latest feedback from EW on 12nd Nov, below are the partial reply extracted from the email with updated recommendation list
Lastly, the process of studying, choosing and incorporating new products is not an easy feat and will require some time - no one will appreciate a hastily done job. However, we shall endeavour to make the above changes the soonest possible.

From our side, we sincerely hope this will help put your mind at ease.
recommendation list updated, 23rd Dec 2015

1.) Improve the outdoor compartments: letter box/3r box/utility box
The outdoor compartments need to be improved with quality hardware and design to match the premium product. The compartments give the impression that it is a replica from a low cost flat. In addition, the letter box is probably too big and consumes a lot of space.
[Purchaser Team]: 30% improved, need further shrink at compartments' sizing and eliminate the gap that is found between 1 compartment with neighbor's compartment, in order to improve car porch spacing and to match ES modern facade.
[Eco World]: The refuse chamber compartment size cannot be reduced as it is governed by authority requirements. While eliminating the gap between two compartments will improve car porch area, it will make the refuse chamber compartment look very bulky (double the current size). This was studied during initial planning stage.
[Purchaser Team]: We guess nothing much we can do as sizing is the appointed standard. However we still felt that the gap is sort of space wasting, hope EW can really think twice for enhancement.
2.)Improve the staircase handrail (stainless steel and glass ??)
The handrail, whilst it is acceptable, is not the best to match the price tag of the houses. The handrails can be enhanced further by expanding the wood handrail by a few cm wider. A point to note is that the type A handrail does not match the premium product standard.
Suggestion: For all the unit types, please honour the stainless steel and glass handrail as PROMISED during sales launch
[Eco World]: Glass railing will only come standard in the Type A super link unit and Bungalow. We will study with architect on how we can improve the existing handrail detail of other units e.g. stability.
[Purchaser Team]: Noted for stability issue. We assume handrail design will get enhanced too. Please advise if those enhancement will be done for show houses, if yes, when ?
[EcoWorld] : Regarding handrail stability, our technical team believes that the original handrail is sturdy enough for a home. Having said that, since stability is one of your primary concerns, we will be engaging our architects to study how we can further enhance the stability by adding on additional members to anchor to the floor without compromising the design at the actual parcels.
3.) Enhance the design and safety of the staircases
The design of the staircases does not match with the premium product standard. In addition, even if assuming the staircase is the bungalow type, there is a potential safety risk as there are holes between each staircase steps.
[Purchaser Team]: There is also instability of 1st floor handrail, applied for unit with double volume.
[Eco World]: Handrail stability will be enhanced for types that have been highlighted.
[Purchaser Team]: Noted.
4.) Improve the colour coordination of the timber strip
The colour for the timber strip does not match with the interior/exterior design of the tiles/door provided. We propose the usage of light-coloured strips as opposed to the dark coloured strips. Dark-colored strips denote a more business-look and more suited for car showroom/restaurant. Reference can be made to the EM light-coloured timber strips used at the show house units.
[Eco World]: Walnut colour will be maintained however lighter shading will be considered.
[Purchaser Team]: Noted, please advise if enhancement will be done in show houses, if yes, when ?
5.) Unmatched quality of sanitary ware
We were made to understand that the minimum brand promised were Bravat and Johnson Suisse. The show units seem to have been installed with Serecite (by Inno). Is this the final product?
[Eco World]: Current brand maintained.
[Purchaser Team]: Based on real experience, flushing for Serecite is not strong enough, a few times of flushing are needed in order to flush away the ‘business’, we have been told by EW that used of Serecite was due to its comfort-ness, we hope functionality is within EW’s consideration as well.
6.)Unmatched tiles used in sink
The tiles used in the sink do not match with the sanitary ware.
[Purchaser Team]: Type of tiles that used for sink area is flooring tiles.
[Eco World]: Will improve the appearance of the counter top tiles based on architect proposal.
[Purchaser Team]: Please advise if enhancement will be done in show houses, if yes, when ?
7.) Question mark on quality of room doors
The show units seem to be equipped with cheap 'timber' doors in every rooms. Is this the final product?
[Eco World]: Current show village did not install room doors. Room doors will be Honeycell timber doors.
[Purchaser Team]: Noted, concern raised was due to entrance door used for guest room in Hermosa and backyard’s door.
[EcoWorld] : We shall address your concern for a more solid door at the back yards and the guest room (Hermosa).
8.) Improve the quality of backyard grill/door
Cheap steel and door knob seems to have been used, unmatched with a premium product paid by customers.
[Eco World]: Steel grille at back yard are made of large steel sections that are sturdy (safety). Door knobs at yard will be studied as to how to improve it.
[Purchaser Team]: Please advise if enhancement will be done in show houses, if yes, when ?
[EcoWorld] : As for the backyard door knob, we have noted your preference of having an improved door knob. We will explore different options and update the lockset at the show house in the near future.
[Purchaser]: Door knob gets revised in each show unit, case closed.
9.) Standardize the bathroom drainage hole
The bathroom drainage hole is not standardize. Bathroom is divided into 2 by shower screen. Please ensure there are drainage holes in both sides
[Purchaser Team]: Shower screen height need to be increased to prevent water spills, bathtub height to be studied and improvement if possible.
[Eco World]: Bathrooms divided by shower screen shall have 2 floor traps. One at each space. Bath Tub height will be studied.
[Purchaser Team]: Please advise if bath tub height will be tuned in show houses, if yes, when ?
10.) Upgrade the wall switches
The wall switches need to be upgraded to a better looking type. Need not have to be as nice as the one used in bungalow but definitely not the one used in Terraza or even the semi-D.
[Eco World]: The switches used at our units are Legrand brand form France. It is equivalent (if not better) to other comparable brands such as Schneider (formerly Clipsal from France). Legrand was used for its better design and ‘soft press’ mechanism that gives a higher end feel.
[Purchaser Team, 9th Nov]: We don’t think switches used in current show houses are branded from France, it looks more like low cost switches.

[Purchaser, 23rd Dec]: Wall switches got swapped with brand visibility in each show units. Case closed.
11.) Improve the workmanship
The workmanship in the show houses leaves much to be desired.
Example : scratchessss on timber grip, uneven tiles, gap between tiles, painting, etc..
[Eco World]: Noted, only CONQUAS certified contractors are allowed to tender for EW projects.
[Purchaser Team]: Noted.
12.) Regio facade painting
Initial scale model and video were showing white in color facade, however show house for Regio is in Greenish Dark.
Suggestion: White color is preferred.
[Eco World]: Colour tone shall be similar as show house.
[Purchaser Team]: Noted.
