Hampstead

Hampstead houses are beautiful but they were not designed for the way people live now. Open kitchens, proper bathrooms, home offices, more light - we help homeowners in NW3 get those things without losing what makes the house special in the first place.

What We Do in Hampstead

Extensions, loft conversions and renovations for period homes

Most of the properties we work on in Hampstead are Victorian or Edwardian houses, often in conservation areas. They tend to share the same issues - dark kitchens, small bathrooms, unused loft space, gardens you can not really connect to from the ground floor.

A well-designed rear extension with proper glazing can completely change how the ground floor works. A loft conversion adds a bedroom and bathroom without touching the footprint. And a basement, which many Hampstead houses can accommodate, gives you a whole new floor.

We understand the constraints that come with working in this part of London. Camden Council's planning team is familiar to us, we know what they tend to approve and where the boundaries are, and we design accordingly.

  • Rear and side return extensions
  • Loft conversions - dormer and mansard
  • Basement conversions and excavations
  • Full house renovations
  • Interior design and specification
  • Planning applications and listed building consent

Local Knowledge

We know Hampstead and we know Camden

Hampstead is one of the most architecturally sensitive areas in London. Large parts fall within conservation areas, and there are a significant number of listed buildings. That does not mean you can not do anything - it just means you need an architect who understands the rules and designs within them.

We have worked on projects across NW3 and the surrounding areas including Belsize Park, Highgate, Gospel Oak and Swiss Cottage. Each has its own planning quirks, and knowing those quirks matters when you are trying to get something approved.

Camden Council generally responds well to contemporary rear extensions that sit clearly as new additions rather than trying to mimic the original building. They are also receptive to well-designed loft conversions, particularly mansard extensions to the rear where they are not visible from the street.

As an architecture and construction studio, we manage the entire project in-house - from the initial design through planning permission and building regulations to the actual build. One team, one contract, one point of contact.

Common Questions

Architecture in Hampstead - answered

Do I need planning permission for an extension in Hampstead? +
Hampstead has several conservation areas and includes properties within the Hampstead Conservation Area, one of the largest in London. If your property falls within a conservation area, permitted development rights are more restricted and you will likely need planning permission for any extension. Even outside conservation areas, larger extensions will need a full application. Rosace checks the planning position at the start of every project so you know exactly where you stand.
How much does a house extension cost in Hampstead? +
Construction costs in Hampstead tend to be higher than the London average, typically £3,000 to £4,500 per square metre, due to the quality of finishes expected, the complexity of period properties and access constraints on many Hampstead streets. A rear extension might cost between £100,000 and £200,000 depending on size and specification.
Can I convert the loft in my Hampstead house? +
In most cases, yes. Victorian and Edwardian houses in Hampstead often have generous roof spaces that suit dormer or mansard conversions. However, if the property is in a conservation area, a mansard extension to the rear is usually the most acceptable option for planners. We work closely with Camden Council on loft conversion applications in Hampstead and know what they are likely to approve.
Does Rosace work with listed buildings in Hampstead? +
Yes. Hampstead has a significant number of listed buildings and we have experience working within the listed building consent process. Any alterations to a listed building require separate listed building consent in addition to planning permission. We work with heritage consultants where needed to prepare the right supporting documents.
