Three quotes on your table

Ours is the one you can check.

A renovation quote is a list of line items. Most of them arrive as a lump per room, so the only thing you can compare is the total, and the total tells you nothing about why.

Every line on a CHALKLINE quote carries its quantity and its rate. You can see that the kitchen is the expensive room because of eleven and a half feet of carpentry, not because of us. You can see what changes if you keep the floor. And when you change your mind, a change is a line, not a renegotiation.

Build one for your flat and read the working under the number.

How you pay

10%A week after move-in

The weeks are a real schedule, not a promise. A 4-room BTO at standard scope runs ten weeks from permit to handover; a resale flat that needs hacking runs closer to thirteen, because wet rooms have to be waterproofed and flood-tested before a single tile goes down.

You are in one WhatsApp group with the three of us for the whole job, with photographs every working day. The last ten percent waits until you have lived in it for a week.

The full process, and what we won't do

Start with your plan

Pick your flat. Tick the rooms. Watch the number.

The estimate rebuilds itself from the plan's own measurements and prints the working underneath. Then send it to us as it is.
