From the lot to the brief
Start and lot
Choose where you start, from an empty lot to a house that needs a new floor or a repair, and enter the lot.
Rooms
Add the rooms you need. The app adds walls and circulation and shows the area of each floor against the lot.
Stages
Place the stages on the months, see which fall in the wet seasons, and leave pauses to save between them.
Permits and budget
Answer a few questions about the work, tick the documents you have and look at the reference range.
Send the brief
Send it to BJS Construcciones S.A.S. for a technical visit. The price comes after that visit.
What the planner checks
Three things to settle before the first visit
Stages around the rain
Concrete, slabs, roofs and the façade are best done outside April–May and October–November.
Licence and documents
A few questions point to the likely licence, or to minor repairs that usually need none.
Worked example
A two-floor house on a 7 × 15 m lot
Living and dining, kitchen, guest toilet, laundry, storage, stairs and a 6 m² patio downstairs; a main bedroom, two bedrooms, a bathroom and the stairs upstairs. With 15 % for walls and circulation the ground floor is 46 m² and the upper floor 44,9 m². With the patio the house takes 52 m² of the 105 m² lot.
Starting in January 2027, the foundations and structure fall partly in May, a wet month, and the planner offers to move them. The reference range for a standard finish is $ 159,9 – 216,6 million, not a quote.

Cartago is in a high seismic hazard zone.
NSR-10 gives Cartago Aa 0,25 and Av 0,25. A new floor over a house, or any reinforcement, starts with a licensed structural engineer.
Building in a seismic zoneDoes the app draw my house?
No. It adds up the rooms you list into floor areas, checks them against the lot and plans the stages. Plans come from an architect.
Is the budget a quote?
No. It is a reference range from proposed bands. BJS Construcciones S.A.S. gives a price after visiting the site.
Do I need a licence?
The Permits section asks a few questions and points to the likely licence, or to minor repairs that usually need none. Planeación confirms it.
Is anything sent automatically?
No. The app has no internet access. You send the brief yourself by email, share it or read it out on a call.
Technical visit
Send BJS your brief
Plan the rooms and the stages, then send the brief from the planner or the app to ask BJS Construcciones S.A.S. for a technical visit. The price comes after the visit.
