Package FAQ

Before you choose.

What is the construction cost per sq ft in Bangalore?

Our residential packages start from the Essential rate shown above and rise with the specification — Premium and Signature add better brands, finishes, design deliverables and supervision. The estimator calculates your cost floor by floor, including sump, septic tank, compound wall and GST.

Are these rates final?

They are indicative rates for standard specifications, exclusive of GST. The final price is confirmed in a written proposal after a site assessment, soil conditions and your selections.

What is included in the package price?

Design deliverables, structure, finishes, plumbing, electrical and project management as listed under each tier. Each tier also lists what is not included, such as approval fees, utility connections and lift equipment.

How much does a PEB shed or warehouse cost?

PEB rates are per sq ft of plan area and depend on span, height, roofing and cladding. Enter the length and width in the estimator and add PUF roofing, skylights or MS structures to see an itemised figure.

Do you build outside Bangalore?

Yes. We serve clients across Karnataka, Andhra Pradesh, Telangana and Tamil Nadu. Share your project location when you enquire.

Can I take only the architectural design package?

Yes. The design-only packages give you construction-ready drawings — floor plans, 3D elevation, structural, electrical and plumbing drawings — for your own contractor.

Need a tailored scope?

Share your drawings or brief. We will prepare a detailed proposal.
