Worked Solution & Example Answer:Providing for lifetime use should be a key consideration at the design stage of a dwelling house - Leaving Cert Construction Studies - Question 2 - 2022
Step 1
Using notes and freehand sketches, discuss two best practice guidelines that should be followed when designing for lifetime use at entrance access.
Answer
-
Entrance Width: The main entrance should provide a minimum clear opening width of not less than 1000 mm. This ensures that individuals, including those in wheelchairs, can easily pass through without obstruction. Additionally, a level surface at the entrance with a maximum height of 15 mm upstand should be maintained to facilitate smooth access.
-
Landing Space: It is essential to provide a minimum space of 300 mm clear space on the leading edge side of the door, enhancing ease for maneuverability and ensuring safety when entering or exiting.
Step 2
Using notes and freehand sketches, discuss two best practice guidelines that should be followed when designing for lifetime use at internal corridor.
Answer
-
Corridor Width: An internal corridor should have a minimum width of 1200 mm to enable free movement for wheelchair users and to facilitate the transport of goods. A width of 1500 mm may be recommended where possible.
-
Turning Radius: The design must allow for a turning circle of at least 1800 mm at any junctions within the corridor, enabling individuals using mobility aids to navigate effectively.
Step 3
With reference to the design shown, discuss using notes and freehand sketches, two areas of the internal layout that require specific design detailing to ensure ease of use by a person in a wheelchair.
Answer
-
Kitchen Design: The layout of the kitchen should ideally follow a 'U' or 'L' shape to provide ample maneuvering space. A turning circle of a minimum of 1500 mm should be maintained to allow ease of access between work surfaces. The worktop height should be adjusted for wheelchair users to allow access without obstruction, maintaining a comfortable counter height of around 900 mm.
-
Dining Area Accessibility: In the dining area, a clear accessible space of at least 1200 mm should be provided around the dining table for wheelchair maneuvering. The dining table should be of a height that can accommodate wheelchair users, preferably with rounded edges to prevent injury, ensuring all guests can enjoy their dining experience comfortably.
Step 4
Discuss in detail two reasons why provision for lifetime use should be considered in the design of a house.
Answer
-
Flexibility and Adaptability: Provision for lifetime use enhances flexibility and adaptability, allowing homes to accommodate changing needs over time. This is essential as families grow or undergo changes, ensuring that the home remains functional and comfortable regardless of the occupants' age or physical capabilities.
-
Cost Efficiency: Designing homes with lifetime use in mind can lead to long-term savings. By implementing features that support accessibility from the outset, homeowners can avoid costly renovations or relocations as needs evolve, making the home more sustainable financially and environmentally.
