Single aspect flats

February 9th, 2010

UPDATE: 7/4/17 Now these dreadful things at Barnet House

Here’s the Guardian take on it:-

“no better than back to back terraces”

One of my bugbears as a layman taking an interest in housing is the number of modern conversions that take a former office building, usually rectangular, and convert it into flats in the cheapest possible way by putting a corridor along the centre of each floor and apartments off each side like hotel rooms.  Access is via lift and stairs at either end and results in what the Americans call double loaded corridors.  The flats are then by design single aspect and sometimes North facing.  Inevitably the others are South facing and suffer solar gain to the same extent that the former almost never see the sun.  I found the following article on the Internet recently whilst looking for Parker Morris links.

The current Part L of the Building Regulations focuses more on heat loss through windows than light levels into a house. Regulations allow us to get away with deep plan single aspect apartments, in my mind no better than back to back terraces, or windowless bathrooms, kitchens and corridors, despite the fact that everyone knows these spaces would be better with natural light and ventilation. House builders generally do the minimum required of them by the regulations, which is not necessarily what makes for good housing. Sustainability is more than just environmental performance.

The idea of rooms lit only from one side with no through ventilation and intended not as an overnight stay as with a hotel room, nor as temporary student accommodation as in halls of residence, but as a family dwelling is to me entirely unsatisfactory. They make a frequent appearance in the projects of the social housing company A2Dominion with Woods House being but one example and I feel unsettled that it should be the most vulnerable in society that have poor standards of design imposed upon them for it is those with least assets who have no other choice.  Note the concrete columns at the perimeter of the plan which further compromise the design.  It may be nice to live in Pimlico but not at any price.

Not suprisingly there are developers who balk  at the idea of providing dual aspect flats.  Here’s this from the AJ

Dale Sinclair, director at Dyer, questioned the report’s prejudiced criticism of single-aspect flats: ‘Dual-aspect units require additional stairs, lifts and external walls or an increase in deck access. With developers unable to offset risk, will this also increase costs?’

UPDATE: I was in Glasgow this week (w/e 11th June 2011) and went to see where Dale Sinclair lives.  It can’t be his only house.  It is a small single aspect house built into the side of the hill on which stands Park Terrace and Park Circus.  I am left wondering whether the experience of doing up and living in (or at least occasionally staying in) a former mews house has informed the views expressed above about single aspect flats.

UPDATE: Please see my page on back-to-backs taken from the Housing Act 1909.

I found this today (5/7/2010) an article from Building Magazine by David Birkbeck that gives hope for the elimination of single aspect flats, and mentions Alice Coleman in passing. See also Design Disadvantagement

How you manage movement to and from apartments is tearing the industry apart at the moment. A proposal in the London Housing Design Guide threatens to outlaw single-aspect flats, the default setting for apartment blocks built in the past decade. The guide also recommends a maximum number of homes per floor that can share the same access.

From Sean Macintosh:-

Rooms can be either naturally ventilated or mechanically ventilated (by fan or other system). Under current regs toilets are required to have a fan even if they also have a window. A dual aspect flat can benefit from cross ventilation and this means that you can have a much deeper plan. There is nothing preventing single aspect flats ventilating effectively as long as there is sufficient window area (ideally both low and high level) and that this is proportional to the floor area and occupancy. Nowadays we measure this through computer analysis.

Dave Hill of the Guardian has alluded to these in new developments, citing the ones planned for Earls Court:-

Of the 690 total, 287 units would be “single aspect” dwellings, meaning that light can only enter them from one side. Single aspect dwellings are controversial. As the council officers’ report notes (see page 188), they are “generally discouraged by both local planning policy and the [Boris Johnson] London Plan”. The report further records that the council’s own planning rules state that single aspect units which face north are particularly frowned on – they “should be avoided wherever possible”. Yet 103 of Capco’s 287 single aspect units – 15% of the 690 total within H&F – would be north-facing.

Good reason to reject the plans? The officers’ report thinks not. It assures us that north-facing single aspect units have been “avoided where possible”. It says that most of the north-facers are within two of the eight buildings proposed and that, of these, “almost” all the ones that “infringe the council’s standard” would only do so by a few degrees and, anyway, their windows are quite large. Does this conform to the “decent neighbourhoods” requirement for good design?

One Response to “Single aspect flats”

    Oh my goodness! I’ve just happened upon this blog, having searched the web for single-aspect flats.
    I’m currently living in a double-aspect council flat (H&F), with communal balcony. However, I now live alone in a 2-bed flat (underoccupancy) and am expected to accept the offer a one-bed, single-aspect flat in an internal corridor block. I’m dreading it and the possible claustrophobic feelings I may experience.
    The beauty of where I am at the moment is the light and the air that flows through the flat when all the windows are opened. And, in summer, many residents leave their front doors open to let in more air. It’s a very friendly thing to do. The place I’m expected to move to has only the internal corridor and no balconies. Where am I to hang my washing? Will I see my neighbours. I detest the thought of living there, but have no choice. It’s a rubbish way to treat a very long-term and non-troublesome tenant.
