Building regulations drawings in Havering

Extending a larger family house

Where a Havering house has a deep garden, or room at the side for a garage or a two-storey addition, that space brings its own technical choices. A long rear room needs a beam with a long span and daylight that reaches the middle of the plan. A kitchen-diner knocked through the back of the house needs ventilation that suits a larger open volume.

Where an extension joins an old garage or conservatory, we survey and draw how the new floor, wall and roof meet the old, because junctions are where cracks, damp and cold bridges appear. If you also plan to add a floor, the structural calculations in Havering show whether the existing walls can carry it, and our sheets carry the answer.

Loft conversions and bungalows

A bungalow or chalet-style house is often a cost-effective way to gain bedrooms. The loft or roof space is already large, and new rooms do not need to overlap the garden. Building control's checks are strict, though. The stair must give headroom and a safe landing. Rooms on a new upper floor need a way out in a fire, which means a protected route or an escape window of the right size. The floor needs enough strength for a bedroom.

Because the age and build of a roof are rarely on record, we begin every loft or roof project with a measured record of what is there. The set that follows shows each of these items on a plan and a section, so the inspector can see them without asking.

Insulation deserves a note, because loft rooms are exposed to heat and cold at the same time. We show the thickness and type of insulation between and over the rafters, the vapour control layer and the ventilation gap that keeps the roof structure dry, so the finished room is warm in winter and does not overheat in summer.

Decisions, timings and notices

Havering decided 985 householder applications in its latest year, granted 85.9 per cent and decided 97.8 per cent on time. That makes planning predictable, though the figures are history, not a forecast for your home.

Building control body must decide a full plans application within 5 weeks, or longer if agreed in writing. Once the work is approved you must give notice before you start, and the commencement rule also applies: Notify commencement within 5 days after work is regarded as commenced. We prepare full plans because the answer arrives before the builder orders materials.

Havering borders Essex, so some owners compare approaches on both sides of the boundary. The Building Regulations are national, which means the same technical rules apply here as across the border, and a set drawn well for one site is easy for your builder to follow on another. What differs is local: the soil, the sewer connection and the planning guidance that sits ahead of the technical set.

Prices and the levy in Havering

Building regulations drawings start at £845 with VAT included, fixed up front. A second chartered technologist checks every sheet before it is issued, and if the examiner asks for changes we revise the sheets at no extra charge.

A terraced house here averages £435,382 and a flat £251,321, so cost control matters. Havering is in band 3 of the Mayor's scheme at £30.3 per square metre, and the Havering Community Infrastructure Levy Charging Schedule sets £151.52/m² (Zone A, North of A1306); £66.67/m² (Zone B, South of A1306). We flag any levy in the handover pack, together with party wall timing where it applies.
