= Introduction =&lt;br /&gt;
&lt;br /&gt;
An intimate knowledge of the fabric of a historic building – its condition and history – forms the foundation of any future change or restoration proposals. Any architect, engineer, surveyor or estate manager engaged in prolonging the viability of a historic building – or indeed a whole conservation area – must at some point get to grips with this most basic of approaches.&lt;br /&gt;
&lt;br /&gt;
To achieve this level of knowledge requires accumulating three levels of knowledge:&lt;br /&gt;
&lt;br /&gt;
* The building as found&lt;br /&gt;
* Group context&lt;br /&gt;
* Learning from historic and contemporary texts.&lt;br /&gt;
&lt;br /&gt;
= The building =&lt;br /&gt;
&lt;br /&gt;
The building is usually the prime source of knowledge which can be accessed through a physical investigation of its fabric. As one of the best ways of getting to know the physical characteristics of a building, it will typically involve at least a measured survey of the architecture and structure, relying on astute personal observation and basic sketching ability. I&lt;br /&gt;
&lt;br /&gt;
This process can be supplemented by technological aids, including photography, photogrammetry and computer-aided drafting and, if necessary, recourse to carrying out documentary research. The benefits of such a process is that the conservator gets to know every inch of the building, including its details and idiosyncrasies, and from there can start to understand the character.&lt;br /&gt;
&lt;br /&gt;
Critical tools to this process are the sketchbook and the camera. Although not generally regarded as substitutes for one another, they are usually complementary and used in combination can be highly effective: the camera can record details which a sketch made on site may miss. Furthermore, scrutinising a photograph back in the office may reveal facts about the building which may not have been known about beforehand.&lt;br /&gt;
&lt;br /&gt;
However, an accurate sketch can record details which might not be apparent on photographs and can also zoom-in on particular aspects of details which a camera might not be able to do. Both sketching and photography therefore are highly useful aids for the conservator.&lt;br /&gt;
&lt;br /&gt;
= Group context =&lt;br /&gt;
&lt;br /&gt;
A proper understanding of a historic building usually requires an appreciation of the building’s context. But to interpret the information gleaned on site requires a framework of sometimes specialist knowledge on the part of the conservator, including an understanding of how buildings were constructed during the period that is under consideration. It is frequently necessary to be acquainted with the locality’s history covering aspects such as building typologies, plan forms, structures, materials, joinery techniques and mouldings. Armed with such knowledge, conservators will be able to recognise occurrences of these features and so avoid accidentally destroying them. Also, it can enable them to appreciate whether a major fault is particular to the building or whether the technique which caused it was common practice at the time of construction, and is seen on other similar buildings – which have stood the test of time.&lt;br /&gt;
&lt;br /&gt;
The historic environment provides continuity with the past, but also accommodates change and helps places adapt to the present and future. In any intervention, it is important to understand why such buildings have lasted as long as they have, sometimes over centuries, and the deleterious effect that modern materials and techniques could have if applied insensitively. For example, introducing hard, inflexible materials into an otherwise soft and flexible environment could be disastrous. This is especially pertinent when an old building has to be adapted to a new use for which it was not designed, for example, adapting an old mill to serve as the offices of a small company.&lt;br /&gt;
&lt;br /&gt;
Historic and contemporary texts&lt;br /&gt;
&lt;br /&gt;
Referring to earlier books that give an understanding of what the builders and architects were trying to achieve can significantly boost the conservator’s background knowledge. Also, contemporary manuals authored by acknowledged specialists can be useful.&lt;br /&gt;
