Bathrooms in Radlett's pre war houses
They were not planned around the fittings people want now, because of when the houses went up. Residential development in Radlett began in the 1890s, when the Kendals, Newberries and Aldenham Lodge estates started selling land. The Aldenham Lodge estate was sold in 1910 and the Newberries estate in 1935. The bathrooms in houses of that generation were fitted into whatever space was left over once the bedrooms were set out.
The original houses on Loom Lane share an Arts and Crafts influenced form of two storeys in brick and tile construction, with gables, chimneys, traditional glazing and pitched roofs. In a house built that way the floor is timber joists spanning onto solid masonry. Moving a soil stack, or forming a level access shower, means notching and trimming that the joists were never sized to take. We survey the floor structure before a layout is agreed, and bring the engineer in where trimming affects a load path.
Housing in Radlett
Take the 3,500 or so homes the valuation list gives Radlett: 24% flats, 76% houses, 12% from before 1919, 19% interwar and 67% post-war. A detached house in Radlett can add a soil stack for an en suite, and 47% of homes here are detached.
Water, damp and the ground below a Radlett bathroom
Water is the local theme here, and it starts below the floor. Public consultation on the Radlett (South) Conservation Area Appraisal raised concerns about minimal foundations on older properties, clay soil and underground water courses. It asked that proposals involving basements be assessed for their effect on adjoining properties, for example through groundwater flow assessments. Those same conditions shape how a ground floor wet room is detailed.
Radlett lies in the valley of Tykes Water, a stream that runs north from Aldenham Reservoir to the River Colne. The village centre and train station sit in a relatively narrow valley, rising from about 200 feet to 400 feet above sea level. On sloping ground the falls, the tanking and the drainage runs have to be resolved at design stage rather than improvised on site. We set them out on paper, then build to that, because a shower tray laid to the wrong fall is not something tiling can rescue.
Putting a bathroom in a Radlett loft
A loft bathroom stays available even on the bungalows covered by the Article 4 Directions. Hertsmere Borough Council states that those Directions do not affect conventional loft conversions, including adding rooflights and dormer windows, and that such work can still be carried out without a planning application, subject to the relevant permitted development legislation.
What the Directions do stop is going up a full storey. The council states that owners of the bungalows covered need planning permission to add an extra storey, whether for extra living space or to create another self contained residential unit at first floor level. A dormer with a shower room inside it and a new first floor are two different proposals with two different consent routes. We settle which one you are asking for before anything is priced or drawn.

FAQ
Frequently Asked Questions about Bathroom Renovation Radlett
What is included in your bathroom renovation price in Radlett?
The bathroom renovation price for a Radlett home is itemised as labour, materials, approvals and reinstatement, typically totalling £6,000 to £20,000 or more (London-derived). Where a floor or wall needs structural work, GS Renovation appoints and coordinates the engineer and builds to their specification at WD7. Any Hertfordshire Building Control fee has its own line, and the lines follow the order of works: any underfloor heating is laid and tested before the floor is tiled.
Can a new soil pipe run up the front of a house in a Radlett conservation area?
No, not without permission. Inside Radlett (North) and Radlett (South), a soil vent pipe cannot be added under permitted development to a wall or roof slope forming the front of the house and facing a highway. The routes are to run the stack internally to the existing drain, to take it up a rear or flank elevation, or to apply for permission. We settle which one before the bathroom layout is agreed.
Does adding a downstairs toilet under the stairs need building control approval?
Yes. New drainage, a new soil connection and the ventilation of the room are all inspected under the Building Regulations, and Hertfordshire Building Control handles that for Radlett addresses. The room needs mechanical extract where there is no openable window, and the door swing and layout have to leave usable space. Where the waste runs to a stack on the far side of the house, the fall and the boxing are planned before stud walls go up.
Will a new shower run properly on the higher ground above the village?
That is measured before anything is specified. Radlett rises from about 200 feet to 400 feet above sea level, with the village centre and station in the valley bottom. Incoming pressure and flow at the stopcock vary with height and with the age of the supply pipe. We take both readings at survey. The result decides between a mixer on the mains, an unvented cylinder or a pumped supply, and the shower you can fit.
Do bathroom electrics have to be notified, and who certifies them?
Some do. New circuits, and changes to circuits in the zones around the bath or shower, are notifiable under the Building Regulations. It is certified either by a registered electrician through a competent person scheme or by building control, which Hertsmere directs to Hertfordshire Building Control. Zones around the bath and shower govern what can be installed where, and supplementary bonding is checked. The certificate is issued at completion and your buyer's solicitor will ask for it.
