Construction

A development, from land purchase to handover

Two or three years, many actors, and documentation that outlives all of them.

Updated on 13/08/2026

A development lasts two or three years and passes through designers, contractors, subcontractors, sales agents, buyers and finally a residents' association. Almost nobody is there from start to finish — except the documentation, which has to outlive all of them.

The four phases and what accumulates in each

PhaseWhat documentationWho will ask for it later
Land and permitsTitle, permits, conditionsThe buyer, the bank, the association
Design and contractingDesign, contracts, insuranceThe insurer if there is a claim
ConstructionSubcontractors, materials, controlsWhoever claims a defect
HandoverBuilding file, certificates, warrantiesEach buyer, for years

Important

The fourth column changes how everything before it is stored. None of this is filed for you: it is filed for someone who will ask for it in three, five or ten years, when whoever assembled it has left the company.

What gets lost most

Watch out

Handing over the building file without a signed receipt is the error that reappears most: three years later a buyer says they never received it, and without a receipt the argument has no way out.

What must be answerable years later

Who executed each part, what material was used, what was handed to whom and when warranties started running. All four are answered with dates or not at all, and all four arrive when nobody remembers.

Worth knowing

If you run several developments, building them as one process makes the third cost a fraction. What changes is the land and the buyers; the documentary skeleton, little.

Can I give the residents' association access at the end?

Yes, scoped to what belongs to them as owners.

And the contractor during the works?

Scoped to their part and with an end date.

How long must it be kept?

New-build warranty periods are long; confirm with your adviser.

A real case

The situation

A developer receives a claim three years on and cannot find the certificate for the material used.

What you do

  1. Builds the next development as a process, with certificates linked to each work package

What you get

The next claim is answered within the hour instead of absorbed for lack of proof.

The situation

The development advances and each stage files its papers separately.

What you do

  1. Uses one file per development

What you get

There is one picture from start to finish.

The situation

At handover, documentation from the construction stage is missing.

What you do

  1. Requests as the event happens

What you get

Handover does not uncover months-old gaps.

The situation

Each trade delivers whenever they remember.

What you do

  1. Requests and chases automatically

What you get

The final month goes on reviewing.

The situation

Buyers ask and there is no file per home.

What you do

  1. Also organises by unit

What you get

You answer the way people ask.

The situation

Years later a warranty claim arrives.

What you do

  1. Keeps the file beyond handover

What you get

The warranty period is faced with the record.
