Open-Plan Conversions Rickmansworth

GS Renovation opens up ground floors in Rickmansworth houses, taking out the walls between front and rear rooms and putting in the steel that replaces them. The engineer we appoint sizes the beams and we build to those calculations. Building control applications and inspections are coordinated, and there is one point of contact for the whole job.

For Rickmansworth, 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 Rickmansworth: 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 Rickmansworth 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.

Why the town centre plots make open plan worth doing

The rooms are narrow because the plots are. The Batchworth Neighbourhood Design Code describes the building plots in the historic retail core of Rickmansworth as narrow in width and long, with buildings flush to the street. Rickmansworth town centre is enclosed by the Grand Union Canal to the south and the Metropolitan line to the north, and the town retains its medieval core based on the High Street and Church Street.

A narrow, deep plan divided into small rooms takes its daylight from two ends only. Removing the dividing wall lets the front and rear windows serve a single space, which is the whole point of the work. That wall was also bracing the flank walls, so the replacement beam and its bearings are designed for more than the vertical load. Buildings flush to the street mean no side access, which changes how steel, props and spoil move in and out.

Housing in Rickmansworth

Roughly 11,770 dwellings sit on the valuation list for Rickmansworth. 74% are houses and 26% flats, and by age 8% predate 1919, 20% are interwar and 72% post-war. A detached house in Rickmansworth allows wider openings with no party wall notice, and 35% of homes here are detached.

What turns up when the plaster comes off

Older fabric than the frontage suggests. Church Street in Rickmansworth retains 16th and 17th century timber framed houses that were later covered by Georgian and Victorian brick facades. Bury Lane continues the scale of Church Street with modest Victorian terraced housing. Norfolk Road has an area of late Victorian terraced housing associated with the canal and known as Riverside Terraces.

Those are three different structures behind three similar looking fronts. A timber frame under a brick skin needs the frame understood before anything is cut, because the skin may not be the load path. A modest Victorian terrace gives you short bearing lengths and lime mortar that does not tolerate heavy breaking out. We strip back, prop, and let the engineer see the actual construction before a section size is fixed, which is why we survey before quoting.

Moneyhill and the streets on either side of it

The house types differ within the same area. The Batchworth Neighbourhood Design Code describes the Nightingale Road, Upper Nightingale Road and Cedars Avenue conservation area in Moneyhill as consisting of detached houses. It describes the western part of Moneyhill as having more semi detached and terraced housing than those eastern conservation area streets. It records building heights in Moneyhill as two storeys.

Two storeys over an opening is a load an engineer can size confidently, but a semi detached or terraced house brings the party wall into the programme. Where a new beam bears into a wall shared with a neighbour, you serve notice under the Party Wall etc. Act 1996, as building owner, before work starts, and the notice period is part of your timeline. In a detached house the bearings are yours alone, which removes that step. We confirm which applies at the survey.

• Ventilation and extraction planned for an open kitchen
• Kitchen island services routed through the new floor
• Beam depth checked against existing ceiling heights
