Open-plan kitchen, diner and living conversions in Royston. Trusted, professional, 30+ years' hands-on experience.
An open plan conversion joins rooms that were built to be separate. It can mean several openings rather than one: walls out, beams in, services rerouted, floors levelled and the whole space finished as a single room. We coordinate the structural engineer, build to their calculations and arrange the building control inspections. This page covers what open plan means on a Royston property, where the shape of the plot sets the shape of the room.

The council's townscape analysis records a medieval town layout, with buildings set abutting the road on long narrow burgage plots. The narrowest end faces the street, the house or shop stands nearest the road, and the workshops and outbuildings sit in the plot behind.
Rear ranges and outbuildings behind the frontage buildings are set at right angles, follow the narrow shape of the plots and step down in height from the building on the street. Joining a front room to a rear range therefore means dealing with a change in direction and a change in floor and ceiling level, not only with the removal of a wall.
The council records that in the High Street the narrow elongated medieval plots have largely been joined to form larger squarer plots, and that behind Upper King Street the medieval plot form is no longer discernible. A squarer plot gives a different set of options at the rear from a narrow one.
Kneesworth Street changes character midway along its length. At the southern end there are narrow fronted shops with continuous facades. At the northern end there are detached and semi detached houses in individual garden plots, set back behind brick walls or iron railings. Two addresses on one street can need two entirely different approaches.
In King Street, the High Street, and the parts of Kneesworth Street, Baldock Street and Melbourn Street closest to The Cross, the council records the building frontage following the back pavement edge with very few breaks between buildings. There is no side route into the plot where the frontage is continuous.
Steel, props, plasterboard and waste all travel that route, and a beam has to turn inside the doorway once it is through it. We measure the carry route at survey and agree the delivery point and the sequence with you before the steel is ordered. Where one long beam cannot be brought in, the engineer designs around what can.
Open plan is a sequencing problem more than a single structural one. Several openings, the services that ran inside the walls being removed, the floor levels and the ceiling line all have to be resolved in one order, by one team. We appoint the structural engineer, build to the calculations issued, and run the temporary support, the steelwork, the first fix and the finishes as one programme with one point of contact. Access is settled at survey, before anything is ordered, because the carry route decides what beam is even deliverable.

FAQ
Accurate, because it is written after a survey rather than before one. GS Renovation inspects the SG8 property, confirms what open-plan conversion requires there, and prices the structure, the trades and the North Hertfordshire District Council approvals against that scope. The figures hold unless you change the specification or the bay-fronted Victorian terraced building reveals something nobody could see. Both possibilities are explained beforehand. Ring 07472 424 226 to hear how a Royston figure for open-plan conversion is built up. 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.
Building control does, and for Royston that is Hertfordshire Building Control Limited rather than a council department. North Herts Council owns the company jointly with seven other Hertfordshire local authorities. Where two or more rooms become one space, the route from the upstairs bedrooms to the front door forms part of what is assessed, alongside the beams. We raise it with them before the layout is fixed, so any alarm, door or window requirement is priced.
Not by conservation area status alone. There is no Article 4 direction anywhere in Royston, so householder permitted development rights have not been withdrawn here. Listing is what reaches inside a building. Four buildings in Royston are listed grade I, the Manor House in Melbourn Street is listed grade II star, and listed building consent covers work affecting character indoors as well as out. Check the status of your address with the council first.
It can be done, but it becomes a groundwork job with a design of its own. Rear ranges behind Royston's frontage buildings step down in height from the building on the street, so the floors do not line through. British Geological Survey mapping records no superficial deposit across the centre of town, with chalk immediately beneath the topsoil. Lowering a floor beside a wall changes what supports that wall, so the engineer designs it.
Yes, and doing both together means one propping design and one set of inspections. Chimneys are named in the council's conservation area assessment as a characteristic feature of Royston. They are described as important to views of the town from the higher ground to the south, so a stack above roof level can be kept while the breast below it goes. Whatever is left standing needs support, and the engineer designs that alongside the beams.
