Single and double storey extensions in Ware. Trusted, professional, 30+ years' hands-on experience.
GS Renovation builds extensions in Ware, from single storey rear additions to larger structural work at the back of a house. We appoint the structural engineer, build to the calculations, and coordinate the building control application and the inspections. We are fully insured, and quotations are free and without obligation.

In the centre of Ware the boundary between two very different deposits runs close by. The British Geological Survey maps Alluvium at the High Street sample point and Kempton Park Gravel at Bluecoat Yard, roughly 120 metres away. It maps Alluvium at Broadmeads and Kempton Park Gravel at Amwell End, roughly 150 metres away. Alluvium is a soft, variable and compressible deposit, so ground conditions can change materially over a short distance in the town centre.
The mapped pattern follows the river. Alluvium, described as clay, silt, sand and gravel, is recorded at High Street, Broadmeads, Star Street, Viaduct Road, Marsh Lane, Kingsmead and Chadwell Spring. Kempton Park Gravel, mapped as sand and gravel, underlies Amwell End, Bluecoat Yard, New Road and Priory Street. Foundation depth and design follow trial holes on your own plot, not the nearest mapped point.
Park Road, formerly Park Lane, had industry on both sides of it. Ordnance Survey mapping from 1874 to 1894 shows a very large gravel pit north of Park Lane, and mapping from the early 1920s shows that the pit no longer existed. The same 1874 to 1894 mapping shows what the conservation area appraisal interprets as large scale brickworks with associated engine houses south of Park Lane.
By the early 1920s the brickworks site had been significantly reduced in size, with allotments over a large part of it. The British Geological Survey artificial ground layer records no made ground at any of the 25 Ware street locations sampled. That is a mapping result at 1:50,000 scale and it does not replace a site investigation. It is why the engineer specifies trial holes on the plot rather than relying on mapping.
The local planning authority is East Herts District Council, which has 42 conservation areas, and Ware Conservation Area is one of them. There is no Article 4 direction in force in Ware. The Ware Conservation Area Appraisal identifies individual buildings as candidates for a future Article 4 direction rather than recording one already in force. East Herts made two Article 4 directions on 14 June 2017 for Bishop's Stortford Conservation Area only, confirmed as permanent on 15 November 2017.
Trees on the plot carry their own timetable. In a conservation area such as Ware, six weeks notice must be given to East Herts District Council under a Section 211 notice. That applies before work on a tree with a trunk diameter greater than 75mm that is not already covered by a Tree Preservation Order. If an extension needs a tree removed or reduced, that notice period sits in front of the build, so it goes in early.
Ware Neighbourhood Plan Policy W2 asks proposals to demonstrate how they have addressed the guidance in the Ware Conservation Area Appraisal. It asks them to conserve those features identified as contributing to the particular Identity Area, and to the River Lea Navigation character corridor. That is a design test with a document behind it, so a rear extension design has to answer it in writing.
Knowing which Identity Area you are in comes first. The Ware Conservation Area is divided into four Identity Areas. The 2016 appraisal does not map them, and the Ware Neighbourhood Plan mapped them at its Figure 5.1 to fill that gap. That figure is the place to start when an architect or designer is briefed on a Ware extension.
Ware homeowners choose GS Renovation for extensions because the foundations are settled before the price is. Ground conditions in the town change over short distances, so we work from the engineer's trial holes and calculations rather than from an assumption. We build to that design, coordinate the building control application and inspections, and keep one point of contact from the first survey to the completion paperwork.

FAQ
Accurate, because it is written after a survey rather than before one. GS Renovation inspects the SG12 property, confirms what house extensions require there, and prices the structure, the trades and the East Herts District Council approvals against that scope. The figures hold unless you change the specification or the period, Georgian and listed building reveals something nobody could see. Both possibilities are explained beforehand. Ring 07472 424 226 to hear how a Ware figure for house extensions are built up. As a rough guide, house extensions in London typically starts from roughly £40,000 for a single-storey rear extension and rises with size and specification (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.
That is settled with the channel's owner and East Herts District Council before the design is drawn. Chadwell Spring, on the western edge of Ware, is the head of the New River, which opened on 29 September 1613 to carry Hertfordshire water to London. It remains a live channel with its own access and maintenance needs. The British Geological Survey also maps Alluvium at Chadwell Spring, so foundation depth follows trial holes on the plot.
It can. Gilpins Field, at the junction of London Road and Viaduct Road, is owned by Thames Water, and the Ware Neighbourhood Plan treats its openness as an important gateway to the conservation area that should be protected. An extension seen from that gateway is judged on what it does to that openness. Height, roof form and boundary treatment carry more weight there than they would on an enclosed plot.
It means part of your plot carries statutory protection. The riverside gazebos on the Lea carry statutory listing, and the Ware Neighbourhood Plan treats them as an important feature of the river's character within the River Lea Navigation character corridor. Ordnance Survey mapping of 1874 to 1894 records about 15 gazebos standing south of the High Street. Structures inside a listed building's curtilage that pre-date 1948 carry the same controls as the listed building.
Yes, where the Party Wall etc. Act 1996 applies, and that includes excavating within three metres of a neighbouring structure to a level below its foundations. The notice periods run in weeks, so they go out early. Where the British Geological Survey maps Alluvium, a soft and compressible deposit recorded along the Lea corridor here, foundations can go deeper and that notice becomes more likely. We are contractors, not party wall surveyors.
A build over agreement is needed from the sewerage undertaker before the slab is laid, and the extension may have to move around the run. The East Herts District Plan records that waste water from the growth north and east of Ware will drain to Rye Meads Waste Water Treatment Works, with a new sewer linking into the existing network east of the town. A drainage survey at the start settles what crosses your plot.
