Looking for builders in New Milton? Ring 07435 839745 or send the form.

Looking for a builder for the whole job? Builders in New Milton sets out every trade we take on in New Milton, how to choose a builder and how pricing works.

The house may be a good one that has become too small, with a garden that could take a room at the back. The garden wall may have started to lean. Or a bungalow roof, a flat roof over the garage, or render on a gable end may have reached the point where patching no longer makes sense.

We are a building and roofing company in Boscombe. New Milton has a BH postcode but sits in Hampshire, so planning goes to New Forest District Council, not BCP. Every stage of a building job sits on one written itemised quote, and you have one person to ring.

What we build

What we build and repair in New Milton

Nearly half the homes around the town centre were built between 1945 and 1982: semis, detached houses and bungalows. That shapes the building work here more than anything else.

Extending a post-war house

The usual shape is a single-storey room across the back, opening the kitchen into the garden. We dig and pour the footings, get them passed by building control, lay the floor, build the walls in block with brick or render to match, fit a steel where the back wall opens, then roof, plaster and floor. It takes several weeks on site for a plain one. We will talk you out of it if the extra room would leave the middle of the house dark, or if moving the kitchen within the house gets you most of what you want for less.

Extending a bungalow

Bungalows extend well at the back or the side, because there is no first floor to support and the new roof can follow the old. The detail that matters is the roof line: a low-pitched bungalow roof has to meet the extension roof without a gutter trapped between them.

Brick walls and repairs

Front and garden walls, piers, steps and retaining walls, built new or rebuilt where they have leaned. We also repair cracked brickwork where a lintel or corner has moved, and match the brick to what is there. A wall is days, not weeks. See brickwork and repointing in New Milton.

Plaster and render

Plastering new rooms and skimming tired ones, and rendering an extension so it sits with the house. A blown or cracked patch of render is worth catching early, before water gets in behind it. More on plastering in New Milton and rendering in New Milton.

Kitchens, drives and drainage

Kitchen fitting from strip-out to worktops, with the walls and floor sorted first; our kitchen fitting page covers how it runs. Outside, driveways, patios, channel drains and soakaways, with the soakaway tested before it takes the water off a new roof. See driveways and patios in New Milton.

Roofing, and roofers in New Milton

Re-roofs and repairs in tile and slate, flat roofs in EPDM, GRP and felt, lead flashings, and dry-fix ridges and verges on the more exposed roofs toward Barton. By the time bungalow tiles are tired, the battens and underlay under them may be too, and we will show you what we find. When the roof is the whole job, our page for roofers in New Milton goes into it properly.

Water coming in now? Ring 07435 839745. Scheduled work Mon to Fri, 8am to 6pm. Something urgent? Ring, and if we miss you we call back.

Where the two jobs meet

What goes on top of the extension

An extension on a post-war semi or a bungalow usually gets one of two roofs. A flat roof in EPDM or GRP keeps the height down, takes roof lights well and suits a room under an upstairs window. A pitched roof in tile to match costs more in timber, but it can look as though it was always part of the house.

Whichever you choose, the join between new roof and old wall is where extensions leak, and it needs a lead flashing or cavity tray dressed in properly. The new wall and the roof above it are both lines on one written quote. Compare coverings on flat roofing in New Milton or in GRP, EPDM or felt.

Permission

Planning and approvals in New Milton

New Forest District Council handles planning for the town. The New Forest National Park boundary runs to the north, and Bashley and Tiptoe are inside it, but the town, Barton on Sea and Ashley are not.

Planning permission. A single-storey rear extension on a house often needs no application if it stays within the permitted development limits: 3 metres beyond the original rear wall of a semi or terrace, 4 metres for a detached house, and no taller than 4 metres. Two-storey and side extensions have tighter rules. Old Milton Green is a conservation area, and inside it a side extension or a rear extension of more than one storey always needs an application.

Building Regulations. Needed with or without planning. Building control checks the foundations, structure, drainage and insulation as the job goes up. See Regulation 12 and Approved Document A.

The neighbours. Work on the boundary, or foundations dug within 3 metres of a neighbour's building and deeper than theirs, needs notice under the Party Wall Act at least a month before it starts.

How we work

How the job runs when we are your builder

  • Thomas Hannen visits for free, prices the work himself, and is the one person you deal with.
  • The written quote is free and itemised: groundwork, walls, roof, plaster and finishes each on its own line.
  • Scaffold goes up when the job calls for it, shown as its own line.
  • Nothing is left open overnight. Openings in the roof or walls are sheeted and weathered at the end of every day.
  • The site is swept each day, and the waste goes away with us.
  • If something turns up that the visit could not show, we stop, photograph it and price it in writing first.

Scheduled work Mon to Fri, 8am to 6pm. See how we price a job.

Price

What sets the price of building work here

  • The ground. How deep the footings have to go, and whether roots or drains are in the way. Building control confirms it once the trench is dug.
  • Access. Space for a skip and a small digger on the drive, or none.
  • The roof. Flat or pitched, and whether tiles have to match the house.
  • Matching the walls. Brick to match, or render that meets the old coat without a visible line.
  • Drainage. Where the roof water goes, and whether a drain or manhole has to move.
  • Structure. Any steel over a new opening, sized by an engineer.
  • Finishes. Where the job ends: plastered shell or finished room.

Keeping an extension on budget comes down to deciding the finishes before work starts, not changing the design once walls are up, and reading any provisional items on the quote. With any builder's quote, check it is itemised, ask who will be on site, and ask how extras are agreed. Citizens Advice lists what to check before building work starts.

New Milton

On the cliff top at Barton, check the shoreline plan before you extend

The Environment Agency's shoreline planning map sets the policy for the stretch called Barton-on-Sea Marine Drive and Marine Drive West as managed realignment through to 2105. That means measures that might slow erosion of the cliffs, not stop it. The action plan for that stretch also says to work with communities on a plan for the loss of properties at its western end. Its erosion projections are guidance, and it says itself that they do not give information for individual properties.

If your house is on a cliff-top plot near Marine Drive, look up the stretch and its projections, and ask New Forest District Council what it would accept, before spending money on drawings for an extension. Ask building control too where the roof water from a new extension should go, because a soakaway near an eroding cliff is not a decision to guess at. Further back from the cliff, and across the rest of New Milton, none of this applies.

Reviews

What customers said

Two hard-landscaping jobs, a driveway and a patio, in the customers' own words. The driveway was a complex job with regular updates, and the patio customer was pleased with how it turned out.

…The job was quite complex and far from straightforward, but they handled everything with professionalism and skill. They were quick, efficient, friendly, and kept us updated throughout the whole process with excellent communication…

Really happy with our new patio from Bournemouth Roofing & Building. It looks beautiful and we couldn't be more pleased with how it's turned out. Tom and Lloyd were both lovely, really knowledgeable and kept us updated throughout, which was reassuring…

Questions

Questions about building work in New Milton

Do you work in New Milton, even though it is in Hampshire?

Yes. New Milton, Old Milton, Barton on Sea, Ashley, Bashley, Becton, Walkford and Tiptoe are all inside our normal working area, across the BH25 postcodes. The BH prefix is Bournemouth's, but planning here is New Forest District Council, or the National Park Authority for the few addresses inside the Park. Tell us the street when you ring and we will check which applies.

How do I keep an extension on budget?

Settle what you want before the first trench is dug: the size, the roof, the doors and the finishes. Changes once the walls are up cost the most. Read the quote for provisional items, the parts nobody can price until the ground is open, and keep some money back for them. And compare quotes line by line, not by the total at the bottom.

How do you quote for an extension?

The whole build goes on one written itemised quote, from the footings through the walls and roof to the plaster, with each stage on its own line and one person to ring. Anything that needs a specialist sign-off, such as an engineer's calculation for a steel beam, is listed separately too.

Can you build an extension through the winter?

Much of it, yes. Groundworks and blockwork carry on in most weather, but mortar and render should not go on in frost, and a roof waits for a dry spell. We plan the stages so the building is weathertight as early as possible, and we tell you if the weather is likely to move the dates.

Is my New Milton house in the New Forest National Park?

Almost certainly not if you are in the town, Barton on Sea or Ashley. Bashley, north of the town, and Tiptoe are inside the Park, where the rules for extensions are much tighter and the National Park Authority decides. The Park's interactive property map shows which side of the line an address falls.

How long does an extension take once work starts?

Several weeks on site for a single-storey rear extension, longer for two storeys or where the drains or the ground need more work. Drawings, building control and any planning come first and can take longer than the build. The quote sets the stages out in order.
