Open-Plan Conversions Hitchin

An open plan conversion is a wall removal, a beam, a floor that has to run through and a set of services that have to move. We manage the whole sequence under one contract, appoint the structural engineer for the calculations and build to what they issue. We do not produce those calculations. This page sets out what an open plan scheme involves on a Hitchin house.

For Hitchin, 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 Hitchin: 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 Hitchin 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.

An open plan scheme in the Hitchin Conservation Area can still need planning permission

The Article 4 direction over the Hitchin Conservation Area removes permitted development rights for the enlargement, improvement or other alteration of a dwellinghouse. Rearranging rooms behind an unchanged elevation is one thing. A scheme that also widens a rear opening, adds glazing or takes in a side return changes the outside of the house, and inside that area those changes need a planning application.

We establish which conservation area, if any, covers your address at the survey stage, and we give you the consent route before you commit to a layout. Settling the layout first and finding the constraint second is the expensive order to do it in.

Housing in Hitchin

Hitchin counts roughly 16,130 homes for Council Tax; 14% are older than 1919, 16% interwar and 69% post-war, with 30% flats and 70% houses. A semi in Hitchin usually opens up with one beam, one end on the shared wall, and 28% of homes here are semi-detached.

Town centre plots off the High Street and Bancroft are long and narrow

Medieval burgage plots survive on the western side of High Street in Hitchin and on both sides of Bancroft. They produce long thin building plots, reflected in places by alley ways, carriage entrances and courts. The pattern is set out in the council's adopted character statement for the conservation area.

A long thin plot suits a knock through along its length, and it makes the rear the natural place to bring light in. It also decides how the steel gets in, where a skip can stand, and whether a beam comes through the front of the house or down an alley. We measure the carry route at survey, including the turn at the doorway and the ceiling height inside.

Outside the conservation areas the planning question is a different one

Late 19th century terraced housing in the Lancaster Road, York Road, Duke's Lane, Ickleford Road and Bunyan Road area was inspected during the 2011 conservation area review. It was rejected as being too altered to merit conservation area status, so the review did not bring those streets into a conservation area. The Article 4 direction over the Hitchin Conservation Area does not reach them.

That changes the planning question, not the structural one. The beam, the bearings, the floor build up and the fire and escape arrangements are still inspected, and the engineer's calculations are still needed. We confirm the designation for your address rather than reading it off the street name.
