Clear, Stage-Based Pricing

At Reltic, we believe building a home should be exciting – not confusing or full of fine print. That’s why we use a simple, fixed-fee structure based on three clear stages aligned with the RIBA Plan of Work.

There are no hidden costs, no vague percentages. Just transparency, flexibility, and total clarity from the start.
You commit to one phase at a time, and if external consultants are required (such as a structural engineer or surveyor), they are invoiced separately – always with your approval.
