GS Renovation works across Enfield from a registered office in Potters Bar, EN6, a few miles north-west of Enfield Town along The Ridgeway. That proximity is the practical reason we take on so much work here: an early start in EN1 or EN2 does not begin with an hour of the North Circular, and a snagging visit is a genuine possibility rather than a scheduling problem. We cover EN1, EN2, EN3 and EN4 and the N9, N13, N14, N18 and N21 postcodes, from Edmonton and Palmers Green up through Enfield Town, Southgate, Winchmore Hill, Cockfosters and Hadley Wood.
The firm is run by Abdelaaziz Saaid, who has more than 30 years of hands-on experience on London properties. GS Renovation Ltd was incorporated in 2023 to formalise that trade. We are a building contractor with a structural specialism, which means we install the steel beams and take out the load-bearing walls ourselves rather than subcontracting the part of the job that carries the most risk. We are not structural engineers: on any structural work we appoint an independent engineer, build to their calculations and put the work in front of building control.
The building work Enfield houses actually need
Enfield's housing is more mixed than its suburban reputation. Of about 128,000 homes on the Valuation Office list, 41% were built after 1945, 35% between the wars and 23% before 1919, and 41% are flats. Among the houses, terraces outnumber semi-detached and detached homes together by almost two to one: Victorian and Edwardian terraces around Edmonton and Bush Hill Park, interwar terraces and semis through Palmers Green, Winchmore Hill and Southgate, and larger detached homes on the northern edge near Forty Hall, Clay Hill and Hadley Wood.
The problems are usually services. Original wiring, lead or early copper pipework, single skin rear additions and gas fires blocked up rather than removed are all common. The opportunity is the layout. Interwar terraces and semis were built with a front room, a back room and a small galley kitchen, and the wall between the two receptions is almost always the one homeowners want gone. It is frequently load bearing, so it needs a steel beam sized by a structural engineer, propping and building control sign-off, which is the part of the job we do ourselves rather than subcontract.
The other Enfield advantage is garden depth. Plots here are generally longer than the inner London average, so a single storey rear extension often works comfortably within permitted development rather than needing a full planning application. A wraparound usually does not: joining the side return to the rear extension normally falls outside Class A and needs a planning application. That is worth checking properly before you commission drawings.
- Full house refurbishments, rewiring, replumbing, heating, plastering and decoration
- Kitchen and bathroom installation, from strip out to final seal
- Steel beam (RSJ) installation and load-bearing wall removal
- Chimney breast removal with the stack above properly supported
- Rear, side return and double storey extensions
- Structural openings, new joists and supported alterations
- Building control notification, inspection and sign-off on all notifiable work
Enfield Council, planning and party walls
Building control for the borough sits with Enfield Council, or with a registered building control approver if you choose one. Notifiable work has to be notified before it starts, inspected at the defined stages and certified on completion. We make the application and book the inspections as part of the job.
Enfield has conservation areas across the borough, including Forty Hill, Enfield Town and Clay Hill, and a 2006 Article 4(2) direction covering named properties in several of them. In a conservation area a single storey rear extension can still be permitted development within the limits, unless an Article 4 direction removes it, but side extensions, two storey rear extensions, roof enlargements and external cladding need planning permission. Internal structural work is a building regulations matter rather than planning, unless the house is listed, when listed building consent covers internal work too.
On any semi-detached or terraced house, cutting a beam into the shared wall or removing a chimney breast built into it triggers the Party Wall Act. You serve the notice on the neighbour as building owner before work starts, and we give you the drawings and programme it needs. We flag it at quotation stage, not once the scaffold is up.
Working on Enfield streets
Most of the borough is not in a controlled parking zone, so deliveries, skips and a materials van are usually straightforward. Skips still need a licence from the council where they stand on the highway, and we arrange that.
Access on a semi is generally good, with a side passage on one flank, which makes muck away and materials handling far easier than on a mid-terrace, where everything comes through the house. Where a passage is shared or gated, we agree access with the neighbour before we start rather than on the day.

FAQ
Frequently Asked Questions
Do you cover the whole of Enfield?
Yes. We work across EN1, EN2, EN3 and EN4 and the N9, N13, N14, N18 and N21 postcodes, which covers Enfield Town, Edmonton, Palmers Green, Southgate, Winchmore Hill, Bush Hill Park, Enfield Highway, Cockfosters and Hadley Wood. Our registered office is in Potters Bar, EN6, a few miles north-west of Enfield Town, so Enfield is one of our closest working areas.
Do I need planning permission for a rear extension in Enfield?
Often not. Many single storey rear extensions on Enfield houses fall within permitted development, and plot depths in the borough are generally generous enough to make that work. The limits on depth, height and eaves are specific. In a conservation area such as Forty Hill or Enfield Town a single storey rear extension can still be permitted development unless an Article 4 direction removes it, so check whether your address is named in the council's Article 4 list. Flats have no householder permitted development. We check the position before any drawings are commissioned.
Can you take out the wall between the two reception rooms in an Enfield house?
This is one of the most requested jobs in Enfield and yes, we do it regularly, in interwar terraces and semis alike. That wall is usually load bearing, so a steel beam sized by the structural engineer we appoint carries the load, we prop the structure temporarily and install the beam, and building control inspects and signs the work off. Where the beam bears into the party wall, you serve a Party Wall Act notice as building owner, and we give you the drawings it needs.
Do I need to tell my neighbour before work starts?
Where the work affects the shared wall, which includes inserting a beam into it or removing a chimney breast built into it, the Party Wall Act requires you, as building owner, to serve formal notice on the neighbour before work begins. We identify this at quotation stage and give you the drawings and programme, so there is time to serve notice without delaying the start.
How much does building work cost in Enfield?
Enfield work is priced at London rates. As a guide, a steel beam over a single opening is £1,500 to £4,000, a full knock-through £2,500 to £6,500 or more, a mid-range bathroom £7,500 to £12,000, a mid-range kitchen £20,000 to £40,000, and a mid-range full refurbishment £1,500 to £2,200 per square metre. These are indicative London ranges from MyBuilder and Checkatrade, 2026. Every job is quoted from a survey.
