We are considering buying this 1930s semi and would appreciate advice on improving the ground-floor layout while keeping costs as low as reasonably possible.

The current kitchen is approximately 8'11" × 8'1", so it feels quite small. I have attached the existing floor plan and two examples from similar houses:

• Option 1: Remove the wall between the kitchen and dining room.
• Option 2: Extend the kitchen towards the rear.

We would also like to add a downstairs toilet, potentially beneath or beside the stairs if the plumbing and headroom allow.

Option 1: Open the kitchen into the dining room

Our first idea is to remove the wall between the kitchen and dining room to create an open-plan space. We suspect this wall may be load-bearing.

We could then:

• Close the doorway between the hallway and kitchen
• Close the doorway between the kitchen and garage
• Install a U-shaped kitchen within roughly the existing kitchen footprint
• Use the rest of the room as an open dining and living space

Would closing the two doorways provide enough uninterrupted wall space for a practical kitchen, or would the kitchen still feel cramped?

Option 2: Extend the kitchen towards the rear

The alternative is to remove the rear kitchen wall and extend the kitchen slightly into the garden.

If we are already paying for structural work, we are wondering whether it would make more sense to extend the kitchen rather than only remove the internal wall. The extension could add useful floor area and might allow us to retain the existing entrance between the kitchen and garage.

However, it would also require foundations, a new roof, drainage considerations and Building Regulations approval. We are unsure whether a relatively small extension would add enough usable space to justify the additional cost.

Possible garage conversion

In the future, we may want to convert the garage into a bedroom with an ensuite. It could be used as a guest bedroom or potentially rented to a lodger.

The garage is approximately 24'6" × 9'6", but it is currently a very basic structure. It appears to have thin, bare walls, probably a concrete floor or slab, and the garage roof is in poor condition. It would likely need substantial insulation, damp-proofing, flooring, heating, ventilation, windows, drainage and roof work before it could become a habitable room.

We are considering creating its entrance from the hallway near the front door, beside the staircase. This could give the room some separation from the main living area.

Garden access

We are also considering replacing the dining-room window facing the garden with doors, but we have not decided what type would work best.

The possibilities we have considered are:

• French doors
• Sliding patio doors
• Bifold doors
• A single glazed door with a fixed window
• Retaining the existing window and creating garden access elsewhere

We do not necessarily need the widest possible opening. Our priority is a reasonably priced solution that provides good light and convenient garden access without taking away too much internal or external space.

Our main questions

1. Which kitchen layout would you choose?

Would you remove the wall between the kitchen and dining room and keep the kitchen within its current footprint, or build a small rear extension? Is there a simpler or less expensive layout we have overlooked?

2. Is converting this garage into an ensuite guest room or lodger’s room sensible?

Considering its narrow width, thin bare walls, likely concrete base and poor roof, would conversion be financially and practically worthwhile, or could it cost almost as much as rebuilding it properly? Would the proposed hallway entrance work, and what fire-safety, privacy, sound-insulation, planning or Building Regulations issues should we consider?

3. What should we do about garden access?

Are there practical alternatives to replacing the dining-room window with doors? If doors are the best option, would you choose French, sliding, bifold or a single glazed door with a fixed window? Which option offers the best balance of installation cost, insulation, security, natural light and usable space?

Rough cost comparisons and experiences from anyone who has renovated a similar 1930s house would be especially helpful.

Hi everyone,

We are first-time buyers considering a 1930s three-bedroom semi-detached house in south east outer London. It has been rented out for a long time, and we are concerned that some essential maintenance may have been deferred.

I have attached photos of the relevant areas.

Our main concerns are:

• Roof: It could potentially be the original 1930s roof. We have not yet inspected the loft. There is no known active leak as per the seller, but the roof, chimney and flashings appear aged. Can a roof of this age remain serviceable, or should we budget for replacement soon?
• Electrics: We understand that much of the wiring may be around 40 years old. The seller has provided an EICR, but we will have it reviewed independently. Could wiring of this age remain safe for many more years if the EICR is satisfactory, or is a rewire likely in the foreseeable future?
• Possible damp: There was reportedly slight damp in one of the bedrooms (attached images but they might show it less severe as the listings have AI treated them usually), and there is some mould on the bathroom ceiling. This is also the only wall in the house which has wallpaper and it is slightly yellowish and peeling from edges. We are also worried that it might not be showing up much right now because of the hot and dry weather but could become worse in rain. The owner believes it was caused by condensation, but this was only an assumption. Part of the external wall near that bedroom has perhaps also been repointed, although we do not know whether this was related.
• Boiler: It is believed to be approximately 14 years old, and we are asking for its service history.

The house also needs ground floor flooring, decorating and probably a new kitchen, but we can budget for those. Our concern is discovering expensive essential work involving the roof, wiring, damp, drainage or structure after moving in.

We plan to arrange a RICS Level 3 building survey, ensure the loft is inspected.

For anyone experienced with older houses or former rental properties:

1. How concerning is a potentially original 1930s roof if it is not currently leaking?
2. Is 40-year-old wiring likely to need replacing soon, even if the EICR is satisfactory?
3. Does the reported damp and bathroom mould sound consistent with condensation, or should we be concerned about water ingress or another underlying cause?
4. What should we ask the surveyor to inspect specifically? What can we do other than L3 survey? I have noticed the surveyors just mention that there is dampness and ask to do further investigation which doesn't really help as they don't have the permission to raise flooring/carpets or peel wallpaper etc.
5. Are there any other major issues commonly missed in houses of this age?
6. Would you arrange any additional inspections before buying?

I understand that nobody can diagnose the property conclusively from a few photographs, but it would be helpful to know what experienced homeowners, builders, surveyors and electricians would investigate.

Thanks in advance for any honest advice.
