Sika Sarnafil branches out with unique garden room project

In possibly the only building of its kind in the UK, Sika Sarnafil single ply membrane has been used to waterproof a garden room with a live tree growing through it.

Hackney-based architect, Andrew Leckenby, specialises in working with private clients to improve their homes. But when it came to extending his family home, Andrew became his own client. Living in an urban area meant imagination was required to increase his living area.

SINGLE-PLY MEMBRANE

Deciding to make the most of his home’s outdoor space, Andrew settled on a garden room. However, the rear of the garden contained a beautiful false acacia tree, which he did not want to remove. Thinking outside the box, Andrew drew up plans for a room that would incorporate the tree, making it the focal point of the space.

Andrew explained: “There are countless examples of trees being integrated with architecture – but these are generally found in countries where it doesn’t rain quite as much! To be able to achieve the same effect in the UK, we needed a roofing membrane that was flexible enough to allow the tree to sway and grow, as well as being durable enough to keep the building watertight.”

Andrew had specified Sika Sarnafil on many extensive commercial projects during his career working with larger architectural practices, so knew that the product would meet his requirements.

SINGLE-PLY MEMBRANE

“Faced with a challenging roof design, I instantly thought of Sika Sarnafil. As the industry leading single ply membrane, after decades of specifying it for corporate clients, I was confident that I could trust its quality and durability. In addition, Sarnafil’s Registered Contractor scheme allowed me to identify an installer that had the training and experience to do the job – essential for detailing of this nature.”

The finished article is a striking, yet homely multi-functional space, used as a garden room that extends the summer season, a home office – and not to mention a unique sleepover location for Andrew’s son.

SINGLE-PLY MEMBRANE

A member of the Sika Sarnafil technical team inspected the project once complete and awarded a 15 year guarantee on the roof. The low maintenance membrane means Andrew only has to check the waterproofing once a year to ensure the detailing around the tree is still sound. A small price to pay, says Andrew, for such a fantastic family space.

Nick Knowles of DIY SOS with Rachel Levy from Big Foot Systems in the rooftop garden at Great Ormond Street Hospital

Big Foot Systems is thrilled to have helped Nick Knowles & the BBC DIY SOS team on a rooftop garden project at Great Ormond Street Hospital for children in London. The company supplied its very popular H Frame supports as part of the project which involved the creation of a rooftop garden area – a space which will provide a much needed sanctuary for children, carers and families at Great Ormond Street Hospital.

The garden, designed by Chris Beardshaw, had its public debut at RHS Chelsea Flower Show on 23 May 2016 where it received a gold medal. The award winning garden was then moved and adapted by the BBC DIY SOS team so it could be permanently sited at the hospital. The ambitious project features over 30 mature trees, around 1,000 plants, over 30 tonnes of soil, and took over 70 crane lifts to reach its destination in the centre of the hospital on the roof of the old boiler house.

The transformational space is now a charming garden featuring symbolic references to the relationships between children, parents and clinicians, something which designer Chris Beardshaw was keen to highlight in the design. At Great Ormond Street hospital there was a real need for somewhere close to the wards which could offer a calm and reflective space for those who need it, even if it is just for a few moments, the new rooftop garden provides this calm peaceful space.            

Speaking of the company’s involvement in the project, Big Foot Systems Product Manager, Sam Birch said “When we were contacted and asked to provide some products for the DIY SOS Great Ormond Street Hospital project, we jumped at the chance to be involved. This is such a worthy cause and one which, as a company we were more than happy to be involved in. We were also honoured to be invited to the official unveiling of the finished garden which had gone into it was very impressive”.

The DIY SOS programme, which airs on BBC One on Thursday 10 November at 20:00, shows the huge efforts which went into the design and build of the garden space both on and off screen – a massive success for all involved.

At the Great Ormond Street roof garden Big Foot’s H Frames were used to support and distribute the load of a wall in the roof garden. Quick, versatile and economical, Big Foot’s H Frames are traditionally designed to support pipework, duct, cable ladders/trays or any combination of these in construction projects, helping to ensure a safe and secure flat roof. Offering a versatile application, installers provide their own strut keeping the duct and pipe installations low-cost by fabricating the strut frameworks on site. Featuring an innovative design, the H Frame Set 305mm is interchangeable with three strut sizes with one foot fitting all. The support is also compatible with industry standard componentry also adding to application flexibility.

RonaDeck Resin Bound Surfacing – not just decorative

Resin Bound Surfacing

There are a variety of resin bound surfacing systems appearing on the market, all claiming to do the same job – provide a decorative, functional permeable paving system. All seem “much of a muchness” apart from price.

However, resin bound surfacing systems can differ not only in quality and longevity but in other factors such as slip resistance, sustainability, health and safety and cost per square metre. So what features should be considered?

Standards

Currently there are no set standards in resin bound surfacing; it is therefore worth looking at the following credentials which are indicative of a reliable manufacturer.

ISO 9001 certificate – the accreditation for a company’s quality management systems.

ISO 14001 certificate – the accreditation for a company’s environmental management systems.

OH SAS 18001 certificate – this accreditation is the British Standard for occupational health and safety management systems.

FERFA membership – FERFA is the leading authority for 40 years on resin flooring systems. FERFA members subscribe to FeRFA Codes of Practice requiring high standards of operation, management, technical service, health & safety and business integrity.

Types of resin

The best resin bound surfacing systems use aliphatic resins rather than aromatic resins. An aliphatic resin is preferable to an aromatic resin because it will not yellow or darken in sunlight or become brittle when exposed to UV light.

Ratio of resin to aggregate

This should be minimum 7% to ensure consistent strength and performance of the system. Any less can drastically reduce the performance of the system.

Application thickness and the cost to the environment

This can vary, but a good quality system should be laid from 15mm for pedestrian traffic and 18mm for vehicular traffic. Cheaper resin systems need to be laid thicker meaning project costs go up whilst more materials transported to site make the system less environmentally friendly.

Slip resistance

A good system should conform to BS 8204-6:2008+A1:2010 Appendix B. Aggregate blends can vary in their slip resistance but all should achieve ’low potential for slip’ in both wet and dry conditions. Using Pendulum Test Values (PTV) the risk of slip categories are graded as follows:

0 – 24 = High Slip Potential

25 – 35 = Moderate Slip Potential

36+ = Low Slip Potential.

Quality control

A two part system where the catalyst is built into the manufacturing process should only be sourced. Systems that require a catalyst to be added by an operative on site rather than a chemist increase the risk of poor performance through guesswork.

Permeability – SuDS compliant system

A resin bound surfacing system should be permeable, but permeability rates can vary depending on the aggregate size.

So to sum up resin bound surfacing systems can vary greatly in terms of consistency and performance. Check the manufacturer’s data sheet carefully and remember if a feature isn’t listed, it is probably because the product does not have that feature!

If you are still unsure then ask for technical help, the Ronacrete Technical Department will be happy to assist.

Chelsea Flower Show – Brewin Dolphin Garden

RonaDeck Resin Bound Surfacing was laid to a floating pathway running through an award winning garden at Chelsea Flower Show 2016. The aggregate selection included crushed glass blends of green, blue and purple.

The Project
“Forever Freefolk” the silver medal winning garden at the 2016 Chelsea Flower Show was designed by Rosy Hardy and sponsored by Brewin Dolphin, the main contractor was Bowles Wyer. The garden is based on Freefolk, Hampshire and the high security paper-making industry supported by the River Test located near the designer’s nursery.
.
Ronacrete Approved Contractor, Graveltech were selected as installers of the RonaDeck Resin Bound Surfacing on the raised pathway that wound itself through the garden.
“I wanted a path that sparkled picking up the colours of my planting. The glass resin paving fitted the bill completely, looking great in bright sunlight and duller conditions.” Rosy Hardy, Garden Designer

Rosy Hardy’s nursery is situated on chalk downland close to the River Test which is a typical example of a chalk stream. The chalk provides an excellent filter for the water so that it is extremely pure. For this reason the water in the River Test was used by the Huguenots, when they moved to the area in the 1730s, to watermark banknotes. The Huguenots also realised the importance of preventing forgery and so ran a silver thread through the bank note, this is reflected in the garden by the stream running through it and by the resin bound pathway that follows the stream.

Visitors are led along the path through a dry chalk stream bed towards its source. The route takes them through shady, dry chalk, grassland and damp areas with appropriate plants for each landscape.

Another idea came from a picture of a fishing hut floating above the River Test, this resulted in the creation of the floating pathway running through the garden. A spherical aluminium sculpture provides the focal point of the garden and hovers above the resin bound pathway. This was inspired by how the chalk beds were formed. Coccospheres are the calcium carbonate skeletons of plankton that washed up on the seabed and form the main constituent of chalk. So a coccosphere was sculpted from aluminium and placed in the garden.

Product and Application
The RonaDeck Resin Bound surfacing was laid to the floating pathway by Hertfordshire based, RonaDeck Resin Bound Approved Contractor Graveltech. A selection of specialist aggregate blends were included that included crushed glass in green, blue and purple.

Conclusion

Of the 160.000 visitors attending this great British summer event, a great percentage will have visited this award winning garden and stood on the resin bound pathway to admire not only the surrounding colours but those beneath their feet.

Brett Revives Courtyard At National Centre For Circus Arts

Circus-Arts-3-lo-res-e1464881205931

Brett Landscaping recently supplied over 700m2 of paving to installers Marshall K Paving Contractors Ltd for installation at the National Centre for Circus Arts in London.

The centre, which is based within a former Victorian power station in Hoxton Square, is of one Europe’s leading circus skill educators and was the training ground for performers involved in the 2012 Paralympic and Olympic opening ceremonies.  In addition, the impressive building is a sought after venue and offers a unique selection of city spaces for event hire.

Director of the Centre, Jon Dix explains:

‘One area of the building, the Courtyard, was earmarked for renovation, but due to a seven-day-a-week timetable and the area being in continual use, this had to be done within a very tight timeframe.’

The Operations Team at the National Centre, headed by Jon, investigated potential solutions at the 2015 London Home Building & Developer Show held at ExCeL in September, and discovered that Brett Landscaping, with its strong focus on customer relationships, could offer more than just the essential materials.

Brett was subsequently considered, alongside other suppliers and contractors, as part of a tendering process to select the right partner for the paving scheme.  He explains:

“After comparing a number of different paving products, all of which had their merits, the range of options we had from Brett faired strongly and provided us with an excellent starting point for the project. In addition, the service we experienced from the team was very thorough, which made our experience more than about simply ‘picking the best brick’, or ‘nicest material’, not just with Brett, but with the subcontractor too.”

“Aesthetics were a key consideration. There aren’t many Victorian power stations in the heart of London that are still standing, let alone operating with a new purpose, so we felt it imperative to re-lay and improve the Courtyard area of the circus centre as sympathetically as possible so as to do justice to the building’s impressive looks.

Jon goes on to explain how 700 m2 of Brett Aura block paving in Silver Fleck was selected to create an extremely effective Courtyard visual; however the building’s central Hoxton Square location meant more than just the right materials were needed for the job.

The area prohibits the use of articulated lorries in fulfilling deliveries, a complication which meant both supplier and installer needed the logistical capabilities to work with restricted motorised equipment, as well as the aptitude to turn the project around within two weeks, in time for a scheduled acrobatic symposium.

Jon Mathias, the Brett Approved Installer Area Manager for the South East, explains that because Brett successfully operates its own ‘Brett Approved Installer Scheme (BAI)’, it can recommend installation specialists with the right match of skills and infrastructure to accomplish every project.

“We recommended three of our BAIs to Jon Dix and his team, enabling them to receive quotes and completed work examples from each, alongside quotes from other independent contractors.”

Based on Brett Landscaping’s recommendation, installer, Marshall K Paving of Cricklewood, was selected as the most appropriate choice, and since appointment, has worked within impressive time constraints to complete what the company’s Director, Kevin Canning, has described as a ‘fantastic project in a challenging location’.  He explains:

“Owing to the vehicular constraints in the Hoxton Square area, Brett arranged special delivery of materials to the Deben Buildbase in New Southgate, from which 18 tonne flatbed deliveries to the circus centre site were made, with appropriate crane off-load at the Hoxton Square end.  This logistical process proved successful, and avoided the expensive option of closing roads around the Shoreditch area.

“Our installation team then worked to complete the Courtyard in five days, over the course of a two week time period, despite adverse weather conditions and complex parking restrictions.

“The finished result looks extremely effective and we’re delighted to have completed the project in advance of the acrobatic symposium event.”

“Being part of the BAI scheme improves standards across the board. Brett only selects hard landscaping contractors who are able to install materials to the approved British Standard, and because Brett regularly assesses our work, the benchmark remains high.

Brett supports its approved installers too, not only in helping to procure business, but to purchase equipment and publicise their services.”

Now completed, the Courtyard at the National Centre for Circus Arts is being put to use, and has a busy itinerary of event bookings to look forward to.
Jon Dix concludes: “We’re delighted with the finished Courtyard. Our objective was to revive the area with re-laid setts that were sympathetic and appropriate to the aesthetic of the building.  By working with Brett Landscaping, and Marshall K Paving, we have achieved exactly that.”

Charity’s rejuvenation project uses striking Brett Landscaping solution to draw footfall to Hull “Old Town” Centre

brettHull Trinity House, a charitable organisation which has served seafarers and their families in the area for over 600 years, has successfully regenerated part of Hull’s Old Town, using hard-landscaping materials supplied by Brett Landscaping.

With an inspiring colour spectrum and capacity for creativity, products from the Alpha Antique block paving range were considered the perfect choice for the charity to create a striking new and much needed car parking area, which doubles as an outdoor entertainment space.

900m² of Alpha Antique in Brindle was installed with its distressed aged look blending beautifully into any surrounding, whilst its subtle tones evoke a warm ambience making them ideal for period settings such as Hull Old Town.  Alongside the Alpha Antique, white marker blocks were also used to denote parking spaces, all of which was installed by the main contractor, C R Reynolds.

The privately funded redevelopment has transformed the former site of the Trinity House School, whose premises were deemed unfit for purpose in 2013.  The school consequently relocated to a more appropriate site, leaving the charity consigned with a redundant building.  As the former school structures were considered ‘detrimental to the Conservation Area’ by the Local Authority Planning Department, plans to rejuvenate the land were discussed, as Mr Outram, Estates Manager, explains:

“With Hull town centre experiencing a decrease in footfall, we wanted to convert the school’s land into an area where the local community would want to visit and spend time.  Our solution was to devise a scheme that would generate vital car parking space for shoppers and, more importantly, create an area where outdoor events could take place, adding a new dimension to Hull’s city centre.

“To successfully achieve this, exceptional quality paving was required to both harmonise with the conservation area, and meet with guidelines specified by the local planning department.”

Mr Plaxton, Assistant Estates Manager, a co-designer and project manager for the scheme, also became an integral part to the building materials decision process.  He required a superior product which was not only resilient but also visually stunning.  With helpful recommendations from his local merchant, he found the perfect product through Brett.

“Brett Landscaping was able to offer an extremely attractive, yet robust, solution using materials from the Alpha Antique block range.  These beautiful blocks created the perfect look, and their installation went extremely smoothly.”

Here Mr Plaxton refers to the performance of contractors, C R Reynolds, whom, in order to keep the project on track, needed to take delivery of the Alpha Antique paving blocks within a pedestrianised area which meant that there were delivery time restrictions.  He continues:

“The site is situated within the old town centre and is surrounded by narrow cobbled streets which have restrictive access issues.  C R Reynolds performed superbly on the project, meeting timescales and producing a standard of finish that met with our high expectations.”

With the installation now complete, the newly developed site is ready to help attract more visitors to the town centre.  Live events are scheduled to begin in summer 2016 and any profits made from the car park and event space will be assigned to benefit educational purposes.

Andrew Gill, Marketing Manager of Brett Landscaping, is delighted to hear about the charity’s positive experience and agrees that the finished result looks outstanding:

“The Alpha Antique blocks look terrific in situ and have been installed to the highest standard.  The finished effect is truly striking, complimenting the surrounding area and making this new community area very inviting.  The quality of the product really does shine through.  It’s a job, extremely well done.
