Open-Plan Conversions Royston

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.

For Royston, 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 Royston: 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 Royston 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.

Royston's medieval plots are long and narrow, and that sets what open plan can be

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.

Housing in Royston

The stock in Royston runs to roughly 8,040 dwellings, 20% of them flats and 80% houses, built 10% before 1919, 4% between 1919 and 1939 and 86% after 1945. Opening up a terrace in Royston usually lands one beam end on the party wall, and 26% of homes here are terraced.

In parts of Royston the historic plot pattern has already gone

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.

Where buildings meet the back of the pavement, everything comes in through the front

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.

• Steel beam installation to remove the dividing wall
• Zoned lighting circuits and dimming for a multi-use room
• Bi-fold and sliding door openings onto the garden

Why Choose GS Renovation in Royston

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.
