Open-Plan Conversions Ware

Open-plan kitchen, diner and living conversions in Ware, steel, floors, heating and finishes as one job.

GS Renovation opens up ground floors in Ware, replacing the walls between rooms with properly supported openings. A structural engineer we appoint sizes the steel and specifies the bearings, and we prop, cut back in stages and make good afterwards. Building control applications and inspections are coordinated for you, and quotations are free and without obligation.

For Ware, 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 Ware: 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 Ware 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.

Find out what is behind the plaster before fixing the layout

The finish on a wall in Ware is not evidence of its construction. The Ware Conservation Area Appraisal records that early timber framed buildings in the town have been refaced in later materials and given later facades, so a later brick frontage can stand in front of an earlier timber frame. An open plan layout drawn against a plan of solid walls can fall apart once the plaster comes off.

We open up a small area early, before the layout is agreed and before a price is fixed. If a frame is present, the opening has to work with the posts and beams rather than through them, and the layout follows the structure instead of the other way round. That order costs a little at the start and saves a redesign halfway through demolition.

Housing in Ware

The Council Tax list puts Ware at about 8,980 homes, 34% flats against 66% houses; 12% went up before 1919, 8% between the wars and 79% after 1945. 27% of homes here are semi-detached; a semi in Ware usually opens up with one beam, one end on the shared wall.

Which streets sit in the historic core

Identity Area 1 of the Ware Conservation Area is the central historic core. It covers the High Street south to the River Lea, Church Street, part of Baldock Street and the south part of Crib Street. It also takes in West Street, East Street and Kibes Lane. If your house stands on one of those streets, the external half of an open plan scheme is where the consent questions land.

Internally, the Building Regulations govern the beam and the opening. Externally, conservation area control applies to what a new run of rear glazing or a wider opening looks like, and listed building consent applies to internal work as well where the building is listed. We settle which of those apply at survey, so the structural programme and the consent programme are not running against each other.

Where ten houses are one building

A Ware terrace can be one structure with several front doors. Nos. 3 to 12 Bluecoat Yard are Grade II star listed and are described as a terrace of ten houses that is all one building, built as nurse cottages for the Bluecoat School around 1687 to 1689. An internal wall in a range like that can be doing work for more than the dwelling it stands in.

That is why the engineer's brief covers the structure and not only your rooms. Where a wall is shared with an adjoining owner, the Party Wall etc. Act 1996 brings its own notice periods, and those run in weeks. We flag the shared elements at survey, so you can serve the notices early as building owner, using the drawings we supply, rather than the notice period becoming the reason the steel sits in the garden.

FAQ

Frequently Asked Questions about Open-Plan Conversions Ware

What is included in your open-plan conversion price in Ware?

A GS Renovation price for open-plan conversion in Ware includes everything needed to finish the work and get it signed off, within £3,000 to £8,000 or more (London-derived). That covers labour, materials, the engineer's design, the engineer's calculations and building regulations approval of the steel, and making good. Anything uncertain at the SG12 property is flagged before starting rather than added later.

Does lowering the floor level for an open plan ground floor raise archaeology?

It can. Much of Ware is covered by a broad Area of Archaeological Importance, also referred to as an Area of Archaeological Significance. The Ware Neighbourhood Plan expects a Heritage Statement where a scheme could affect archaeological remains above or below ground. Digging out below an existing slab is that kind of work. Settle the position before headroom is designed around a lower floor, because the answer can change the whole scheme.

Can the staircase open directly into an open plan room?

That is the hardest part of an open plan scheme to get past building control, because the stair is the escape route from the bedrooms. Where it discharges into a room rather than a protected hall, compensating measures are needed, such as interlinked detection, a protected final exit or a sprinkler system. Hertfordshire Building Control Limited assesses the plans for East Herts District Council, so the fire strategy is agreed before the wall comes out.

Does an open plan ground floor need underpinning on the alluvium at Star Street?

No. Taking out an internal wall adds no load to the ground, so underpinning is not a normal part of the work. The British Geological Survey maps Alluvium along the Lea corridor at Star Street, High Street, Broadmeads, Viaduct Road, Marsh Lane, Kingsmead and Chadwell Spring, and it is soft and compressible. Where the wall runs down to its own footing, the engineer checks that footing before the beam concentrates the load at two points.

Can the chimney breast come out at the same time as the wall?

Yes, and covering both in one engineer's design is tidier than coming back later. The support for whatever is left of the stack is then worked out alongside the beam, and both go into the same building control application. Ware Neighbourhood Plan Policy W2 asks for built historical features including chimneys to be retained and where possible restored, so what happens above roof level is a separate question from the room below.

What happens when the two rooms have different floor levels?

The levelling is designed with the structure, not left to a floor layer at the end. A small difference is absorbed in a screed or a battened build up. A larger one means relaying joists in one room at a new level, which moves the beam position and changes the headroom under it. The Ware Neighbourhood Plan records historic core buildings from the 16th and 17th century onwards, where level changes between rooms are part of the fabric.
