A couple of months ago I decided to try designing a wheelchair-accessible Small House using SketchUp, the 3D design software. I posted about it here in WordPress. I did both a single-storey version, sized 83 sq.metres (about 890 ft2) and a double-storey one. This post is about the internal layout of the double-storey one, featuring 3 bedrooms and 3 bathrooms. As I wrote in the previous post:
Why a Wheelchair-Accessible House?
- I think that if one builds a house, might as well make the layout and size of rooms wheelchair-friendly to make it more inclusive.
- Even if there are no wheelchair users in the household, the extra space incorporated will be appreciated.
- In the meantime, the extra space can be configured to different needs.
As for the size, I started off drawing a single-storey Small House, which is a residential structure that is considered to be up to about 1,000 ft2 (93m2), as featured in the previous post. The double-storey house featured here is about 160 m2, so it’s not considered ‘Small House’. To recap, in any case:
Why a Small House and not Tiny House?
- Tiny Houses are up to 400 ft2 (37 m2), too small to accommodate the usage of a wheelchair comfortably.
- Small Houses, bigger at between 400 ft2 and 1,000 ft2 (93 m2), would also offer the amenities of a typical house, like a ‘more regular-sized’ kitchen and bathroom.
- The single-storey version of the house featured here would be 90 m2 (about 970 ft2). This includes the ramp outside. An additional small single bedroom or study can also be added where the stairs would be in the double-storey house.
I did a double-storey version for additional bedrooms. I’m thinking that, even if the wheelchair user is single and lives alone, an extra bedroom might be useful or even necessary if he or she wants or needs a live-in carer.
I did not feature the internal layout in the previous post because I had arranged it using furniture and fittings from SketchUp’s wonderful 3D Warehouse. As I’m not sure about permission issues regarding featuring them in my post here, I decided to play it safe and draw my own furniture and fittings instead. Just some basic designs. It took me a long time, especially the kitchen appliances. An hour here, a few hours there, but I’ve finally done it.
First, some points on the changes to the external look of the house.
- Windows and sliding doors were changed to look more Art Deco since that is what inspired the design of the house.
- Ramp is now longer. With research I now know better about standards such as a 1:12 slope, for safer wheelchair use.
- The above meant having to reduce the number of side access doors, from two to one.
- House structure only, without ramp: length 15 metres (49.2 ft), width 4.7 metres (15.4 ft)
- Ramp and its top landing deck: width 1.3 metres (4.2 ft)
- Pool Module (pool, decks and planter): total length 14.5 metres (47.5 ft), width 3.6 metres (11.8 ft)
- Pool only: length 8 metres. (26.2 ft)
The ground floor consists of a double bedroom, bathroom, sitting area and kitchen.
Here is a closer look at the ground floor which is wheelchair-accessible:
The upper floor consists of two bedrooms, both with ensuite bathrooms as well as balconies overlooking the Pool Module below.
It’s been very interesting doing this. For the next house, also with Small House proportions, I’ve set my mind to drawing a flood-proof house, what with global warming, rising sea levels and the increasing incidents of hurricanes.
