Homes without barriers: A guide to accessible houses
For most of us, the word 'home' means a place of comfort, a refuge, a place where we can be ourselves and relax. For people with disabilities or those growing older, home has a special importance because they are likely to spend more time there. But when physical barriers and poor design make that home difficult to live in, health, safety and happiness can be compromised.
Designing and adapting houses in a way that enables people to really live in their own home for longer makes sound economic as well as emotional sense. It will lessen dependency, lower the risk of accidents, reduce the cost to society and possibly even increase the resale value.
This guide is about houses that are not disabling. It was developed in conjunction with many people working in the health and disability fields. It is packed with diagrams and advice for building designers, builders, health professionals, homeowners and anyone involved in the design or alteration of houses for those with disabilities or the elderly.
Module: Introducing bracing
Forces from wind and earthquakes place demands on a building. These demands are calculated for a particular building so that the building can be designed with enough bracing capacity to resist the demand and perform structurally.
Topics covered in this self-paced module:
- Wind bracing
- Earthquake bracing
- Library
Gain 100% in the test at the end of the module, and you'll receive a record of your completion that can be submitted as part of your CPD activity log.
Renovate: Art deco
The art deco house of the 1930s was a dramatic change to the earlier villa and bungalow. A flat roof, stucco cladding, rounded corners and reduced decoration all contributed to art deco's distinctive style.
These houses are often bought for their style rather than performance. Their stucco cladding and very low-pitched roofs often had weathertightness problems, and without renovation, art deco houses can be cold to live in. Careful renovation can retain the popular style while improving performance and comfort.
This book covers:
- what defines art deco style
- how these houses were constructed, and with what materials
- typical modifications they have had in the decades since they were built
- problems that may be encountered and suggested remedies
- how to get a consent for renovation work, looking at compliance paths and Alternative Solutions
- project and construction planning.
