Free quoteOld gullies often hide right inside your narrow side passage. When you decide to build your side return extension in Chelsea, we must reroute those buried cast-iron waste stacks and sewer manholes before pouring the concrete subfloor, otherwise nasty smells and sewage backups will ruin your new flooring. Bad pipe angles cause blockages. We slope the plastic waste runs into the garden connection.
Gas meters cannot sit trapped inside your finished dining area. You will smell damp soil if the incoming gas pipes stay unsealed inside the floor screed, so we shift the supply line and the external copper pipework toward the front garden boundary. Moving meters takes patience. Certified gas fitters test the joints for minute pressure drops while our bricklayers build the dwarf walls.

Bicycles and wooden planters cannot remain in that rear alley. Removing timber fences and securing tight passage through your narrow hallway allows our team to wheel heavy rubble sacks outside without dinging skirting boards. Dust sheets help somewhat. For a side return extension in Chelsea, timber floorboards inside the hall require thick protective hardboard taped down firmly against gravel scuffs.
Your lawn needs heavy timber boards across muddy turf. Without proper boarding, laden wheelbarrows carrying wet mortar and heavy foundation blocks will churn deep trenches across the grass during autumn rains. Mud tracks everywhere. We place durable tarpaulins over ornamental rose bushes and tie back overhanging branches from next door to keep foliage free of brick dust.


Too many glass roof panes create an intolerable greenhouse effect. Overheating ruins your summer dining when you install oversized skylights without thinking about solar glare or ventilation openings, and cleaning leaves off low-pitch glass becomes a weekly nightmare. Glare strains eyes. A side return extension in Chelsea needs openable roof vents alongside insulated timber sections to balance natural daylight with heat retention.
Thick floor screed delays radiant warmth. Running water-based heating loops underneath porcelain tiles demands meticulous manifold balancing before you commit to final kitchen cabinetry layouts, because an incorrectly positioned heating manifold leaves you with cold zones across the rear threshold. Cold corners breed mildew. We test each loop under water pressure before screeding commences.
Parapet walls require deep lead flashing against the party line. If your boxed gutter lacks adequate drainage fall, trapped autumn leaves and sudden cloudbursts will back up water directly beneath the internal ceiling plasterboard. Water finds every weakness. We form wide zinc gullies with emergency overflow spouts.

Shared boundary walls usually require formal party wall notices because digging foundations close to an adjoining structure can affect their footings. In Chelsea, old Victorian party brickwork is often fragile, so neighbours must receive written notifications and survey schedules before any trench excavation starts on site.
Decorative finishes like kitchen units, bespoke paint choices, and final stone floor tiles are usually bought separately by the homeowner, because personal tastes dictate material costs. Structural steelwork and base plastering stay within the main scope, but specialist appliance connections or designer lighting fixtures require separate supply allowances.
Pack all fragile chinaware, remove wall art, and strip the existing kitchen cupboards completely, because dust penetrates cupboards despite plastic sheeting. Clear an unobstructed route from the back room straight out to your front entrance door so tradespeople can carry materials safely through the property.
The build begins with ground excavation and drainage diversions, followed by pouring foundation concrete. Once walls rise and steel beams sit firmly in place, the roof structure is sealed against rain. Finally, internal plastering, electrical wiring, and subfloor heating precede the installation of sliding patio doors.
