Part B
BOULMER LIFEBOAT STATION
SOLUTIONS AND IDEAS
BRIEF:
conversion/ retrofit of an existing lifeboat station, located on the North East coast af Boulmer (just East of Alnwick).
KEY: Keep Remove
The brief for the building consists of conversion of the 5 main areas of the existing building into a learning/ teaching centre for school groups. I have decide to convert the lifeboat station into a health and lifestyle center that offers a “healthy cafe�. During the summer season there will be space available for barbaquees as well as outdoor sitting area and potential roof space seating depedending on the final design. The gym will be accessible to both the locals and tourists visting the village. A small studio will also accomidate the
EXISTING
gym. I decided to contact one of the volunteers at Boulmer lifeboat station to find out more about what facilities where available.The nearest fintess facility is located in Alnwick or the RAF military for military personel. With an ageing population, as well as statistics Boulmer is a relatively healthy village, yet such facilities are not provided. The aim of the fitness center is to not only bring the community together

LAYOUT 1: New build
CASE STUDY 1 A 104 year old grade II* listed lifeboat station with “one of the best sea views in Britain” is up for sale, as its current occupiers seek more modern and practical quarters. Nestled in a national park on the Pembrokeshire coast, St. Davids RNLI station would (with a bit of work) offer a truly incredible seaside get away or holiday home for anyone who could afford it, either for themselves or as an investment. St. Davids lifeboat house stands about an hour’s drive away from The Old Tenby RNLI station, which was famously renovated and converted into residential accommodation by Pembrokeshire architect Michael Argent in what viewers described as “the greatest ever” episode of Grand Designs
CASE STUDY 2 Rustic
to modern:
A stunning 300-year-old stone barn in Hereford, United Kingdom is now a modern home with prefabricated interior spaces, a wooden addition and the integration of large glass windows to bring in more daylight. The Hillcott Barn by RRA Architects boasts an interior made of individual prefab pods which were constructed off-site and simply lowered into place in each room via crane. This method of construction not only saved the owners money, but helps preserve the original stone structure. The roof was also modified to improve ventilation and add more daylighting, and the barn door openings were fitted with large glass windows.

Pro’s
Potential Issues?
English firm McGarry-Moon Architects turned a stone barn positioned in Broughshane, Northern Ireland, Uk into a picturesque cozy present day countryside residence. “The dwelling retains the integrity of the current barn whilst hinting to the dynamic design and style inside. The new constructing employs the foundations and outer walls of the outdated barn all original openings are utilised without having alteration in the reduce ground floor.”

FOUNDATIONS
GENERAL INFORMATION
Once on site, containers are crane lifted one by one on to the foundation slab, hooked into place and welded down. * with only 1 main road into Boulmer via the motorway using a crane may be difficiult especially with the low tower bridge and the weight of the containers, carefully consideration and analysis will be rquired to ensure that the containers can arrive on site. The detail provided indicates how all the corners are welded to steel plates. Metal hat channels for wiring are run along the walls and vertical support beams are secured. Metal studs and dry- existing container wall are used for in- walls are faced terior partition walls. in drywall for Once insulated, the finishing.
ROOF One of the main disadvantages of using containers is the structural integrity of the roof is very poor in comparison to the corners. As a result careful detailing is required to ensure that the weight of both the dead and live loads imposed on the roof can safely be transfered to the foundations. A typical 20’ steel container is designed to have a maximum gross weight of 52,910 pounds. The container must be capable of withstanding imposed loads of 2g downwards, 0.6 lateral and 2 g longtitudinal inaddition to the stacking of around 8 containers. Thus the roof is able to support an imposed load of 330lb/sp.ft These figures are based on ISO 1496/1.
In 1955, after development post-World War II, shipping containers were built to standardised sizes which were adopted globally for efficient freight transportation. The strength of their design allows for up to 26 tons of cargo to be carried and stacking of the containers up to eleven units high. Distances travelled can be upwards of 50,000 miles a year with all containers requiring a valid Container Safety Certificate in order to be classed sea worthy. Shipping container’s qualities make them ideal structures for Green Roof Shelters: *Incredibly strong and rigid structure to support our 225kg/m2 biodeverse green roof *Inherently durable COR-TEN steel * Selection of sizes: 3m/6m/12m by 2.4m allowing for many adaptations (Bike storage, garden room, classroom etc.)
GREEN ROOF
OPENINGS:
Below is a detailing of a container green roof composed of planting medium ( roofrug), waterproof memborane, insulation & plywood. One of the main issues with flat roofs in particular is standing water, eventhough green roofs absorbe as much water as they possibly can in order to grow, water will still have to be drained. The detail provided shows a conventional side gutter and weep hole
More than likely will the containers be modified, whether that is to create an opening for windows, doors or dtairs, the structural integrity of the container will be compromised. TO ensure that the container is stable steel reinforcement will be required. All the openings are measured and cut offsite. All openiing should be framed with a steel section
PASSIVE SOLAR HEATING PASSIVE SOLAR COOLING Primary elements of passive solar:
Wing walls:
Wing walls are vertical solid panels placed alongside of windows perpendicular to the wall on the windward side of the house. Wing walls will accelerate the natural wind speed *South facing glass *Thermal mass to absorb, store & distribute due to pressure differences created by the wing wall. heat
Approaches to passive systems: *Direct gain *Indirect gain *Isolated gain
Thermal Chimney:
A thermal chimney employs convective currents to draw air out of a building. By creating a warm or hot zone with an exterior exhaust outlet, air can be drawn into the house venDirect gain: tilating the structure. Sunrooms can be designed to perform The living space becomes the solar collector, this function. The excessive heat generated in a south facing sunroom during the summer can be vented at the top. With heat absorber and distributer. The direct gain system will utilize 60-75% of suns ener- the connecting lower vents to the living space open along with windows on the north side, air is drawn through the living gy. space to be exhausted through the sunroom upper vents. (The upper vents from the sunroom to the living space and Principle: any side operable windows must be closed and the thermal mass wall in the sunroom must be shaded.) *Dark colours for floor *Do not cover thermal mass floors with wall to wall carpeting
CHARRED TIMBER
THE THIRD RULE Cantilever “one-to-three”. Cantilevered steel beams are commonly used to support architectural features, giving the illusion of an unsupported or “flying” edge. How far is too far for a cantilever to stick out? Generally speaking, So if your beam has a 30’ backspan, try to keep an adjacent
cantilever to less than 10’ long. if a cantilever exceeds 1/3 of the total backspan, economy is lost and may lead to design difficulties.
This method of burning the surface of wood building materials began in Japan during the 1700s. Since Japanese builders traditionally used cedar, as well as cypress, the process is called shou sugi ban, or “burnt cedar.” But as passive solar and LEED certification become mainstream architectural concerns, architects are continuing to search for environmentally sound techniques to incorporate into their practices. Using charred wood for construction is a viable eco-friendly option, particularly since this completely natural manufacturing process requires only fire and wood; the harsh chemicals used in pressure-treated lumber are eliminated. It also yields an extremely durable building material. Wood treated with fire is paradoxically fire resistant, as well as resistant to insects. The material is also durable due to its low reactivity and is rated to last 80 years. Integrating it into house designs gives not only interesting aesthetic possibilities, but environmental and structural benefits as well.
Aesthetically the shou sugi ban can look like a dark stain or have a surface texture similar to alligator skin. The finish depends on the extent of the exposure to fire, as well as the amount of char cleaned off after the process. Houses with exterior trim done with the method appear to shimmer, and change from silver to black depending on sunlight.
