Fu­ture fo­cus

House and Leisure Before and After - - RENOVATION #6 -

The belief that homes can be bet­ter is what mo­ti­vated the de­sign be­hind a re­cently built model home by Saint-gobain, a com­pany whose phi­los­o­phy is to in­vent prod­ucts that im­prove qual­ity of life. Named Stand 47, the struc­ture demon­strates en­vi­ron­men­tally friendly, sus­tain­able, and cost-ef­fec­tive con­struc­tion meth­ods and build­ing tech­nolo­gies that are avail­able in South Africa right now. The in­ten­tion was to demon­strate that it’s pos­si­ble, within these con­struc­tion guide­lines, to build an ap­peal­ing, con­tem­po­rary house that can stand the test of time and yet be flex­i­ble enough to adapt to the fu­ture needs of the in­hab­i­tants.

The home was built on a serene, ex­pan­sive site near a row of long-es­tab­lished trees on Mon­aghan Farm, a 520-hectare es­tate and work­ing farm near Lanse­ria air­port in Johannesburg.

The core of the house is a light steel frame­work, which is said to be 21 times more flex­i­ble than tim­ber and 10 times more re­in­forced than con­crete, and re­sis­tant to mois­ture, fire, cor­ro­sion, storms, ter­mites and other pests. The con­struc­tion time is also re­duced as it can be as­sem­bled rapidly with­out spe­cialised equip­ment. Steel is also made from re­cy­clable ma­te­rial and is free of tox­i­co­log­i­cal and al­ler­gic ef­fects. There are al­ter­na­tives to tra­di­tional brick-and-mor­tar

con­struc­tion and in­te­rior so­lu­tions com­pany Saint-gobain was de­ter­mined to demon­strate this

with an in­no­va­tive con­cept home

The in­no­va­tive ma­te­ri­als used in the for­ma­tion of the in­ter­nal walls com­prise prod­ucts fea­tured in the Saint-gobain cat­a­logue – in­clud­ing Gyproc Ac­tiv’air, which ac­tively im­proves in­door air qual­ity by ab­sorb­ing up to 70 per cent of formalde­hyde, which makes up the largest pro­por­tion of volatile or­ganic com­pounds in the air, and Gyp­wall Du­ra­line, a high-im­pact-re­sis­tant dry­wall sys­tem that han­dles heavy traf­fic ar­eas such as cor­ri­dors and pas­sages.

In the case of a fire, the sur­vival of oc­cu­pants greatly de­pends on their speed of move­ment, which is why it is vi­tal to buy them time to move to a place of safety. With a core of glass fi­bre and ver­mi­culite, Gyproc Firestop used at Stand 47 can slow down the spread of flames for up to 120 min­utes of­fer­ing a high level of fire pro­tec­tion.

To an­swer the needs for dry­walling in high-mois­ture ar­eas such as the kitchen and bath­rooms, Gyproc Mois­tur­ere­sis­tant board which has wa­ter re­pel­lent ad­di­tives in the core, was used.

Sound in­su­la­tion is guar­an­teed with the help of non-com­bustible glass wool cav­i­ty­batt, which also of­fers ex­cel­lent ther­mal in­su­la­tion com­pared to ma­sonry.

Key to these build­ing ma­te­rial choices is the ethos that the home should be change­able and hard wear­ing, with a ca­pac­ity to adapt

to new needs and func­tions, but also ef­fi­cient and ar­chi­tec­turally in­no­va­tive. The hy­poth­e­sis is that a bet­ter process leads to a bet­ter home and the re­sult is a suc­cess story that ticks all the boxes, and which ul­ti­mately pro­vides in­spi­ra­tion to South Africans look­ing for al­ter­na­tives in build­ing ma­te­ri­als and meth­ods that fo­cus firmly on the fu­ture.

CLOCK­WISE FROM ABOVE The home is built us­ing a light steel frame with Saint-gobain ma­te­ri­als as in­fill, mak­ing fu­ture adap­ta­tion and ren­o­va­tion easy; or­ganic ma­te­ri­als such as tim­ber have been used to con­trast the clean lines of the in­te­rior ar­chi­tec­ture; the ETICS ex­ter­nal wall cladding sys­tem is made up of a num­ber of lay­ers.

CLOCK­WISE FROM TOP LEFT The walls in the bed­room con­tain Ac­tiv’air, a spe­cial Saint-gobain Gyproc prod­uct, which im­proves the air qual­ity in the bed­rooms; a large over­hang wraps around the east, north and west, shad­ing the edges of the home in sum­mer, but al­low­ing sun into the home in win­ter; the light steel frame be­ing con­structed; the open-plan liv­ing and din­ing area com­bine a num­ber of ma­te­ri­als and tex­tures.

House and Leisure read­ers are in­vited to join Saint-gobain for an in­for­ma­tive tour of the Stand 47 con­cept home on Satur­day 16 May 2015 where you will be in­tro­duced to the build­ing tech­niques ap­plied dur­ing the con­struc­tion of the home. Visit stand47.co.za to book a space on one of the three tours that will run dur­ing the day.
