Everything You Need to Know About House Construction Specifications (Before You Build Your Dream Home!)
If you’re planning to build your own house — or even just thinking about it — this breakdown will help you avoid confusion, surprise costs, and vague promises.
A construction specification is simply the complete list of materials, brands, dimensions, and methods your builder has promised to use — from the foundation all the way to the final coat of paint.
Think of it like checking the RAM, storage, camera and battery before ordering a phone. You’re not just paying for “a house”. You’re paying for exactly what goes into that house.
The Big Number ₹2,350 per sqft – what it means
Residential Dream Home package with RCC framed structure.
The ACASA Residential Dream Home package starts at ₹2,350 per sqft using an RCC framed structure — columns, beams, and slabs in reinforced concrete instead of old-style load-bearing brick walls.
RCC framing is like the skeleton of your home. It carries the load, handles earthquakes better, and gives you flexibility for bigger openings and future floors.
What this price covers
It’s not just “material + labour”. It includes:
- Structural design and RCC frame.
- Defined specs for walls, tiles, doors, windows, and painting.
- Named brands for electrical and plumbing wherever possible.
What this guide will show you
- What exactly is included in the rate.
- Which brands and dimensions are promised.
- What is not included and must be budgeted separately.
1. The Plan What you get on paper
Everything starts with clear drawings.
Before anyone touches the site, you’ll get a complete planning package. This is where you lock your layout and avoid “last-minute changes” later.
- 2D floor plan with two design options for you to choose from.
- 3D elevation reference images so you can visualise the front view of your house.
- Working drawings that engineers and contractors use on site for accurate measurements.
Take your time here. Any major change you make after construction starts will cost extra money and delay.
2. Structure The bones of your house
If this is wrong, nothing else can fix it.
The structural specification defines the strength, stability, and lifespan of your home.
- Main walls: 9 inch brickwork using cement mortar CM 1:6.
- Partition walls: 4.5 inch brickwork using CM 1:4.
- Internal plaster: CM 1:5.
- External plaster: CM 1:4.
- Structural concrete: M20 (1:1.5:3) for columns, beams, lintels, sunshades, and roof slabs.
- Base concrete: M10 (1:4:8) for bed concrete below foundations.
- Finished ceiling height: about 10 feet per floor.
- Basement height: up to 3 feet above existing ground level after levelling.
- Parapet wall: 9 inch thick, 3 feet high.
- Roof slab waterproofing with Dr. Fixit / Fosroc / Bostik (for built-up area above 2,000 sqft).
- Rainwater harvesting provided as part of the structure.
- Cement: branded options such as UltraTech or Ramco.
- Steel: Pulkit Fe 550D corrosion-resistant TMT bars for better strength and rust resistance.
Structural design is done based on the actual number of floors you plan to build.
3. Doors & Windows Security, light and ventilation
These are what you touch and see every day.
Doors and windows affect privacy, security, looks, and airflow.
- Main door frame: first quality teak, 5″ × 3″.
- Main door shutter: first quality teak plank, about 3.5′ × 7′.
- Bedroom doors: country wood frames (4″ × 3″) with laminated flush door shutters (budget up to ₹3,500 per shutter).
- Bathroom doors: readymade PVC doors.
Teak for the main door gives a premium entrance; bedrooms are kept practical and economical; bathrooms get moisture-resistant PVC.
- All windows: UPVC 3-track sliding with mosquito mesh, standard size 4′ × 4′ in white.
- MS grills with simple square design provided for windows.
- Louvered glass ventilators for bathrooms and wet areas.
UPVC windows are low maintenance — no rust, no termites, and better sound insulation than basic aluminium frames.

The hardware used on doors decides how secure and comfortable they feel.

Colour, design, and brand of tiles are discussed and finalised with you. The main limit is the per-sqft budget.
6. Kitchen Where the magic happens
