Greenwich and South East London
More space, without leaving the neighbourhood.
Greenwich homes range from compact Victorian terraces to later semi-detached houses, each with a different roof, access and planning context. Meridian takes the approved design and turns it into a finished room, coordinating structure, roofing, services, stairs and decoration.
Loft conversion types for Greenwich homes
The best conversion is the one that fits the roof, the street and the way you want to use the room.
Hip-to-gable
Extends a sloping side roof into a vertical gable, often unlocking a larger, more usable plan in end terraces and semi-detached homes.
Mansard
Rebuilds the rear roof slope for maximum space. Particularly relevant to some London roof forms and normally subject to planning approval.
Rooflight conversion
Works within the existing roof shape where headroom is already good, keeping the exterior intervention and structural work more contained.
Plan around Greenwich rules before the build.
National permitted development rights can cover some house loft extensions, but they do not apply in every situation. Greenwich also contains conservation areas and Article 4 direction areas where extra controls may apply.

Do loft conversions in Greenwich need planning permission?
Some houses can use permitted development rights, subject to national limits and local restrictions. Conservation areas, listed buildings and Article 4 directions can change what is allowed. Ask your architect or Royal Greenwich planning team to confirm the route for your address before building starts.
Which loft conversion works best for a Greenwich terrace?
A rear dormer is often the most efficient way to add usable floor area and headroom to a terraced house. A mansard can create more space but usually needs planning permission. The roof shape, street context and local design controls determine the right solution.
How long does a Greenwich loft conversion take?
A typical dormer build usually takes around 8 to 10 weeks on site. Hip-to-gable and mansard projects can take 10 to 14 weeks, depending on structure, access and finish. Your programme should be agreed against the final drawings before work begins.
Can we stay at home during the build?
Usually, yes. Where the roof and access allow, the working area can be separated from the home and reached externally for much of the build. The new staircase is commonly opened through later in the programme.
What do you need to prepare a quote?
Send the architect's drawings, structural calculations and your Greenwich postcode. These let us price the specified structure, roofing, services and finish as an itemised build rather than a broad estimate.
