How to Restore or Renovate an Old Dolls House: Where to Start

1. Do not strip anything yet.
2. Photograph the entire house.
3. Record dimensions, labels and construction details.
4. Remove loose modern furniture carefully.
5. Identify the maker/date if possible.
6. Assess structure, damp, pests, wiring and finishes.
7. Decide whether the house is a renovation project or a conservation-sensitive object.
8. Stabilise structural problems.
9. Plan wiring before new wallpaper/floors.
10. Work from least destructive to most destructive.
11. Keep samples and removed original parts.
12. Document every change.

Take photographs of:

• front;
• back;
• sides;
• roof;
• base;
• every room;
• wallpaper;
• flooring;
• windows;
• doors;
• hinges;
• electrical components;
• labels;
• stamps;
• handwritten notes;
• unusual construction.

Take close-ups and wide views.

These images become your baseline record.

Before cleaning or sanding, inspect hidden areas.

Possible clues include:

• manufacturer's labels;
• stamps;
• pencilled dates;
• retailer labels;
• instruction fragments;
• distinctive hinges;
• characteristic windows;
• original packaging.

Photograph them before cleaning.

Do not sand away a stamp or handwritten note.

Measure:

• overall width/height/depth;
• room dimensions;
• door heights;
• ceiling heights;
• wall thickness;
• base thickness.

These measurements can help identify the scale and sometimes distinguish between manufacturers or kit versions.

See How to Tell What Scale Your Dolls House Is.

Remove loose modern furniture if it can be lifted safely.

But do not automatically remove:

• original fitted furniture;
• glued carpets;
• old curtains;
• wallpaper fragments;
• electrical fittings;
• built-in fireplaces.

An object that looks untidy may be part of the house's history.

Bag and label loose pieces by room.

Renovation

You may choose to:

• repaint;
• replace wallpaper;
• modernise rooms;
• install new flooring;
• replace damaged trim;
• change the lighting.

Conservation

The aim is to preserve significant original material.

That may mean:

• retaining faded wallpaper;
• stabilising rather than replacing;
• preserving old repairs;
• cleaning minimally;
• using reversible materials.

Professional conservation often values evidence of an object's life rather than making it look new.

National Trust dolls-house conservation projects demonstrate this approach: specialists preserve original paper, textiles, furniture and previous interventions where they contribute to the object's history.

Pause before irreversible work if the house appears:

• very old;
• unusually finely made;
• labelled by a known maker;
• associated with a documented family history;
• furnished with original period contents;
• substantially original in wallpaper/paint;
• potentially valuable.

A specialist dolls-house collector, auction specialist or accredited conservator may be able to identify what you have.

Do not rely solely on an online price listing.

Check:

• base flatness;
• loose walls;
• roof movement;
• delamination;
• broken joints;
• loose hinges;
• missing supports;
• cracks;
• water damage.

Do not decorate around an unstable structure.

Structural stabilisation comes first.

Look for:

• staining;
• musty smell;
• swollen MDF;
• warped timber;
• visible mould.

Do not seal active damp beneath new finishes.

Address the environmental cause first.

Historic or fragile objects with mould may require professional conservation handling.

Inspect timber, textiles and paper for signs of pests.

Look for:

• holes;
• frass/dust;
• webbing;
• insect cases;
• textile loss.

Isolate a suspected infested object from other collections until it can be properly assessed.

Older houses may contain:

• tape wire;
• round wire;
• old transformers;
• improvised connections;
• non-functioning lamps.

Do not automatically energise an unknown old system.

Inspect it first.

If the mains-side equipment is old, damaged or uncertain, do not use it.

Modern battery lighting can be an alternative where rewiring would damage original finishes.

Dirt can make a finish look much worse than it actually is.

Start conservatively.

For an ordinary modern house, a soft brush and controlled surface cleaning may reveal what can be retained.

For fragile historic materials, cleaning itself can cause damage.

Professional conservation case studies use material-specific techniques such as low-suction vacuuming, soft brushes and specialist sponges—not household scrubbing.

Do not copy wet-cleaning treatments from museum case studies without the relevant expertise; museum conservators test materials and use controlled methods.

MDF is vulnerable to moisture.

Excess water can cause:

• swelling;
• raised fibres;
• edge damage;
• distortion.

When removing modern wallpaper from MDF, use the minimum moisture necessary and work gradually.

If you decide an ordinary renovation genuinely requires removal, retain labelled samples of:

• wallpaper;
• flooring;
• paint colours;
• trim;
• fabric.

Photograph them in place first.

This preserves a record and can help with future matching.

A modern renovation often works in reverse of a new build.

If wallpaper runs beneath trim, remove the trim carefully before stripping the wall.

Keep parts as templates even if they will later be replaced.

Label every piece.

Once the house is assessed and documentation is complete:

• repair loose joints;
• replace structurally necessary missing material;
• fill inappropriate holes where justified;
• stabilise floors;
• correct doors/hinges.

Do not use decorative finishes to conceal unresolved movement.

If adding a new concealed system:

1. decide fixture locations;
2. choose the system;
3. route wiring;
4. test;
5. photograph;
6. only then install new wallpaper and flooring.

See How to Plan Dolls House Wiring Before Decorating.

You do not have to replace everything that shows age.

Original features may include:

• wallpaper;
• paint;
• floor coverings;
• fireplaces;
• windows;
• door furniture;
• staircases;
• mouldings.

Ask whether the ageing is:

• harmless patina;
• active deterioration;
• structural damage;
• simply not to your taste.

Those are different problems.

Where possible, use methods that can be removed later.

Examples:

• removable floor panels;
• freestanding room inserts;
• battery lights;
• removable furniture;
• minimally invasive fixings.

This is particularly valuable when you want to enjoy an older house without permanently erasing its previous state.

For an ordinary renovation:

• stabilise the wall;
• remove loose residue;
• repair defects;
• seal the surface;
• install/test wiring;
• apply new paper;
• refit trim.

If original wallpaper is historically significant, do not automatically remove it.

National Trust conservation of Beatrix Potter's dolls house included repair of torn wallpaper rather than wholesale replacement, illustrating the difference between conservation and redecoration.

Before lifting old flooring, determine whether it is original.

If replacing modern damaged material:

• make a pattern;
• inspect wiring beneath it;
• prepare the substrate;
• consider a removable replacement.

Retain any useful original template.

Doors and windows may be among the first parts removed during a renovation if they sit over siding or wallpaper, but they may be historically significant.

Photograph:

• hinges;
• frame construction;
• glazing;
• trim profiles.

Avoid throwing away damaged originals until replacements are fitted and documented.

Do not attack old adhesive blindly with solvent.

You may not know:

• the adhesive chemistry;
• the substrate;
• the paint underneath;
• whether the solvent will stain.

Start mechanically and conservatively where safe, and test in hidden areas.

Historically important objects may need professional treatment.

Older painted objects can potentially contain hazardous pigments, including lead.

Do not dry-sand unidentified old paint and create airborne dust.

If the age/composition is uncertain, take a cautious approach and obtain appropriate specialist advice/testing.

Miniature furniture, carpets, curtains and dolls can be more fragile than the house itself.

Do not assume that:

• upholstery can be washed;
• old silk can be handled repeatedly;
• wood furniture should be polished;
• metal should be aggressively cleaned.

National Trust dolls-house projects use textile, object and paper conservators separately because different materials need different treatment.

An old repair may be ugly but historically informative.

Before removing it:

• photograph it;
• determine whether it is causing damage;
• consider whether it tells part of the object's story.

Professional conservation sometimes retains earlier interventions for precisely this reason.

If conservation concerns have been ruled out:

1. document;
2. empty rooms;
3. remove obstructing trim;
4. remove failed modern finishes;
5. repair structure;
6. prepare surfaces;
7. plan/install/test wiring;
8. finish ceilings;
9. wallpaper/paint walls;
10. install flooring;
11. refit stairs;
12. fit trim;
13. install lighting;
14. clean;
15. furnish and style.

For a potentially important house:

1. document;
2. identify;
3. research provenance;
4. condition-assess;
5. consult specialist advice where warranted;
6. stabilise urgent deterioration;
7. clean minimally and appropriately;
8. repair using compatible/reversible methods;
9. preserve original finishes where possible;
10. improve display/storage conditions;
11. document treatment.

The aim is preservation, not making the house look new.

Protect the finished house from:

• direct sunlight;
• excessive humidity;
• damp;
• dust;
• unstable temperature;
• rough handling.

A transparent cover or display case can dramatically reduce dust load.

Avoid placing valuable miniatures where strong sunlight will fade textiles and paper.

Keep:

• before photos;
• after photos;
• measurements;
• provenance;
• manufacturer identification;
• materials removed;
• materials added;
• paint references;
• wallpaper samples;
• wiring diagram;
• adhesive information;
• date of work.

Future owners will thank you.

Stripping before identifying

Original evidence can disappear.

Sanding old paint without assessing it

Historic coatings can be hazardous and significant.

Using lots of water on MDF

The substrate can swell.

Applying power to unknown wiring

Old equipment may be unsafe.

Replacing everything because it looks old

Age is not automatically damage.

Throwing away original pieces

Even broken material can be valuable as evidence or a template.

Treating conservation as decoration

Their goals are different.

• ☐ Full photographic record
• ☐ Labels/marks photographed
• ☐ Dimensions recorded
• ☐ Scale assessed
• ☐ Maker/date researched
• ☐ Provenance recorded
• ☐ Structure assessed
• ☐ Moisture/mould checked
• ☐ Pest signs checked
• ☐ Wiring assessed before powering
• ☐ Original finishes identified
• ☐ Conservation significance considered
• ☐ Removed material labelled and retained where appropriate
• ☐ New wiring completed before new finishes
• ☐ Treatment record maintained

Identify and document before you strip. Stabilise before you decorate. Preserve before you replace when original material matters.

A renovation can make an ordinary dolls house your own.

A conservation project protects the story already contained in the object.

Knowing which one you are doing is the most important first decision.
