Refurbishing Eltham interwar family homes
Many Eltham houses still have the small, boxed-off rooms and dated services of their interwar build. A full renovation lets us rewire and replumb throughout, replace tired plaster, and reconfigure the ground floor into the open, connected space modern families want. Where we remove internal walls, we install steel beams sized by a structural engineer and signed off by building control, so the changes are as sound as the original brickwork.
These homes often retain features worth keeping, such as original coving, picture rails, panelled doors and fireplaces. We restore what suits the character of the house while quietly modernising everything behind the walls. Working on the generous SE9 plots typical of the area, we can set up properly and keep the project moving without cramping the site or your neighbours during the works.
Housing in Eltham
Of the 14,360 homes the valuation list records in Eltham, 17% were built before 1919, 52% between the wars and 30% since 1945; 27% are flats and 73% are houses. 35% of homes here are semi-detached; a semi in Eltham usually has side access.
Windows, doors and room lets in an Eltham renovation
A whole-house renovation in Eltham can take in new windows and a new front door, and that is where the address matters most. If your cottage is on the Progress Estate, the council's guidance note records that the estate was granted Article 4 Direction status in 1973. Royal Greenwich says less permitted development is allowed in Article 4 direction areas, so planning permission may be needed for most works. Replacement windows are an external change. Put the window and door order behind the planning answer in the programme, because frames made to the wrong pattern cannot be sent back.
Renovating a house to let rooms is a separate question. Royal Greenwich's Article 4 direction requiring planning permission to convert a house into an HMO covers the whole borough and came into force on 27 September 2018. A family house in Eltham refitted with extra bathrooms and locks on the bedroom doors, then let room by room to sharers, is the kind of change it catches. Settle the planning position before the layout is drawn, because the bathrooms, fire doors and kitchen size a shared house needs are different from those of a family home.
One team sequencing your Eltham renovation
The value of a whole-house renovation in Eltham comes from proper sequencing. We plan the structural work first, then first-fix electrics and plumbing, followed by plastering, before moving on to the kitchen, bathrooms, second-fix and decoration. Handling it all under one roof means no gaps between trades and no arguments over who does what, which keeps an interwar house project on programme.
Renovating a family home usually means living around the works or moving out for a spell, so we agree a realistic timeline and keep the site tidy and secure throughout. From a single accountable point of contact you get clear updates, transparent pricing and a house that feels rebuilt for the way you live now, while still sitting comfortably among the other period homes of SE9.

FAQ
Frequently Asked Questions about Home Renovation Eltham
What happens to the home renovation price if the scope changes in Eltham?
A scope change on home renovation in Eltham is costed and agreed in writing before it is carried out. If you add to the work at SE9, or the structure of the interwar home needs more than the survey suggested, GS Renovation sets out the effect on price and programme against the original figure within £40,000 to £150,000 or more (indicative). Even a change keeps to the sequence of work: strip-out comes before first fix, and first fix before plaster.
Can you renovate my whole Eltham house while keeping its original features?
Yes. Eltham's interwar houses often have coving, picture rails, fireplaces and panelled doors worth saving. We restore those features while rewiring, replumbing, replastering and reconfiguring the layout behind them. Any structural changes go through a structural engineer and building control. It all runs as one sequenced project across your SE9 home, so trades never clash and the character stays intact.
Should we move out during a full renovation of our Eltham semi?
If the rewire and replumb run through both floors at once, most families find it easier to leave for that phase. Power and water are off for spells, floors are lifted upstairs and down, and dust gets everywhere despite sheeting. Where moving out is not possible, the work can be staged floor by floor, which takes longer overall but keeps one level usable, with one working WC throughout.
Why do the air bricks on an Eltham semi matter during a renovation?
They ventilate the suspended timber ground floor, and the whole floor depends on them. Over the years paths get raised, patios laid and extensions built across them, and the void below goes damp. Before new flooring goes down we clear or extend the ventilation route and check joist ends for rot. It is far easier while the floor is open than after the new boards are laid.
When should the heating system be decided in an Eltham house renovation?
Before first fix, because it sets the pipe routes. A combi boiler frees the airing cupboard but has to cope with every tap and shower you plan; a system boiler with a cylinder needs that cupboard space and different pipework. Underfloor heating downstairs changes things again. Any gas work is done by a Gas Safe registered engineer, and it goes in before the plasterers arrive.
Which parts of an Eltham whole-house renovation need building control notifying?
More than people expect. New circuits and a new consumer unit fall under Part P and are certified by a registered electrician. Removing walls or chimney breasts needs structural approval. New bathroom and kitchen extraction must be ducted outside under Part F, and if you are replastering or dry-lining an outside wall, that thermal element has to meet current Part L insulation standards.
Is there a fee for listed building consent on an Eltham house?
No. Royal Greenwich does not charge a fee for listed building consent applications. The cost of renovating a listed house sits elsewhere: in the drawings and heritage information the application needs, and in the time it takes. Internal work to a listed house, including taking out walls or stripping old plaster, can need consent as well as external work, so the consent is programmed ahead of strip-out rather than alongside it.
Is an Eltham house on the local heritage list treated differently?
Royal Greenwich keeps a local heritage list of buildings of local architectural or historic interest, with over 500 entries. Local listing is not statutory listing and adds no consent of its own for internal work. What it does is flag the character of the house when a planning application is needed for outside changes. Check the list before designing a side extension, a larger porch or other outside work on an Eltham house that needs planning permission.
Is a Royal Greenwich Duty Planner meeting worth booking before an Eltham renovation?
Where the renovation changes the outside of the house, often yes. Royal Greenwich's Duty Planner homeowner service is a paid meeting, with a site visit available at an additional charge. For new windows at an address under an Article 4 direction, or a layout heading towards shared living, a meeting helps settle whether an application is needed before anything is ordered. For internal work to an ordinary house, it adds little.
