为什么不让所有的家庭都可以访问呢?

Few would deny that it’s taken far too long for the world to face up to climate change, but something much more fundamental has been overlooked, not just for decades or even centuries, but for millennia. I’m talking about growing old.

Across the world we have been painfully slow to factor ageing into the way we design and construct the built environment. Even societies that revere older people for their wisdom and care for them in extended families have given little thought to eliminating the physical barriers which limit so many lives. The view that older people, and those living with disabilities, are “better off at home” has become widely entrenched: including in Britain. Ironically, we failed there too; the concept of accessible housing is barely 30 years old, and it’s been a tortuous journey so far.

Lifetime Homes, a 16-point standard devised to make life easier for older people, was developed by the Joseph Rowntree Foundation in the early 1990s. Respected by some but resented by others (including many designers) as a voluntary standard, it gained relatively little traction and not all of it made sense. The fact that walk-up flats could still achieve Lifetime Homes status was a major anomaly.

In 1999 a watered-down version was taken into regulation through Part M, which until then had only dealt with public buildings. This gave weight to the issue but was painfully inadequate in terms of content, requiring, among other things, step-free access to the main entrance (unless that was too difficult …), and a small, ground-floor WC (unless there were no habitable rooms on that level …).

Having ignored the implications of rising life expectancy for so long, we have a huge amount of catching-up to do

The inadequacy of Part M meant that, despite its flaws, the full Lifetime Homes standard lived on for another 16 years and was often cited in planning policy. It was all very messy.

In 2015 two higher levels of accessibility (“optional requirements”) were added to the meagre baseline in a new volume of Approved Document M. The baseline was renamed M4(1) Visitable dwellings (or category 1) and remains the default. The two optional requirements, M4(2) Accessible and adaptable dwellings (or category 2), which is very similar to Lifetime Homes, and M4(3) Wheelchair user dwellings (or category 3), must be justified before being invoked. Local planning authorities are required to prove need and viability before defining the proportion of new housing that should meet each of the optional requirements. The category 2 and 3 homes are listed in the planning conditions, but testing falls to building control.

The government expected most local authorities to opt in and require something like 30% to 50% of new homes to meet category 2, and 5% to 10% to meet category 3. In practice the proportions vary from 0% to 100%. London (demographically the youngest part of the country) requires 90% of new homes to meet category 2 and the remaining 10% to meet category 3, but about half of authorities still require nothing more than the baseline. I assume this is partly because assessing need and viability is difficult and developers fight back if they try. The level of disparity makes it a postcode lottery, not an effective policy. It’s too complicated and it’s still very messy.

I was hopeful when the government launched a consultation on accessible housing last September. The tone of the introduction was remarkably positive. Four of the five rather nuanced options represented an improvement on the current situation; all but one proposing that category 2 becomes the new baseline. And quite right too. The demographic evidence is compelling: by 2050, one in four people will be over 65; only 11% of existing homes provide the four main features required for even the lowest level of accessibility, and 80% of today’s homes will still exist in 2050.

Having ignored the implications of rising life expectancy for so long, we have a huge amount of catching-up to do. The lockdowns have given all of us a glimpse of what, for many older and disabled people, is an everyday reality – because getting out is still difficult. Most homes have been tested and many haven’t scored well. Factor in age-related mobility problems and the shortcomings intensify.

The near certainty that over two centuries every home will be occupied by someone whose life would be transformed by an accessible home is justification enough

The need to reduce embodied carbon is another driver; every new home we build today should last at least 200 years. Over that period, we can assume that each will be home to something like 20 households and 70 individuals. Thousands of visitors will cross each threshold. These will be people of all ages, ethnicities and faiths. All will experience bouts of illness; the vast majority will grow old and most will use a mobility aid at some point. As we know only too well, their lives will change in ways they can and can’t predict.

几乎可以肯定的是，在两个多世纪后，每个家庭都会有人居住，他们的生活将因为一个无障碍的家而改变，这是足够合理的。但普遍应用的好处不止于此;我们也都想去拜访朋友和家人。这取决于我们知道，我们将能够通过前门，有尊严地使用厕所，并感到足够轻松地享受陪伴和场景的变化，这意味着很多，特别是对那些独自生活的人。The fact that a category 2 home benefits people of all ages, and disadvantages no one, clinches it.

The consultation on the changes to Part M was far from perfect. Regrettably, the best outcome – tying category 2 and the Nationally Described Space Standard (NDSS) together, was either not considered or rejected – crazy given that they were designed to be mutually supporting. Part M isn’t perfect either. The descriptions of each category are confusing, the guidance is poor in places (particularly category 3 bathrooms) and the adaptable features need to work for all forms of construction and tenures. It would make sense to fully install the shower required in the ground-floor toilet when using prefabricated pods and when building for rent, for example.

实施一直很差，需要做更多的工作，以确保那些将从一个可访问和可适应的家庭中受益最多的人了解他们提供了什么，以及在哪里可以找到它们。这有力地论证了当地可获取的住房登记和强制性标签在营销文献和租赁协议。

Unfortunately, the outcome of the consultation (which had originally been expected in March) is now due “by the end of the year”. There is talk of more research; not a bad thing, but likely to take years, and it’s worrying that the direction of travel hasn’t been confirmed. I remain hopeful, however. If we’ve learned nothing else over the last 18 months, it’s that dealing with the things we can predict will put us in a better place to deal with those that we can’t. Accessible housing has never been seen as a priority, and we need to change that.
