Bourne Estate - Flat Gauge Brick Feature Arch Lintels

Bourne Estate - Flat Gauge Brick Feature Arch Lintels

IG Lintels

Bourne Estate is a Grade II listed building in the London Borough of Camden. The perimeter blocks face Clerkenwell Road, Leather Lane and Portpool Lane forming a strong uniformed frontage. Its spatial character is inward facing, with interior blocks detached and positioned in parallel rows with several areas of open space. Matthew Lloyd Architects plans were granted permission for the redevelopment of Bourne Estate. The scheme included the demolition and provision of 75 mixed tenure homes, with improved public realm and open spaces. Higgins Construction completed the £19.0m residential project using IG lintels bespoke flat gauge brick slip feature lintels.Challenge:Bourne Estate is an example of early London City Council residential housing estates built in the 1900’s. Matthew Lloyd Architects in partnership with Higgins Construction wanted to respond to the original architecture of the buildings, consisting of fine brick detailing, by emulating the pride and care shown in the old design within the new housing architecture plans. Planning permission stipulated for all materials and characteristics of the area to be retained and kept in good repair or replicated where no other alternatives are available.Solution:IG’s technical engineer designed 215mm high flat gauge brick slip feature lintels accommodating a series of brick spans; 910mm, 1360mm, 1472mm and 1585mm. All bricks were cut and bonded offsite onto the load bearing lintels.A consignment of bricks were collected from site to guarantee both quality and reliability in matching the surrounding brickwork. The ceramic bricks were carefully cut in a mitre fashion to conceal the red clay finish underneath and ensure that the ceramic finish on the mitre did not splinter which minimalised brick wastage. All the bricks cut were bonded in a rowlock pattern using BBA approved construction adhesive in a controlled environment without disruption from the natural weather. Each prefabricated single piece unit was delivered in line with the build schedule onsite. This reduced health and safety concerns by eliminating the requirement for skilled labour working from height for a prolonged period of time in a busy London area.Encompassing both buildings and landscape, the redevelopment strengthens the character of the conservation area through its careful design, by paying attention to the articulation of the facades. The contrasting brick types used on the project add to the new design creating pleasing views clearly defining key routes and boundaries.

Chichester Free School - Double Gothic Arch Lintels

Chichester Free School - Double Gothic Arch Lintels

IG Lintels

2019 Best Educational New Build at the SPACES Awards2019 Highly Commended at the Sussex Heritage AwardsVacated in 1994 and in a state of disrepair since a fire destroyed its chapel in 2009, the convent in Hunston required partial demolishing and refurbishment. IG’s gothic arch lintels played an important role in the restoring character to the original convent built in 1870 – now a central piece to the new Chichester Free School.Challenge:The £26.5m project plans, designed by Novium Architects and built by Farrans Construction needed to retain the unique single and double gothic arch windows surrounded by stone detailing. Extraordinary engineering was required to help secure the traditional architecture within the crumbling walls.Solution:The use of BIM by Doran Consulting within a Common Data Environment (Aconex) allowed their design team to integrate a digital survey of the existing convent building into the 3D models for the refurbishment to the existing and the extension of the two new school wings. This was vital in designing the new structure around the existing building, avoiding potential site clashes and to deal with complex details connecting the old building with the new, well in advance of site construction.To ensure the existing convent facades were restored to their former glory, IG’s production team replicated a double gothic arch lintels to the exacting design and measurements required. A 1580mm opening span, incorporating two 650mm wide gothic arch details, with a 430mm rise was specified – increasing the end bearing to extend the distribution of the load to the brickwork.The disused 19th century Carmelite convent has been successfully transformed into an educational facility. The new school blocks are linear in form with each wing projecting either side of the newly restored convent. The bespoke solution helped to rediscover the architectural significance of the old building as part of a new contemporary setting. The school now boasts a 600m2 sports hall, 250m2 hall and dedicated music and performance spaces for over 1280 students from reception age right through to sixth form.

Chocolate Works - Corner Lintels, Windposts & Standard Lintels

Chocolate Works - Corner Lintels, Windposts & Standard Lintels

IG Lintels

The Chocolate Works is an award winning £50.0m housing project on a strategic site bounded by York Racecourse Conversation Area and the listed Terry’s of York chocolate manufacturers building, both intrinsic to the city’s rich history. The development by David Wilson Homes, provides 320 homes including apartments and family houses. IG’s standard lintels, corner lintels and windposts provide the necessary structural support for bright and stylish open-plan spaces across multiple floors.Challenge:Since the closure of the factory, the unused industrial site had been bought and sold on several occasions. A viable scheme could not be agreed and developed to respond to the local surroundings, complementing and referencing the adjacent Grade II listed chocolate factory.Solution:David Wilson Homes used community involvement at the initial design workshop which gave local people and key stakeholders a voice in the scheme’s design. The layouts of the homes achieved are simple and clear and focus on the demands of the residents for modern and contemporary style living with high ceilings and large windows providing ample natural light.IG’s technical team designed wide inner leaf corner lintels accommodating a range of sizes for ‘The Leetham’ house type for both kitchen and study areas. IG’s corner lintels allowed for flexible open-plan spaces to be suffused with natural light through a clean and minimalistic design approach. All the lintels were supplied with customised steel support posts for each mitred corner and tailored to include factory fitted spigots located in the cavity to ensure that no steelwork was visible, with the post being encased at the corner to achieve the architectural design feature.

Holland Park Phase 2 - Hi-therm+ Lintels & Windposts

Holland Park Phase 2 - Hi-therm+ Lintels & Windposts

IG Lintels

Challenge:Driven by a respect for the environment, Heritage Homes wanted to create energy efficient homes for the future. A high sustainable build standard was required as part of their prestigious ‘Future Collection’ homes for the phase two zero carbon homes development.Solution:IG’s Hi-therm+ lintels use a patented combination of a polymer isolator and galvanised steel to bond the internal and external walls together by spanning the intervening gap creating a powerful thermal break. The one-piece lintel solution accommodated different lengths to minimise and conserve energy for each home by reducing thermal bridging at non-repeating junctions. IG’s technical team determined the loading and specification requirements at window and door openings. This fabric first approach contributed to an AA* energy efficiency rating and ensured each home built was comfortable, energy efficient and modern for years to come.IG’s LP windposts accommodated different lengths and factored into account wind load conditions. The windposts were installed into the inner skin of the cavity walls spanning vertically between the floor structures, providing additional lateral support for the large panels of brickwork and openings. All windposts included top and base place connections for fixing to the structure along with ties.Testimonial:“At Holland Park our homes are built with an AA* energy efficieny rating. IG’s Hi-therm+ lintels provided a fabric first approach to improve the thermal performance of our homes by reducing thermal bridging at non-repeating junctions”.Guy OlliverCommercial and Technical Manager at Heritage Homes

Native Bankside - Brick Feature Arch Lintels

Native Bankside - Brick Feature Arch Lintels

IG Lintels

Native’s flagship boutique aparthotel in the bankside conservation area of Bear Gardens is an eight-storey scheme that involves the transformation of three of the five buildings located within the confines of the densely packed area. IG’s brick feature arch lintels feature on the front elevation of the former derelict 19th century Empire Warehouse that has been replaced and linked into a 75-room boutique aparthotel.Challenge:SPPARC in association with Southwark Council, Macro Investments and Native wanted to demonstrate that modern architecture can successfully cohabit with the historic collection of buildings informed by the industrial heritage that dominates the southern bank of the River Thames.A carefully considered restoration and modern intervention was required for a cutting-edge contemporary mixed-use development, offering an urban experience for its users but remaining sensitive to the colourful history, conservation area and surrounding developments.Solution:IG’s technical team designed eighteen brick feature arch lintels to accommodate metal paned and arched factory styled windows. A 2718mm opening span and 143mm rise was required for each prefabricated lintel, each including a 338mm high face brick and 223mm soffit return with either a 78 or 90-degree end skew.The massing arrangement across each floor ensures that natural light is maximised throughout the building with the intricate brick detailing prominent at street level appearing above impressive double height foyer windows. The offsite construction method used negated the need for skilled brickwork to be created onsite to achieve the decorative brick pattern at a raised height. This helped to reduce any health and safety concerns in a location surrounded by tourist destinations and narrow cobbled streets.The ground floor of the scheme provides mixed use units with the northern site leased by Bell English Language School and the southern site providing studios for the iconic Globe Theatre directly linking to their Sackler Education Building.The upper floors are lighter in composition, combining clear and obscure floor-to-ceiling glazing with rich bronze circular rods, creating a strong rhythm to the façade, and enhancing the appearance of the once-dilapidated buildings. The upper floors of the Rose Alley elevation have perforated bronze screens that offer privacy, referencing the loom patterns that were once manufactured in the original warehouse.

Park Central - Bow Lintels

Park Central - Bow Lintels

IG Lintels

Crest Nicholson’s multi award-winning Park Central regeneration scheme is a fifteen-year project delivered in partnership with Birmingham City Council and Optima Community Association. Awarded ‘The Placemaking Award’ at the National Property Week Awards and recognised for regenerating the Lee Bank area in Birmingham, the scheme has created 1300 new homes promoting desirable city living. The project required IG’s special bow lintels for the final phase of 355 apartments to achieve the curvature of the façade whilst accommodating large span balcony openings and unusual loading conditions.Challenge:Glenn Howells Architect’s creative design composed of intricate brick detailing throughout the curved façade. The combination and variation of multiple bond patterns presented unusual loading conditions. A three-course stacked soldier bond pattern above window openings significantly reduced distribution of load through adjacent masonry. The heavy concentrated load carried down the brick piers and through the stacked masonry onto the central point on the lintel. IG’s experienced technical experts attended design meetings to find a viable special lintel solution for each application without disrupting the integrity and design of the architects vision.Solution:IG’s technical team designed bespoke special bow lintels to accommodate opening spans up to 4284mm and allowed for a 650mm end bearing for typical sizes to counter the cantilevered effect of the curved openings. In order to further improve the load bearing, IG designed brackets that secured into a pre-cast channel maximising structural strength at the central point of the lintel. The centrally located brackets bolted through the back of the lintel and accommodated the concentrated loads and eliminated the need to prop lintels during construction. IG provided comprehensive technical support throughout every stage of construction process for the most effective structural design solution.Testimonial:“The development has been a resounding success in transforming and rejuvenating the Lee Bank area in Birmingham. IG’s technical team were responsive and receptive to all urgent requirements throughout every stage of the construction process. An outstanding technical service that we have come to expect from IG.”Crest Nicholson
