Think before extending

The Government’s announcement allowing extensions and conservatories to be built without planning permission raises many issues. Not least of these is the fact that an ill conceived extension could detract from the value of neighbouring properties if it’s not in keeping with the existing building, out of scale or of a low standard. With any extension, careful thought must be given to how it will work with the character and architectural rhythm of the original building, while being sustainable in its construction and future performance.

Even before considering an extension it’s worth taking a step back and asking whether it’s actually necessary. Might it be better to convert a loft space or basement or even create a separate room in the garden? These garden rooms are often available in kit form or can be built offsite and craned into position with minimal disruption – if you move, some have the benefit that you can take them with you.

If you do decide to go ahead with an extension plan it properly, keep it in proportion with the existing building and consider how the extra space and circulation areas will work. All too often I see an extension that’s simply been tacked onto the back of a house; this means that the room it’s been built off just becomes a corridor into the new part so little useful space is gained.

Maintaining natural light and ventilation to the existing house is crucial. The addition of an extension can result in rooms within the original building needing to be lit by artificial light or ventilated mechanically. This increases energy consumption and will devalue the ‘feel’ of the space and sense of wellbeing.

Remember that an extension is unlikely to be upgraded for many years so build it well and make it ‘green’ and energy efficient. Set out to achieve the highest levels of insulation and airtightness possible and use materials that are natural and local. If you’re adding it to an old building respect the original structure, wherever possible avoiding knocking holes in the walls and instead use existing window or door openings to access the new space from the old.

SPAB Working Party

For the last 25 years conservation experts and volunteer heritage enthusiasts have come together to join the annual Working Party run by the Society for the Protection of Ancient Buildings (SPAB). I went along to join them and created a video about the Working Party at Sullington Manor Farm near Storrington, West Sussex. They were working…

Listed building allure

Listed building allure

Every year, many of the estimated 450,000 listed buildings in the UK change hands on the property market. In England and Wales these properties are designated Grade I, Grade II* or Grade II having being deemed to be of historical, cultural or architectural interest. All buildings built before 1700

Environmental Pocketbook

Environmental Pocketbook

If you’re going to invest in just one book on sustainable, low carbon building I’d strongly suggest that you make it The Environmental Design Pocketbook. Now in its second edition, this useful volume by Sofie Pelsmakers should be essential reading for architects, designers, developers, planners, students, clients and anyone else involved in the construction and operation of buildings….

Fire in old buildings

Fire in old buildings

The devastating fire at the Grade I listed, 18th century National Trust mansion at Clandon Park, Surrey, once again highlights the need to do everything we can to protect old buildings. Whatever the size of the building, there are simple measures that can be taken to reduce the risk of fire, ensure early warning of a…

Adapting old buildings

Adapting old buildings

The need for fresh air and light in buildings is something I’m often talking and writing about because it’s central to creating a good home, but the theme is nothing new. I was reminded of this when I recently visited the King Edward VII Estate, near Midhurst, West Sussex. Here, the former sanatorium is being…

Building lime knowledge

Building lime knowledge

Lime, in the form of mortars, renders, plasters and paints, is a key component of old buildings and essential to their repair – or at least it should be. Today lime-based materials are also emerging into the mainstream and being used within low carbon construction systems, employed in everything from homes to superstores. All this…

Drain problems

Drain problems

A blocked drain is not a pleasant thing to wake up to. What’s worse is the realisation that it’s something that can generally be avoided by doing what I’m always talking about: maintenance. The drainage system is easily forgotten because much of it is hidden away underground but, as with any element of a building, it…

Building remembrance

Building remembrance

Visiting Blood Swept Lands and Seas of Red, the poppy installation at the Tower of London, reminded me that the built environment frequently plays an important part in both remembrance and memory. Each of the 888,246 ceramic poppies that flood the moat of the Tower depicts a death in the British forces in the First…

Materials testing

Materials testing

New techniques and materials aimed at producing low carbon solutions mean this is an exciting time to be involved with new build and retrofit. There are dangers though, in the rush to innovate there may be failures along the way so it’s vital that there’s scrupulously testing and monitoring at all stages. This is why…

Hidden London

Hidden London

Impending development often means there is a chance to step back in time because archaeological investigation may be undertaken as part of the work. This is especially true in London where layers of history have been laid down by successive generations as the city has evolved. Visiting Barratt London’s Landmark Place site close to the…

Renovation tale – Part 1

Renovation tale – Part 1

This is the tale of my first major renovation project some years ago… On the table is the surveyor’s report; yellow Post-it notes stick from its pages in such profusion that they no longer have any relevance. Phrases like “needs attention”, “must be thoroughly overhauled” and “a fair amount of dampness” are highlighted by marker… Continue Reading
