The technical drawings are the product of the previous design stages. They are key to implementing a good design and getting a firm costing from your contractors. This stage of the interior design is also usually the most time consuming.
During this stage we develop the design of your shop or restaurant interior that has been agreed in the concept stage. Whilst we fine-tune the design we also need to produce something that clients and builders will easily understand. We usually divide the drawings into three segments: plans, sections and general details. If required, we can also produce more schedules.
General layout plan
The plans will show the general layout (normally covered in the concept design stage) as well as the following:
Reflected ceiling plan
The best way to describe the reflected ceiling plan is to imagine slicing the interior space at about 300mm below the ceiling level. You then draw the plan looking up, but because if you did this the plan would be a mirror image of the general layout plan you reflect it. This gives you a reflected ceiling plan. Here we can show the size and shape of any ceiling features, and most importantly, the lighting layout. We can also include information like smoke detectors and emergency light positions, although emergency equipment plans or licensing plans will often do this.
Wall and floor finishes plan
This plan is simpler to explain. It shows the floor finishes using hatches and patterns, and puts a specification next to them.We sometimes put the wall finishes information on the plan, but often the sections cover this more effectively. It can be useful to show the floor levels on the drawings as we may need to build up some areas in order to make things flush. Sometimes with wall finishes it’s only necessary to stipulate the type of wall finish on the plans so that they can be accurately costed. The client will then agree the exact product on site once they have tried out sample areas.
Small power plan
The small power plan contains all the information regarding electrics, power and phone / data sockets. We usually work this in conjunction with the client as it’s one of the operator’s key plans, and the client may have a need for occasional items that will require some form of power at another point during the year.
Setting out plan
The contractor usually eagerly anticipates this plan as it sets out the dimensions for the retail or restaurant interior. It is important that all parties understand that the setting out plan is an intent rather than a definitive set of rules. For several reasons surveys can be a little out, or walls may have been lined in a slightly different way than originally planned. For this reason we will put certain measurements down as being site dimensions or equal.
We at Engaging Interiors love a good section. We sometimes work them up during the concept stage as they are a very useful way of explaining how the wall of a restaurant or retail interior will be lined. Using a simple line drawing format or colours, the sections explain where different wall finishes start and end. They can also act as a directory for other detailed drawings of the interior.
