible.The deceptively simple interior design, features a 100mm Lazenby polished concrete floor throughout. The C35 mix was pumped into the period building, in one day, with concrete lorries arriving at pre-arranged times. Logistics are carefully managed, to avoid delays in the pour and avoid multiple lorries having to park in busy London streets.The floor was installed over 20 years ago and is still there today. However, it now features a lightly exposed aggregate finish, as it was accidentally painted and Lazenby were asked to bring the floor back to its albeit, slightly altered former glory.The floor now features a 'Salt & Pepper' finish with a slight fleck of aggregate showing.

Lazenby were commissioned by AHMM & Mace to install over 5,000m2 of Diamond Polished Concrete flooring to the new Hawley Wharf building within Camden Markets. Due to the incredibly high foot traffic the floor needed to be both resilient and practical. The unusual shape of the building and hundreds of market stalls meant that a tile or slabs would not have been practical and a poured in situ method was the most feasible. Lazenby installed the floors at 100mm deep, the surface was then polished to reveal the aggregate. As many of the floors are open to the elements it was critical that they achieved +36 PTV in the wet as well as having a slight fall towards the perimeter drain. As the building features multiple levels it was critical to the design that the floor finish continued on the multiple staircases within the building. This allowed the space to flow and provides a clear path for visitors to follow and explore.

Lazenby were asked to manufacture 80 completely bespoke pre cast concrete sinks for a new build office block in Kings Cross.The sinks were used in the male and female washrooms throughout all floors of the building. The sizes ranged from a 1900mm double vanity through to a 4 metre long, quintuple sink unit.All the units were cast with tap holes and a cut out for an undermounted bin chute. The joints were carefully placed to run through the cut outs to help make them as discreet as possible.The clients were looking to create a statement piece and so Lazenby created a bespoke blue colour that matched their vision. Multiple samples were created in a variety of shades before the final colour was selected.The durability and flexibility of concrete make it the perfect solution for busy washroom environments.

The nineteenth-century Ox Barn was formerly home to the oxen that once ploughed our fields. State-of-the-art agricultural architecture in its time, the clients worked meticulously to preserve the extensive beams, soaring arches and original Cotswold stone rubble walls.A contemporary counterpoint to the original barn features, our versatile Iron Grey floor beautifully reflects the rich timber while the satin finish smoothly complements the rustic textures. Over 350 m2 of our polished concrete was installed in just one week.Now, it’s a jaw dropping restaurant with a spectacular bar and a seven-and-a-half metre Charvet open kitchen.

The clients wanted a floor that could run continuously throughout. From the kitchen to the garden and pool areas…. even up the stairs. Polished concrete is one of the few materials that can be used to great effect in all of these environments.The effectiveness of the underfloor heating was of great importance to the clients. The use of polished concrete throughout the entire ground floor allowed for maximum efficiency of the underfloor heating by allowing the whole area to have fantastic thermal retention properties. All without having to compromise on style and practicality.One of our most popular shades, Off White is the perfect neutral tone to bring warmth to softer spaces – like the living room and bedrooms – and classic elegance to more functional rooms like the kitchen.The metal stair treads were installed on site ready to be infilled with concrete. We poured approximately 50mm of concrete into the pre-formed tray and then coloured and polished the surface to ensure they were a great match to the adjacent floor.

This jaw dropping project featured Lazenby Light Natural polished concrete floors and cast in situ stairs. The concrete flows from the entrance hallways throughout the ground floor and up the feature staircase to the first floor landing.This 4 week phased project saw the polished concrete floor installed first. The formwork and reinforcement for the staircase was then fixed and built off the floor. Once the stairs had been cast the brass balustrades and handrails were retrofitted to the concrete.This self-supporting concrete architectural feature staircase involved discussions with external engineers who then designed the reinforcement. The complex angles, joins to other structural elements and the sleek elegance was meticulously planned and executed. The polished concrete floor joints carefully designed to enhance the creative charm of this project.Photography by David Butler

Lazenby’s Henley Buff Polished Concrete floor was laid in a new side and rear extension to this stunning property in Cheshire.A key consideration by the clients was that the polished concrete floor be a very close match to the concrete walls which had been cast by the main contractor. Lazenby provided numerous samples for sign off before the client confirmed Henley Buff as the selected colour.The architects wanted to use industrial materials such as concrete and timber throughout the project but still wanted to achieve a warm and homely environment. This was successfully achieved by a clever use of lighting and subtle tones within the materials.To create an ultra modern, flexible space, the polished concrete floor also extends out to the patio area where it connects seamlessly with the internal flooring
