BRIEF

ESSENTIALS:

SITE CONTEXT

• 2 x BEDROOMS for volunteers with on suite bathrooms

The project should embrace the views of the mountainous valley visible

• 1 x MEETING ROOM (for Himalayan Aid meetings) that can also be

from the lower and upper levels of the building, and the peaceful location.

used as a LIVING ROOM (for volunteer’s relaxation) • 1 x self sufficient KITCHEN for volunteers (volunteers have the option of cooking for themselves)

The existing building is a concrete structure with some ornamental stone cladding. Timber framed windows and doors are used throughout.

HIMALAYAN AID PERSPECTIVE: Provide adequate accomodation for volunteers to make them feel at home, and encourage them to stay volunteering for long periods of time.

Build an extention to the existing Himalayan Aid Office that considers the principles of earthquake resistant buildings, rapid construction, availability of materials and respects the NGO’s reasonably low budget.

VOLUNTEERS PERSPECTIVE: Privacy is an issue when living in the village. When coming from another country and another culture, privacy is one of the things that volunteers will miss. The design should try to consider this, and at the same time embrace the sense of community that Nepali communities thrive on.

Volunteers should also have the option to cook or prepare food for themselves, as the Nepali Dhal Bhat staple is somewhat overwelming when eating this meal twice a day, every day, for any extensive period.

03 - STRUCTURAL CONCEPT Extension for Himalayan Aid Headquarters

STRUCTURAL CONCEPT The existing building has 5 primary structural beams (highlighted in blue).

These define the structural grid of the extension and help to shape the layout.

primary structural beams

STRUCTURAL CONCEPT The primary structure will be made out of steel. 3’’x 3’’x 3mm steel square pillars will hold a steel truss made offsite from 2’’x 2’’ x 3mm steel extrusions.

STRUCTURAL CONCEPT Window and door frames are fixed directly to the steel structure. Plasterboarding is used for internal finishing (modern white), fixed to steel structure via wood battons.

STRUCTURAL CONCEPT For thermal comfort and avoiding sound pollution, insulation is key to install in the cavity of the wall. Insulation could be made from 2/3 layers of floor matting (foam) commonly found in nepal, or compacted straw bricks (found in weat fields).

The area highlighted in purple shows where insulation is required.

Thermal and sound insulation

STRUCTURAL CONCEPT Timber cladding provides a natural finish, resistant to wet/dry/cold weather. It also provides an opportunity to source the material locally, helping the local economy and avoiding possible problems with deliveries (not to mention a reduced carbon footprint).

A concrete upstand on the perimeter of the building raises the internal and external finishes from the ground, helping to avoid internal plasterboard and external wood cladding to get damp and degrade.

STRUCTURAL CONCEPT When it rains, tin roofs make a lot of noise. This is uncomfortable for users of the building.

Insulation in the roof will reduce the large levels of noise pollution during storms.

A timber soffit and a side facia board help towards concealing the tin roof, and give the impression of a traditional house roof (timber and tiles).

It is very important for the facia board to cover the tin edges.
