The details that decide it.

23 construction details ELS settles before fabrication — keyed by the problem they solve, not by style, and written from ELS's own coordination standard.

Guidance for planning, not a construction drawing — always confirm dimensions against your approved project drawings.

Junctions

Shadow gap at the floor, not a plinth

Problem: A pale carcass that sits directly on the floor shows the mop line — and it shows it at the eye level of someone seated, which is where people actually look.

ELS does: Lift the whole run and let a shadow gap, not a plinth, meet the floor.

Durability

Handleless grooves in a cooking zone

Problem: The finger groove of a handleless front collects cooking grease and dust. In humidity that becomes a permanent dark line across pale oak.

ELS does: Specify an aluminium profile pull rather than a groove routed into the board.

Dimensions & tolerances

Low contrast leaves nothing to hide behind

Problem: A 1 mm variation in a shadow gap that walnut would swallow is plainly visible on white and pale oak.

ELS does: Tighten the setting-out tolerance before the palette is signed off, not after the doors arrive.

Moisture & wet zones

Carcass base where cleaners wet-mop daily

Problem: Contract cleaners wet-mop daily. A timber skirting base wicks that water and swells.

ELS does: Stand every carcass on a sealed aluminium or stone plinth.

Services & M&E

Cable routes fixed at drawing stage

Problem: Grommets cut on site split the laminate edge, and the damage stays visible for the life of the desk.

ELS does: Fix cable routes for meeting tables and reception desks at carcass drawing stage.

Moisture & wet zones

Edge banding is the whole detail on a white door

Problem: A PVC glue line goes grey in a wet kitchen, and on a white door that line is the first thing anyone sees.

ELS does: Specify laser or PUR edging wherever humidity reaches.

Material behaviour

Tall doors need balanced construction

Problem: Entry-grade fronts arrive flat and go out of flat as the board takes up moisture.

ELS does: Specify balanced construction on any door over 900 mm tall.

Durability

Plated brass fails in coastal humid air

Problem: The lacquer lifts and the base metal blooms.

ELS does: Specify PVD champagne on stainless or anodised aluminium, brushed rather than polished.

Material behaviour

Gloss telegraphs substrate flatness

Problem: Any sheen above satin reveals every imperfection in the panel beneath it, and grazing light makes it unmissable.

ELS does: Put sheen above satin only on balanced-construction panel, and never where light grazes along the run.

Material behaviour

Cream is a match, not a colour name

Problem: The lacquer door, the quartz top and the wall paint will not agree across three suppliers — each reads 'cream' differently.

ELS does: Nominate one master sample and match every trade to it.

Material behaviour

Declare one grain direction per run

Problem: Adjacent doors read as different products once side-lit, even from the same batch.

ELS does: Declare one grain direction across a run, and keep one batch across a single visual field.

Services & M&E

Every enclosed meeting room needs one absorbent plane

Problem: Dark stone, glass partitions and plasterboard form an acoustically hard box, and video calls clip.

ELS does: Give every enclosed meeting room at least one absorbent plane.

Junctions

Curtain pocket in a coffered ceiling

Problem: A curtain track screwed under a finished ceiling is visible, collects dust on its face, and leaves no room for an LED wash — so the ceiling and the window never read as one designed plane.

ELS does: Form a curtain pocket into the coffered ceiling, sized at construction stage, with the LED recess and thermal access coordinated into the same detail.

Junctions

Internal corners in a panelled wall

Problem: A mitred internal corner in veneer opens up as the panels move, and once it opens there is no way to replace one panel without disturbing its neighbour.

ELS does: Use a controlled butt or reveal at the internal corner rather than a mitre, and detail it so a single panel can be replaced.

Moisture & wet zones

Veneered window sill corners against condensation

Problem: A timber-veneered sill turns an external corner right where condensation collects, and any concealed timber edge left unsealed there swells and lifts the veneer.

ELS does: Seal every concealed timber edge at the sill corner and detail a moisture separation, confirming the overhang and joint sequence before fabrication.

Material behaviour

One declared grain direction across a run

Problem: Run a timber front with the grain going whichever way each door was cut, and the moment the run is side-lit the adjacent doors read as different products.

ELS does: Declare one grain direction for the whole run before production, and match every leaf to it.

Durability

Textured, not smooth, matte black in a kitchen

Problem: Smooth matte-black hardware shows every fingerprint in a humid kitchen, and the marks return minutes after they are wiped.

ELS does: Specify a textured matte black rather than a smooth one wherever hands land — pulls, taps, the frame of a glass door.

Material behaviour

Cream is a match, not a colour name

Problem: The lacquer door, the quartz top and the wall paint come from three suppliers, and their 'cream' will not agree — the mismatch shows up only once they are installed side by side.

ELS does: Nominate one master sample and approve every other cream against it on site, under the site's own lighting, before anything is ordered.

Material behaviour

Gloss telegraphs a flat panel's every wave

Problem: Any sheen above satin on an unbalanced panel shows the substrate's waves, and they appear at eye level on site — not in the workshop where the panel lay flat.

ELS does: Put any gloss on a balanced-construction panel, and never place a glossy face where light grazes along it.

Durability

PVD champagne, never plated brass, near the coast

Problem: Plated brass fails in coastal humid air — the lacquer lifts and the base metal blooms — and gold-toned hardware holds fingerprints longer than any other finish.

ELS does: Specify PVD champagne on stainless steel or anodised aluminium, brushed rather than polished.

Services & M&E

Concealed LED channel: confirm the profile before the ceiling closes

Problem: A cove or concealed LED line is drawn as a simple line on the ceiling plan, but the channel that holds the strip has its own profile dimensions and installation method. When the recess is built first and the channel is chosen afterwards, the recess may not suit the channel, and the driver can end up sealed in.

ELS does: Confirm the channel before the construction detail is frozen: its profile dimensions, how it is installed, what it is fixed to, and where the driver is reached. The recess and the plaster and ceiling sequence are then drawn around that channel, and the driver is given a reachable bay or hatch on the reflected ceiling plan.

Junctions

Floor transition: a flat join or a proper step, not a small in-between

Problem: Where one floor meets another, between old extensions or between two floor materials, a small unplanned level change trips people and traps water at the join.

ELS does: Decide the transition before the floors are laid: keep one flat level and let the change of material mark the zone, or make the level change a proper step of 150 mm or more, or plan a ramp or a detailed threshold. The profile that finishes the join, its dimensions and how it is fixed are confirmed before the flooring is specified.

Moisture & wet zones

Bathroom floor trap and waterproofing: choose the trap before the grate

Problem: A floor trap chosen by the look of its grate can turn out too deep, restrict flow, conflict with the slab or sit above the required floor gradient, and the waterproofing around it can fall between the plumber, the tiler and the main contractor.

ELS does: Choose in this sequence: drainage location, pipe diameter and depth, required flow, anti-odour or backflow function, the waterproofing interface, tile thickness and gradient, and only then the visible grate. Match the trap to its use (shower, general floor, washing machine or backflow risk) and record its outlet size, direction, installation depth, flow capacity, removable hair strainer and anti-odour mechanism; any figure not yet known is set per project. List waterproofing as its own package.
