The CABE Experiment and housing design: where have all the leaders gone?

Bad design? Housing development in Melton Mowbray by Persimmon

Guest blog: Matthew Carmona and Lucy Natarajan

Here at The Bartlett, UCL we recently completed a major study of the eleven years of publically funded CABE, the Commission for Architecture and the Built Environment. We evaluated the work, history, and impact of the organisation, and the ‘tools’ it used to promote good urban design across England. When it came to housing design CABE had real impact and, as we argue here, the leadership it provided is sorely missed. But there are ways that planners, urban designers and the government can draw on the CABE Experiment, which will be increasingly important in light of the intended increase in the volumes of housing being built.

CABE was never well understood. External perceptions were often of a monolith swallowing up huge dollops of tax-payers’ money to conduct design review. As we reported in our book Design Governance: The CABE Experiment, the organisation was tiny by government quango standards, and only around a fifth of its staff were dedicated to design review. The rest of the staff worked on lower profile but typically highly regarded and effective activities such as: enabling within local authorities; its research projects; the work of its public spaces and parks arm (CABE Space); production of its very well used guidance and website; and various educational enterprises such as its summer schools.

These ‘informal tools’ of CABE were not mandatory or statutory and instead influenced and guided the professions. Yet they created a culture that improved design, for housing as for many other aspects of place. The work of CABE even reached some, although not all, of the volume house builders. Such progress will easily ebb away without continued efforts and leadership.

But how did improvement happen?

The answer is relatively simple: CABE’s tools were flexible and the activity was coordinated across the country, with the voice of government behind them. CABE addressed the issue of housing design from different angles, with:

  • national housing audits to embarrass the housebuilders with a stark national picture of the generally poor standards of their products
  • case studies and guidance to demonstrate principles and help raise aspirations
  • training for local authority staff
  • ‘enablers’ within local planning authorities working directly with councils, assisting with policy frameworks and large-scale applications
  • hundreds of design reviews were conducted on residential-led masterplans around the country

In addition, the Building for Life consortium helped establish nationally acceptable standards and an awards system for the best housing designs. And last but by no means least, government strengthened national policy, including on highways design in residential areas.

So where are we now?

Since CABE’s demise we have seen a large scale withdrawal of government, at national and local levels from engaging in design, and a fragmentation of the non-governmental design governance services that remain.  We have also seen a retrenchment of house builders, highways authorities, and planning authorities across the country back to the old ways of doing things.  Respectively, these are based on standard (and inappropriate) housing types, rigid and over-engineered highways standards, and planning authorities without the time, skills or confidence to challenge the house builders.

This is not to imply that nothing is happening. The Place Alliance provides a forum for ‘grassroots’ exchange and, bubbling up from these connections, UDL initiated and lead the work to produce a collaborative and comprehensive guide: The Design Companion Planning & Placemaking. This publication demystifies the principles behind ‘good places’ and explains with detailed examples how planners and placemakers can deliver the highest standards in urban design. In addition the largest metropolises particularly benefit from local leadership, particularly the Mayoral SPG for new build in London and Manchester’s City Council’s guide. However without the national coordination of such initiatives, housebuilders can and surely will cherry pick where they build quality homes.

But learning the lessons from the CABE era…

What should the government do now?

  • Show leadership: Minsters should speak out when residential design is poor and celebrate it when it is not, and appeal decisions where residential schemes were rejected on design grounds can provide rich illustrations for that work.
  • Support proactivity in local authorities: LAs can move away from reliance on generic policies in local plans and prepare simple non-statutory site-specific frameworks and design codes for housing sites.
  • Promote design review: This constructive peer-based checking and refinement mechanism should be made compulsory in the forthcoming revised National Planning Policy Framework (NPPF) for all major housing schemes.

Speaking up for better places and better homes will help those who are working on the ground, and as Design Governance: The CABE Experiment shows, this can have a great effect.  With little cost and no new legislation we can once again drive design quality up the national agenda.

New ideas for housing in London

Houses-on-coins-by-Images-Money

2015 was the year London’s population reached 8.6 million, a peak figure last reached in 1939. The capital’s population is set to rise by a further 1.6 million over the next 20 years, and by 2050 may have reached 11 million, more than the current combined populations of Scotland, Wales and Northern Ireland.

The rising numbers will add exacerbate the shortage of housing in the capital, which the head of the London Housing Commission has described as “one of the biggest public policy failures of the last 50 years.”

A showcase for new ideas
A major exhibition highlighting new thinking on solving London’s housing crisis is currently taking place. Organised by New London Architects (NLA), “New Ideas for Housing” highlights more than 100 ways in which London’s shortage of housing might be addressed.

Ten of the 100 shortlisted ideas were selected as winning entries from a competition that attracted ideas from architects, contractors, manufacturers, economists and house builders.

Among the winners were:

The Urban Darning Project
Employing the sewing technique for repairing holes or worn areas in fabric, the project aims to encourage small residential developments in central London to ‘fill-in the gaps’ of the urban fabric.

Supurbia
This idea has twofold approach: redeveloping local main streets and parades as mixed-use places with increased housing and amenity provision; and allowing owner-occupiers of semi-detached homes to develop their land, creating rich diversities of housing.

Investing in London’s Future by Learning from its Past
Drawing on London’s former leasehold system, this idea suggests that separating the cost of housing as a physical product from land costs would make it more affordable to build and buy houses.

MegaPlan for a MegaCity
The originators of this idea suggest that in order to meet the shortfall in housing by 2050, less than 4% of ‘edge land’ (the inner belt running from the inner London Green Belt to the M25) would need to be released from the Green Belt.

Wood Blocks
This idea proposes scaling up the growing appetite for self-build homes. A structural, weatherproof, thermally- and acoustically-insulated shell would be built by a developer / housebuilder, which could then be partitioned and fitted-out by new owners, delivering faster and cheaper housing.

The ideas are described in greater detail in a publication accompanying the exhibition. The NLA Insight Study also examines the current state of play in London’s housing supply, addressing the barriers around planning, land, funding, construction, procurement and design.


New Ideas for Housing
Exhibition dates: Thursday 15 October – Thursday 17 December 2015. Opening time: Monday to Friday: 9.30 am – 6.00 pm; Saturday: 10.00 am – 5.00 pm.
Address: NLA, The Building Centre, 26 Store Street, London WC1E 7BT

By James Carson

Earlier this year, we looked at a style of building known as Passivhaus, which is playing an important role in creating energy-efficient homes. Now, another concept – the Aktivhaus – is taking this approach even further, graduating from energy-saving to energy-generating homes.

The Aktivhaus concept

Like Passivhaus, the Aktivhaus has its origins in Germany. Stuttgart-based architect Werner Sobek defines Aktivhaus buildings as those which:

  • offset their annual total energy consumption in a sustainable manner;
  • anticipate and react accordingly to relevant changes both inside and outside the house;
  • continuously measure and optimise all energy streams.

Sobek’s idea has been realised in the form of a building called B10. This prototype Aktivhaus – prefabricated offsite and assembled in a single day – is located at the Weissenhof settlement in Stuttgart. It’s an appropriate site for applying a revolutionary concept – in 1927 the Weissenhof estate hosted a housing exhibition that included designs by leading lights in modern architecture, such as Le Corbusier and Ludwig Mies van der Rohe.

The Aktivhaus enacted

On the face of it, B10 is an 85 square-metre box with a full-length window. But its sophisticated design means the Aktivhaus can generate twice as much electric power from sustainable energy sources as it consumes. This means it can not only satisfy its own electricity needs, but can also power two electric cars and a neighbouring house built by Le Corbusier for the 1927 exhibition.

The ‘active’ element in the Aktivhaus is a mini computer, connected to the internet, that monitors weather forecasts and enables the house to respond accordingly, with different rooms heated or cooled at different times of the day. Other elements include a highly efficient heating system, web app-operated functions to control lighting and window blinds, and 17mm thick vacuum glazing whose three layers keep heat in and draughts out.

Werner Sobek believes that the Aktivhaus concept is not only applicable to new homes. “Our system is very helpful for old buildings,” he told the New York Times.

Some might feel it best to leave the imperfections as they are and not invest in major energy improvements and instead rely on the surplus energy from a ‘sister house,’ but the system can also help you decide to make modest changes to the windows or to improve the boiler.”

Over three years, researchers will study B10’s performance as a real-life residence. The building can later be dismantled and reassembled elsewhere, and when it reaches the end of its life almost all parts of the Aktivhaus have been designed to be recycled.

With construction costs of €100,000 and the technology inside priced at a further €600,000, the Aktivhaus is hardly an affordable housing option. But eventual scaling up of production could drive those costs down.

In the meantime, the ideas coming out of the Aktivhaus project may influence those looking for ways to tackle the ongoing issues of housing shortages, climate change and fuel poverty.
