Open-Plan Conversions Cheshunt

GS Renovation forms open plan living space in Cheshunt homes by removing internal walls and replacing them with sized steel. The engineer's design comes first, then the propping, then the beam, then the services and finishes. We coordinate the building control application and inspections, and you get one point of contact throughout.

For Cheshunt, on London-derived ranges a knock-through finished as one room typically costs £3,000 to £8,000 or more, including the steel beam; Hertfordshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Cheshunt: the structural engineer we appoint designs the steel, we install it, and building control signs it off.

How the job runs

1. Free site survey at your Cheshunt address, covering the walls, services and floor levels, and an itemised quote.
2. The engineer we appoint sizes the beam, and the work is registered with Hertfordshire Building Control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. Props in, opening cut, beam on padstones; then floors, heating and electrics are joined up.
4. Building control inspects the steel before it is covered. We finish the room, and the completion certificate follows.

Two build periods, two starting points

Cheshunt's houses cluster in two periods, and each sets a different starting point. In the six middle layer super output areas covering Cheshunt, 25.5 per cent of council tax properties were built between 1955 and 1964, the single largest build period band. In the Rosedale area, 48.2 per cent were built between 1965 and 1982.

Neither figure tells you what a particular wall is carrying. It tells you what to check. The engineer inspects the wall, the floor above and the roof structure, then sizes the beam for the span you actually want rather than the span that is convenient to build. That is settled before a start date is offered.

Housing in Cheshunt

On the valuation list Cheshunt counts about 18,660 homes, 25% flats and 75% houses; 6% predate 1919, 9% are interwar and 84% post-war. Terraced houses make up 41% of homes here, and opening up a terrace in Cheshunt usually lands one beam end on the party wall.

Terraces need the bearings planned early

In a terrace the beam ends have fewer places to go. At the 2021 census, 35.2 per cent of Cheshunt households lived in a terraced house, a higher share than the 30.7 per cent in semi-detached houses. A bearing into a shared wall brings the Party Wall etc. Act 1996 into the programme, and you serve notice as building owner before dates are fixed.

Opening up also moves services. Radiators, sockets, switches and the kitchen extract route can all sit in the wall you are taking out, so first fix is planned before demolition starts. We set the order of trades at quotation stage, so plastering is not held up waiting on an electrician who was booked too late.

Inspection hold points on an open plan job

Building control inspects at set stages, and those stages control the programme. Building control for the Borough of Broxbourne is provided by Hertfordshire Building Control Limited, which is jointly owned by Broxbourne Borough Council and seven other Hertfordshire local authorities. It sees the propping and the formed opening, then the beam on its padstones with the bearings still exposed.

Nothing is boarded or plastered over a bearing until it has been seen. That one rule shapes the whole sequence, because uncovering a bearing later is slow and it is expensive. A final visit follows the making good, and the completion certificate is issued after that. We book each visit rather than leaving it to you.

Fully insured, free no obligation quotations.
