A rendered elevation of a living room wall tells everyone what the shelving is supposed to look like. It does not tell a factory what to build. The gap between the picture and the price is where modular projects stall, and it is the gap this guide closes. If your brief already shows metal-frame modular shelving - or a wall system that will need one - here is how to package that brief so the quotation you get back is the one you can actually approve.

Why modular wall systems break the normal RFQ process

Built-in joinery arrives as a fixed set of dimensions: a standard wardrobe comes to you as width, height and depth, one carcass, one price line. A modular shelving system behaves differently. The run length, the vertical division points, the mix of open shelf, drawer and closed-front modules, the finish of each panel, and whether lighting is wired into the frame are all specified per project, with made-to-measure dimensions and selectable materials and finishes. That is the point of a configurable system, and it is also why a single-line enquiry invites a single, useless number.

The Santerson Metal Frame Modular Systems range sits in exactly this situation: shelving for residential wall system projects, where layout, finish and dimensions are set to suit each space. The same applies across the wider shelving collections, from Santerson Floor to Ceiling Systems to Santerson Integrated Lighting Systems. A workable enquiry describes the run, not the picture.

Step 1: convert the intent behind the brief into module types

Start by reading your own brief for what it wants the wall to do, then translate each requirement into a module type. A designer's note reading "display and storage, living room, continuous with media unit" is really four decisions: open display bays for objects, closed fronts to hide clutter, a media bay at a fixed centre distance, and a base run that carries the load. Write those decisions down as a list, one item per line. If you have chosen open fronts throughout, note that too - our Metal Frame Open Wardrobes use the same logic in a bedroom, where the visible frame is part of the design rather than something to be closed off.

Send the list, not just the render. A list is what lets a manufacturer price, and where something is missing, ask about it.

Step 2: send the measurements that survive on site

Three sets of numbers decide whether a wall system fits, and design briefs usually carry only one of them.

• Overall run: total length, height and depth of the wall, taken at the finished surface, including skirting, architraves and any recess the system has to return into.
• Fixed points: the position of switches, sockets, radiators, downlights, structural columns, doors and windows - measured from a common datum, the same corner for every dimension.
• Interfaces: what the system abuts - stone hearth, plasterboard, tiled wall, timber floor, and whether the wall can take a load-bearing frame fix.

Flag every number that is not yet final, for example where a floor finish is still to be laid. A manufacturer who knows a dimension is provisional can allow for it; one who does not will build to it.

Step 3: name the finishes rather than pointing at a picture

A mood board reference such as "warm oak, soft black frame" cannot be quoted. Convert it into a finish specification: the panel material, the surface, the colour or decor reference, and the frame profile and colour. Where the brief specifies a match with other joinery in the project - kitchen fronts, wardrobe doors, a media wall - say so explicitly and identify the product the finish has to match, since the same frame language runs across our built-in ranges. Confirm the selected specification in writing at quotation stage; a colour shown on screen and the surface produced are not the same thing, particularly for veneers and metallic or high-gloss lacquers.

Step 4: state what has to be resolved before production, not after

Two categories of decision are routinely left too late on modular wall systems, and both are visible in a brief if you look for them.

The first is loading. A bay holding books and a bay holding a television carry very different weights, and shelving depth, span and support should be confirmed for each of them rather than assumed across the whole run. The second is electricity. If the design calls for lit shelves or an illuminated display bay, the wiring route, driver position, switch point and low-voltage supply need to be settled before the frame is built, not chased into it afterwards. Lighting integrated into shelving is a product decision on our side and a first-fix decision on yours, so it belongs in the enquiry.

Step 5: ask for the quotation in a form you can compare

Whatever else you do, ask for the answer as a module-by-module schedule with a line for each run: elevation reference, module type, dimensions, finish, hardware, lighting, and price. That format does two things. It shows you where a designer's intent has been quietly substituted, and it lets you compare two quotations against the same scope instead of against two different guesses.

Because we manufacture to project drawings under a custom and OEM service - design and prototyping, material and finish selection, then production coordination - the same enquiry also carries forward into production without being rewritten. The brief you send at the start is the brief we work from; the job is to make it specific enough to be built from.

If you have a wall system in mind, send the render with the module list, the three sets of measurements and the finish references, and we will come back with a schedule you can sign off.
