Know the extras before you start

1. 01

   Rock breaking / hard-rock excavation

   ₹50,000 – ₹2 lakh

   Granite close to the surface is common in parts of Hyderabad such as Kukatpally, Secunderabad, Shamshabad, Banjara Hills and Jubilee Hills. Breaking it for the foundation is slow and costly.

   engineeringHow we handle it: we look for visible signs of rock at the free plot check, and the soil test confirms it before design. If rock is likely, it goes on your written extras list with a range before you sign.

2. 02

   Borewell (drilling, casing, pump)

   ₹80,000 – ₹1.5 lakh

   Telangana's hard granite makes borewells deeper and costlier than in many cities. A hard-rock surcharge of about ₹20–60 per ft can apply. A borewell also needs permission under the Telangana WALTA Act.

   engineeringHow we handle it: quoted separately, with per-ft drilling rates written down so you can see how depth changes the cost.

3. 03

   Sump and overhead tank

   ₹40,000 – ₹1 lakh

   Most Hyderabad homes need a sump for municipal (HMWSSB) water plus an overhead tank. Size and waterproofing drive the cost.

   engineeringHow we handle it: sized in your drawings, and shown in your estimate as a separate line so you can see it.

4. 04

   Building permission fees + labour cess

   about ₹15–25 / sq.ft + 1% cess

   Permission fees and development charges for GHMC or HMDA plots, plus a 1% labour cess on construction cost. The BuildNow portal calculates the exact amount.

   engineeringHow we handle it: we prepare the drawings and certificates and apply for you; the government fees are paid by you, and we tell you the expected figure in advance.

5. 05

   Soil test and plot survey

   ₹10,000–25,000 + ₹5,000–10,000

   A geotechnical (soil) report fixes the foundation type; a boundary and level survey fixes the plan on the land. Both come before design.

   engineeringHow we handle it: these are not part of the free plot check. We tell you the cost before you commission them.

6. 06

   Compound wall and gate

   ₹800–3,000 / running ft

   A 5–6 ft wall costs by length and type, from a 4.5" block wall to an RCC frame or stone. A MS sliding or swing gate is typically ₹30,000 – ₹75,000.

   Septic tank (no underground drainage)

   ₹75,000 – ₹1.4 lakh

   Material price rise

   5–8% possible rise

   Steel and ready-mix demand peaks from October to March. If your price is not fixed, a rise can be passed on to you.

10. 10

    Monsoon and approval delays

    +2–6 weeks; approvals 4–12 weeks

    Monsoon can add 2–6 weeks. Approval typically takes 4–8 weeks in GHMC and 6–12 weeks in HMDA. Every extra month can mean more rent while you wait.

    engineeringHow we handle it: a written timeline with stage dates, and early notice from our engineer if weather or approvals move the date.
