Worked Solution & Example Answer:The drawing shows the elevation, ground floor plan and portion of the rear garden of a two-storey semi-detached house - Leaving Cert Construction Studies - Question 3 - 2013
Step 1
Show, using notes and freehand sketches, a proposed design for the extension to the rear of the dwelling house and a revised layout for the ground floor to include the extension.
Answer
Proposed Design for the Extension
- The building footprint is optimized to face south, maximizing sunlight exposure.
- Incorporating climate-responsive window-to-wall area ratios to enhance natural light while minimizing heat gain in summer and heat loss in winter.
- A high-performance low-glazing system will be added, allowing ample natural light and providing views to improve occupant well-being.
- Design for the roof will promote natural light into the house.
- Increased glazing on the southern façade to allow greater access to natural light.
Revised Layout for the Ground Floor
- Increased floor area provides more space for relaxation and a view of the garden.
- An open plan design enhances the flow between spaces and keeps the areas feeling spacious.
- Adequate shading features will be integrated to reduce glare and manage thermal comfort.
- A new access point will be included to connect the garden directly to the living space, promoting interaction with nature.
Step 2
For each of the above, discuss in detail the reasons for your proposed design choices.
Answer
Increased Sunlight
- Optimizing sunlight is crucial for improving energy efficiency and natural light within the home, thereby enhancing the health of its occupants.
- Utilizing the south-facing aspect allows for the maximum amount of sunlight during the day.
- Increased natural light has been proven to benefit mental health, reducing feelings of lethargy and improving overall well-being.
Improved View to the Rear Garden
- Providing a clear view of the garden connects occupants with nature, fostering a sense of calm and enjoyment.
- Garden visibility promotes biodiversity, as residents can enjoy the natural environment, gardening, and the beauty of wildlife.
- Features like large windows will not only enhance the aesthetics of the home but also increase the perceived space, making the interior feel larger and more inviting.
