questions

Before You
Sign.

The ten questions flat owners and societies ask most, answered without hedging.

01What is included in flat reconstruction with Buildiyo?+

Everything from structural survey and drawings through to snagging and handover, itemised in a BOQ you approve before work begins. Demolition and debris removal, structural strengthening, masonry, rewiring, plumbing, waterproofing, flooring, joinery, kitchen and bathrooms are each priced as their own lines. Society charges, statutory fees and loose furniture are quoted separately and always in writing first.

02Can I remove a wall in my flat?+

It depends on whether the wall carries load. Most internal partitions in a framed building are not structural and can go. Where an opening is needed in a structural element, it can often still be done with a designed beam and column jacketing — but that is an engineered solution with drawings and sign-off, not a site decision. We check this at survey before any design work.

03Can I live in the flat while the work is going on?+

Sometimes. Confined scope — one bathroom, a kitchen, a room, rewiring — can be zoned, sealed with dust barriers and sequenced so you keep a working bathroom and kitchen throughout. Structural work, all wet areas at once, or flooring throughout means staying is not realistic. We tell you which applies at survey, and we quote both options where the choice genuinely exists.

04How long does a flat reconstruction take?+

Survey and structural assessment take 1–2 weeks, design 2–4 weeks and BOQ and contract 1–2 weeks. Construction depends on scope and on whether the flat is occupied — working around an occupied home takes materially longer. Society approval sits between design and construction and its duration is outside our control. You get a dated programme in your contract rather than a generic range.

05Do I need a society NOC, and what does it involve?+

Almost always, and it is worth treating seriously rather than as a formality. We prepare the application with a method statement, agreed working hours, the debris route, lift usage arrangements and insurance details. Getting these agreed in writing before work starts is what prevents the disputes that stop projects halfway through.

06What happens if the society refuses permission?+

We find out why, because refusals usually have a specific cause — concern about structural work, past disruption from another contractor, or a bye-law restriction nobody had checked. Often the objection can be answered with a structural report, a revised method statement or a change of scope. Where the restriction is genuine and absolute, we tell you rather than encouraging you to proceed and argue later.

07How do you protect the flats around mine?+

Wet areas are where damage to a neighbour happens, because existing waterproofing is broken during demolition and the flat below is exposed until the new membrane is laid and ponding-tested. We sequence and test wet areas deliberately, protect common areas and the lift, clean down daily, and carry insurance for third-party damage. Your society can have that protocol in writing before granting the NOC.

08What happens if something unexpected is found after demolition?+

Some of a reconstruction scope is genuinely unknown until walls are open. When something is found, work stops on that element and you get photographs, an engineer's assessment and a priced variation against the rates already fixed in your contract. Nothing proceeds until you approve it. Nobody can promise a reconstruction with no surprises — what we can promise is that you see each one before it costs you anything.

09Do you work with housing societies on whole-building projects?+

Yes. A committee needs documents it can circulate — structural report, method statement, phasing plan, insurance certificate and a written protocol for timings, debris and common areas. We produce those as standard, and we phase the work so occupied flats stay usable while it proceeds.

10Do you design to vastu principles?+

Where a client asks for it. Vastu is a traditional system of spatial planning, not a building code, and Buildiyo makes no performance or outcome claims for it. In a flat the structure and the drainage stack set the real limits, so we work to your vastu brief within what the building physically allows, and we tell you clearly where the two cannot both be satisfied.

Still deciding? A soil test, a concept plan and a line-by-line BOQ cost you nothing and commit you to nothing.
