Homes in and around Bognor Regis
Bognor Regis grew as a seaside resort, and its housing reflects that history. Victorian and Edwardian terraces and villas sit closer to the town centre and seafront, while inter-war and post-war semi detached houses and a large number of bungalows spread along the coast and inland. Newer estates on the edges of the town add modern family homes to the mix.
Bungalows are a feature of the area, and they raise particular questions for anyone wanting more space. Some have roofs tall enough to take a room upstairs, while others suit a rear or side extension better. Coastal exposure matters too, because homes near the sea take the full force of wind, salt and driving rain.
Bungalow loft conversions
Converting the roof of a bungalow can add one or two bedrooms without losing garden space, which makes it a popular choice where plots are modest. The work often involves a new staircase, which takes space from the ground floor, so the layout needs careful thought. Head height, the roof structure and the position of the stairs all decide whether a conversion is practical.
Price guides differ on what a bungalow loft costs. MyJobQuote gives a figure of £45,000 for a bungalow conversion, while Checkatrade gives an average of £75,000 for a 50m² bungalow loft, within a range of £62,500 to £87,500 and a timescale of 10 to 12 weeks. The gap shows how much size and specification matter, so treat both as guides rather than budgets and compare real quotes. Our loft conversion cost guide covers the other conversion types.
Building near the coast
Homes close to the seafront need materials and details chosen with the weather in mind. Ask builders how they will protect render, pointing and roof coverings from wind driven rain, and what specification they recommend for new windows and external doors. Metal fixings and fittings on the outside of the building are worth discussing too, because salt air can shorten their life.
Large glazed openings are a common request on coastal extensions. Less.co.uk lists bi-fold doors at £3,000 to £6,000 and a roof lantern at £1,500 to £3,500 as extras on top of the basic build cost. A good builder will explain how any large opening will be supported and sealed against the weather.
Planning a rear or side extension
For a bungalow or house that is not in a conservation area, the Planning Portal says a single storey rear extension can project up to four metres from the original rear wall of a detached house, or three metres for any other house, without a planning application. Through the prior approval process, those depths increase to eight metres and six metres, and GOV.UK sets the prior approval fee for a larger rear extension at £249 from 1 April 2026. A full householder application for a single dwellinghouse costs £548.
These rights apply to houses only, not to flats or maisonettes, and they do not cover listed buildings in the same way. Check with Arun District Council before you commit to a design, and never assume permission will be granted. Our extension planning permission guide sets out the process in more detail.
Arun building control charges
Bognor Regis is in Arun district, and Arun District Council publishes its building control charges with effect from 1 April 2026. Some of the main domestic charges are shown below. Arun states that full plan, building notice and additional fees require 20% VAT, so these figures are shown before VAT, and regularisation is not subject to VAT.

| Extension up to 15m² | £266.75 | £640.20 | £1,088.34 | Arun District Council |

| Integral garage to habitable room | £266.75 | £586.85 | £1,024.32 | Arun District Council |
You can also use a private registered building control approver, which sets its own fee. Either way, your builder should know which route suits the project.

Frequently asked questions
Can I add a room in the roof of my bungalow?+
Often you can, but it depends on the roof height, the structure and where a staircase can go. A builder or designer can assess this on a site visit. If the roof needs to be raised or reshaped, planning permission is more likely to be needed.
How much does a bungalow loft conversion cost?+
MyJobQuote gives £45,000 for a bungalow conversion, while Checkatrade gives an average of £75,000 for a 50m² bungalow loft. The figures differ because of size and specification, so compare quotes for your own home.
What does Arun charge for building control on an extension?+
For an extension up to 60m², Arun's charges from 1 April 2026 are £346.78 for the full plan charge and £853.60 for the inspection charge, or £1,440.45 by building notice. Arun states that these fees require 20% VAT, so they are shown before VAT.
Do I need planning permission for a single storey rear extension?+
Not always. The Planning Portal allows up to four metres on a detached house and three metres on other houses under permitted development, with larger depths possible through prior approval. Check with Arun District Council, as rules differ for flats, listed buildings and conservation areas.
