FAQ

Questions,answered.

The questions we are asked most often, answered plainly. If yours is not here, ask us.

Working with us

Which areas do you work in?

We work across Bristol, Bath, Somerset, Devon, Newport and South Wales.

What happens at the first consultation?

We visit the property, listen to your brief, discuss budget and timing, and explain the likely planning route. Afterwards we send a written fee proposal.

How are your fees structured?

We provide a fixed fee for each stage of work, set out in a written proposal before you commit. You can pause between stages.

Are you an architect?

NDB Architecture is an architectural design studio. We are not registered with the Architects Registration Board, so we do not use the title architect, which is protected in the UK. We design homes, prepare planning and building regulations drawings and coordinate engineers and other consultants.

Do you help find a builder?

Yes. We prepare tender documents, recommend suitable contractors, compare their prices and help you appoint one. We can also administer the building contract on site.

Can you work with my existing drawings or builder?

Often, yes. We review what exists and advise whether it can be developed or needs to be redrawn.

House extensions

Do I need an architect for a house extension in Bristol?

It is not a legal requirement. You can use an ARB-registered architect or an architectural designer. Either way, a good designer will usually find a better layout, a clearer planning route and a more complete set of drawings for your builder. On constrained sites, conservation areas or period houses, that difference is significant.

How long does planning permission take for an extension in Bristol?

Householder applications have a statutory target of eight weeks from validation. Allow a little longer in conservation areas or where amendments are requested. A Lawful Development Certificate has the same target.

Can I extend under permitted development in a conservation area?

Single-storey rear extensions are often still possible, but side extensions and certain materials are restricted, and some Bristol streets have Article 4 directions. We check this for your specific address before design begins.

Will I need a party wall agreement?

If you share a wall with a neighbour or will excavate near their foundations, the Party Wall Act will almost certainly apply. We prepare the information needed for notices and coordinate with surveyors if required.

Loft conversions

Do I need planning permission for a loft conversion in Bristol?

Often not, if the house is outside a conservation area and the work stays within permitted development limits. Flats always need permission. We recommend a Lawful Development Certificate either way, so the position is recorded.

What is the minimum head height for a loft conversion?

There is no single legal minimum for rooms, but a practical guide is around 2.2 metres from the top of the ceiling joists to the ridge before conversion. The stair needs 2 metres of headroom, with some relaxation for loft stairs.

Can you convert a barn in Somerset?

Frequently, yes. The route depends on the building, its use and its location. Class Q prior approval, full planning and listed building consent each have different requirements. A short feasibility study identifies the right route.

Will I need to move out during a loft conversion?

Usually not. Most of the work happens in the roof, with access often from scaffolding. The disruption comes when the new stair is formed, which is normally a short period near the end of the build.

Full renovations

Do I need listed building consent for internal changes?

Yes, if the work affects the special architectural or historic interest of the building. That includes many internal alterations. We assess this with you and prepare the heritage statement needed for the application.

Can I install double glazing in a listed house in Bath?

Replacement of historic windows is usually resisted. Slim double glazing in new sashes is sometimes accepted where the existing windows are not original. Secondary glazing is often the most acceptable route.

How do you control cost on a renovation?

By finding problems early. Thorough surveys, a complete specification and a competitive tender reduce unknowns. We also recommend a contingency for old buildings, as some conditions only appear once work begins.

New build homes

Read the full guide

Can I build a new house in the countryside?

Only in limited circumstances, such as replacing an existing dwelling, converting a building or meeting the high bar for exceptional design. A site appraisal will tell you which route, if any, is realistic.

Should I speak to a designer before buying a plot?

Yes. A short appraisal before purchase can reveal planning, access or ground issues that change the value of the land. It is far cheaper than discovering them afterwards.

Do you work on new builds in Wales?

Yes. We work in Newport, Monmouthshire and across South Wales under Welsh planning policy and building regulations, which differ from England in several respects.

Planning and building regulations drawings

Read the full guide

How much do planning drawings cost?

It depends on the size and complexity of the property and the number of drawings required. After a short call and site visit we send a fixed fee proposal, broken into stages, so you know the cost before committing.

What is the difference between planning and building regulations?

Planning controls what is built and how it looks in its context. Building regulations control how it is built: structure, fire safety, insulation and drainage. Most projects need building regulations approval even when planning is not required.

Can you submit to councils outside Bristol?

Yes. We regularly submit to Bath and North East Somerset, Somerset Council, the Devon district councils, the National Park authorities, Newport City Council and Monmouthshire.
