When you have found a decent-looking plan, it can be easy to think that now building time is here. In fact, builders require an accurate and detailed specification to price the job correctly and build it safely. The specific drawings will depend on your project, but again the generalities are usually pretty similar in particular builds.
1) Existing and proposed plans
Typically you will require existing drawings (what is there currently) as well as proposed drawings (what change you want to make). They detail layouts, the size of rooms, doors and windows etc. as well how the space will flow from one area to another.
2) Elevations and sections
Elevations are illustrations of what the exterior will look like (front, back, sides). Sections are called “cut-throughs,” showing heights, floor levels and roof shapes along with how the new meets existing. For a Monmouth Architect, contact Hills & Co, a leading Monmouth Architect.
3) Planning drawings (if required)
The drawings are for planning and if your project requires planning permission you will need a set of suitable drawings. They are about the looks and dimensions, NOT every construction detail.
4) Technical Drawings/Building Regulations
For construction, you typically need technical drawings which satisfy building regulations. These include construction detail (insulation, drainage, ventilation etc) so that there is less guesswork on-site and they are more site-specific.
5) Structural information
Take beam calculations and drawings from a structural engineer (beams, lintels and foundations/load paths) if you are removing walls or incorporating openings in your house such as an extension/loft conversion.
6) A specification (often overlooked)
Written specifications, defining materials and finishes included. The variation can be huge without it.
Simple rule
For realistic quotes and less surprises, do not start with a “sketch”. Begin with diagrams that simply illustrate what is being created.
