How to Calculate Cost for Interior Design Work at your own

Welcome back home owners, hope you have read the previous article of planning theinterior design work at your home. Now comes the budgeting the basic costing for all over interior work. With the help of this blog, we will make you understand the techniques in estimation of the cost for home interior execution. If we categorize the whole work in different section we will get:

A.    Carpentry Working- Carpentry includes fixed furniture like Wardrobes with all fittings, LCD Panels, Showcase, crockery stands, cabinets in washrooms, door lamination, paneling on walls etc.

B.    Modular Kitchen- Although this also a part of wood work, but treated as specially, because modular kitchen requires extra attention in selecting a combination laminates, ply boards, hardware fittings as per your need, channels, soft closes etc. There are variety of range available in market like ozone, Godrej, hettich, Kaif with some Indian brands like zinc plus, sleek and many more.

C.   False ceiling- Commonly there are two type of false ceiling work one is gypsum board based and other is pop base. In residential we suggest to go for pop based false ceiling to have perfect finish. Design you can freeze with you interior designer. If your designer is decorator then it is best. So try to choose interior designer and decorators only.

D.   Painting Work – As per your developed interior designs the designer will give you colour codes of used shades. You can check actual feel of colors in shade cards of companies like Asian paints,, Narolac, Dulex, Berger. After chooing the shade you need to discuss the process of painting on walls. Like how much cote he will be doing, will he apply wall putty or white cement etc. Actual process can be defined as:

White cement paint- one cote of wall putty- Primer-Rubbing- Primer-2^nd cote of wall putty- Primer-Rubbing-1^st cote of paint-2^nd cote of paint-3^rd cote of paint.

In case of special wall like for texture paints, you need to finish the wall upto 2^nd quote of primer.

E.    Furniture’s- Furniture is also a sort carpentry work, But we treat it as a loose items, as this can made at different location and installed at site. You need to finalize the bed designs with dimensions of each and chosen laminate shades.

F.    Lights and Switches- We need to decide the requirements of electrical points like location of AC, LCD, LED lights, hanging lights, lamps, Fan in common areas. In kitchen we need to know fridge, microwave, juicer mixers, OTG, Dishwasher, chimney etc.

G.   Optional Items- There are optional items like flooring, sanitary items, Fixtures etc, which will be provided by your builder. But if you are building your home you need to finalize these things to.

H.   Loose Items: It includes like Rugs, Carpets, Curtain and drapers etc,

Categorization done, now comes the interior decoration cost estimation. It also depends on many factors, but we will try get some idea of cost calculation. :-

Depending on the Material differentiation, Hardware and Fittings costing, availability of laminate shades, unique items placement, sizes and measurements, makes a variation in rates. Whereas all other things can be managed in purchasing items but the question is how will you do the measurements or check the measurement taken by Carpenters.

Painting, Wallpaper and false ceiling are done in same way - calculated based on area under execution,

Woodwork and furniture is measured by multiplying the front dimensions width and depth for the item. For Example. – If the wardrobe has a size of 8 ft height and 6ft width, then the costing would be 8x6x1200 = 57.6 K approximately.

While measuring Kitchen- we need to the slab area. Suppose the slab are is of 6x7 Sq Ft. and slab height is 2.6 ft then the working are will be 6x2.6+7x2.6 = 33.8 Sq Ft. for lowr portion in the same way we can do for overhead cabinets 6x2+7x2= 26 sq Ft so the total area is 33.8+26 = 59.8 SFT. So the costing will be 59.8x1400= Rs 83720

Now comes the costing calculation. Here are some common methods to calculate the costing in Ser Sq Ft:

1. Cost for Modular Kitchen – 1400 Rs/Sft to 2000 Rs/Sft (Varies due the material)
2. Wardrobes with all fittings – 1000 Rs/Sft to 1800 Rs/Sft (Varies due the material)
3. LCD Units, Study Units, Showcase – 700 Rs/Sft to 1200 Rs per Sft (Varies due the design)
4. False Ceiling – 90 Rs/Sft to 150 Rs/Sft (Varies due the design)
5. Painting – 25 Rs per SFT to 70 Rs per SFT (premium finish)
6. Wallpapers – 100 Rs/SFT to 300 Rs/SFT
7. Flooring – Tiles flooring 120 Rs/ SFT to 200 Rs/SFT ; Marble Flooring 150 Rs/SFT to 400 Rs/SFT
8. Curtains and Drapers – As per your choice only

Now you have a decent idea about the costing part and hence you can now decide what would fit in your budget and same you can discuss with your interior designer and decorator.
