Open-Plan Conversions Orpington

Open-plan kitchen, diner and living conversions in Orpington. Trusted, professional, 30+ years' hands-on experience.

GS Renovation creates open-plan spaces across Orpington, turning the compartmented rooms of 1930s and interwar homes into flowing kitchen-diners and broken-plan living areas. With over 30 years of structural experience in BR6 and the wider Bromley area, we combine engineer-designed steelwork with knock-throughs, wide openings and Crittall-style dividers.

Open-plan living in Orpington's interwar homes

The 1930s houses around Orpington were designed with separate front and rear reception rooms and a boxed-off kitchen, which no longer suits how families want to live. Opening these up almost always means removing a load-bearing wall, so we start with a structural engineer to size the steel beam that will carry the first floor once the dividing wall between the two rooms is gone.

Because these homes sit on generous plots, many owners go further and bring a rear or side extension into the same open scheme, or choose a broken-plan layout using a Crittall-style glazed divider to keep the kitchen slightly separate. Whatever the layout, the loads must land on properly sized beams and padstones, which is where the engineer's calculations and our steelwork come together.

Knock-throughs done properly in BR6

A knock-through in an Orpington semi is notifiable under the Building Regulations, so Bromley Council's building control inspects the beam, bearings and padstones before they are hidden. This is not planning permission, which you do not need for internal open-plan work unless your home is listed or in a conservation area with external changes near Chislehurst or Beckenham.

Where the wall being opened is shared with the adjoining semi, the Party Wall Act applies and you serve notice first. On site we prop the floor above, remove the wall in stages, lift the steel onto its padstones and fireline-case it, then finish the kitchen-diner or broken-plan room so the join is seamless. One team runs the whole conversion from engineer's survey to final sign-off.

FAQ

Frequently Asked Questions about Open-Plan Conversions Orpington

How much should open-plan conversion in Orpington cost?

Only a survey answers that honestly. Two Orpington houses of the same size can differ once open-plan conversion is scoped, so we look at the BR6 property first, then price the structure, the trades and the Bromley Council approvals as separate lines you can compare. That written quotation is what GS Renovation stands behind across Bromley and Beckenham. Nothing is owed for the BR6 survey if you decide against going ahead with open-plan conversion in Orpington. As a rough guide, open-plan conversion in London typically costs from roughly £3,000 to £8,000 or more, including the steel beam and finishing (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.

How many weeks should I allow for open-plan conversion in Orpington?

More weeks than the structural work alone suggests. Once the beam or the opening is in at your BR6 property, open-plan conversion moves into plastering, decorating and sign-off, and that phase fills out the Orpington programme. GS Renovation sets realistic dates rather than optimistic ones. Ring 07472 424 226 and we will give a range for a comparable 1930s and interwar home in Bromley. The Bromley Council inspection dates are marked on the Orpington programme from the outset.

Do you produce the structural calculations for open-plan conversion in Orpington?

We build to a design, we do not write one. Where open-plan conversion in a BR6 home involves beams, openings or altered load paths, GS Renovation appoints an independent structural engineer and coordinates them through Bromley Council sign-off. That separation protects the Orpington homeowner. Propping and sequencing on site are then ours to get right. Ring 07472 424 226 and we will explain the Bromley sequence. The engineer is appointed and paid through the Bromley contract.

Do I need planning permission for an open-plan conversion in Orpington?

Internal work in an Orpington house does not normally engage planning, but removing a load-bearing wall needs building regulations approval, engineer's calculations and Bromley Council sign-off. If the wall is shared with a neighbour the Party Wall Act may apply too. GS Renovation manages the whole process.

Do you have experience of open-plan conversion in 1930s and interwar buildings across Bromley?

Yes, across the borough and well beyond it. Open-plan conversion in older housing takes GS Renovation to Orpington, Beckenham and the surrounding South East London regularly, which is what makes a BR6 quotation accurate. Bromley Council building control is coordinated by us on every one. References are available before you commit to anything. Ring 07472 424 226 and we will describe how open-plan conversion was handled on a comparable BR6 property, and put you in touch with the owner.

Can I make my 1930s Orpington semi open-plan, and what's involved structurally?

Yes. It almost always means removing the load-bearing wall between the two reception rooms, so a structural engineer sizes a steel beam to carry the first floor onto padstones. Bromley building control signs off the work under the Building Regulations, and where the wall is shared with next door the Party Wall Act applies. We handle the engineer, steelwork as one job.

Do you take on open-plan conversion across the whole of Bromley?

The whole borough, and a good way beyond it. GS Renovation carries out open-plan conversion across Orpington, Beckenham and much of South East London, with no surcharge for distance within Bromley. Knowing the Bromley Council building control process locally is a practical advantage on a BR6 job. Email info@gsrenovationltd.co.uk with the address for a free survey. We will say plainly if a property is too far out. Aftercare is no harder from one end of the borough to the other.
